Adding a second battery — Tesla finally makes it possible
When Lightning Energy installed our Powerwall 2 back in December 2023 https://www.facebook.com/share/p/1Anc2vKKqZ/ it was great. Paired with our 13 kW Enphase/Jinko solar system and 10 kW inverter, it's been handling our fully electrified home in Emerald pretty well — five reverse-cycle ACs, heat pump hot water, EV charging, and grid outages lasting up to nine days. But as we've added more loads, I've been thinking about expanding battery storage. There was a problem, though. The Powerwall 2 is no longer CEC-approved for new installations in Australia. Tesla stopped taking orders for it in late 2024/early 2025, and as of January 2026 it's no longer on the Clean Energy Council approved list. So you can't add a second one. And until very recently, the Powerwall 3 — Tesla's current model — was completely incompatible with the Powerwall 2. They couldn't talk to each other. That meant anyone with a Powerwall 2 who wanted more storage faced a painful choice: rip out the existing battery and…

Heat pump testing — how fast does it heat?
In my December post about our heat pump installation, I mentioned that one of the reasons I chose Emerald was the integrated app. It shows the tank capacity, water temperature, outdoor temperature, and lets me turn it on and off or activate Boost Mode remotely. I've since used it to answer a question: how long does it actually take to heat the water, and does outdoor temperature make a difference? Over the past couple of months, I've been taking semi-random screenshots of the Emerald app at intervals through the day, tracking the water temperature as it heats from "Low" (around 25–30°C) up to the 60°C target. I did this on 11 different days, with outdoor temperatures ranging from about 14°C to 32°C. I then used AI (Claude, by Anthropic) to read all 87 screenshots, extract the data, and plot it on a chart. The chart shows each day's heating curve overlaid, with the lines colour-coded by outdoor temperature — red for hot days, blue for cool days. We might expect to see the warmer days…

Ducted air conditioning (or heating) is inefficient.
Let me explain, and see what you think. I am not a fan (pun intended) of ducted. It seems to be very inefficient. But only one in five air con sales reps seem to agree with my reasoning. At our previous home, in Saratoga NSW, we had a large (10kW) ducted air con system upstairs, which included all the bedrooms. When we just wanted to cool or heat one room, we tried to close the door of that room. But the door would slam shut and whistle, as the air would try to escape. The ducted air con had one or two outlets in each room’s roof. It had one shared return vent in the hall. Turning on the air con in a single room, the air needed to return to the hall to circulate. Closing the door blocked that path and made the pump work extra hard. The thermostat was also in the hall, as part of the control unit. We could set the target temperature of a room to say 22°C, but the room might cool down to 18° before the hall thermostat would register 22°, with a temperature gradient between the two. The…

Goodbye gas! I finally organised disconnecting the ducted gas heating at our home.
If only we could see the burnt gas pouring into the air, all the time, and not just when the condensation highlights it (as in the photos). Pumping carcinogens and greenhouse gases into the air that we breathe. It’s nuts. It was costing us up to $528 per month to run the heating in winter. Our replacement air conditioning will be closer to free, thanks to our solar and battery. We recently also replaced our gas hot water with a heat pump. See my post about that, here: https://www.facebook.com/share/p/17xtnGjv2E/ Our one remaining gas appliance is our stove top. Once that’s gone, we will save $35 per month just for the connection fee. And no more gas! We’re replacing the gas heating with some split air conditioners. Read about our replacement system here: https://www.facebook.com/share/p/18cxsd3qG7/ Follow Tesla Tripping to stay tuned. For those who might say “what about in a blackout”? Note the power point connection on the old gas heating. Our old gas hot water heat pump had one too.…

Multi-head air conditioning installation, stage 1.
tion, stage 1. The original plan was to install a multi head system, with five heads (one in each of five rooms), and one shared compressor, outside. Due to a change of plans (see “Problems” below), we end up with three heads on our multi-head system, covering our downstairs living area (lounge, dining, kitchen), master bedroom, and guest room. Configuration: Shared compressor: 18kW (though much lower in actual use) Head 1: Master bedroom: 2.8kW Head 2: Guest room: 2.8kW Head 3: Living area: 8.4kW Cost: The original quote was for a five head system, including two more 2.8kW heads and a slightly larger 20kW compressor. $14,776 Emerald 20kW with 5 x heads -$7,140 VEECS discount -$386 EOY Sale $7,250 Total inc GST Inclusions: Removal of Gas ducted system 1 (no duct removal) Double storey We paid about 20% deposit up front, and the rest on completion.

I’ve come across a few ICE (internal combustion engine) vehicles that could benefit from…
…charging points. Bear with me here. This ambulance, parked outside a nursing home, was running the engine, with no-one in it, I presume to keep the air con running, on what was a pretty hot day. Perhaps they were keeping the vehicle cool for a patient they were collecting. Fair enough. But, of course this leaks fumes (and noise) into the car park and reception, which isn’t great for health. I noticed that it has a power socket at the rear of the vehicle. I’m wondering if they could plug that into an electrical supply, if there was one at the parking spot (but wasn’t one handy here). This rental van I’m guessing has refrigeration, parked outside a butchers in Emerald. They made use of the external power socket, creatively plugging in from the shop. No noise or fumes. I wonder if it would be handy to have more accessible power points for these ICE vehicles? Or better yet, have electric vans that can keep cool without an engine, and recharge from a power point. One day soon, maybe.

Car camping in my Tesla, beside a creek, off the beaten track in the Snowy Mountains.
It took me a while to find the site. Earlier, in my search, I pulled off onto two tracks that ended up in someone’s property. At least it gave some local kids an excuse to run outside to see what the UFO sound was I did a three point just outside their gate. I waved and grinned. A cup of tea and a snack from my Teraglide drawer, sitting in my camp chair, watching the bush life. Until the bush life started eating me (just a few bugs), signaling time for bed. I again wished I had remembered to pack a collapsible stool, to help climb into the back of the car. Followed by the commando crawl to get on top of the Snuuzu mattress and Teraglide platform. This is the highest sleeping option, which gives lots of storage space and a very comfortable bed. The only down side is requiring more effort getting in and out. Once I’m in, it’s great with plenty of room to move. Please forgive the “Tesla Tripping – after dark” photos. Hopefully it helps give a real world idea of the space inside. Sleeping…

Wow, possibly the best amenities for a road trip, at this spot in the middle of nowhere…
…(in the Snowy Mountains). Seats and tables, beautiful location, playground, water, toilets, WiFi. Even has a shower and laundry tubs. Oh, and a pizza oven. Hard to beat! Gotta love the various signs on the amenities (see photos). Thanks to Gippsland Climate Change Network and Chargefox for the destination EV charger here. It’s probably the only public fuel source (of and kind) for over 100km. There are no shops or food outlets here. Fortunately, I grabbed some supplies when passing through Bombala and Cooma, over the past few days. Instant kitchen: pop the Tesla tailgate, pull out the Teraglide drawer and table, flip up the lid to reveal the fridge in the sub trunk. After a couple of hours to eat and chill, off to find a campsite for the night, nearby along the river. I’ll come back in the morning to use the shower. Charging: The EV charger here is just AC single phase, 7kW. That’s much skewer thana fast charger, but enough to give me 14kWh (about 23%) in the two hours I was parked…

In search for a place to camp tonight, I gambled on the solitary green pin that appeared…
…in the PlugShare app (see screenshot), west of me, way off the beaten track, across the Victorian border, in a little town named Tubbut. Plugshare showed no check-ins at that location, but the Chargefox app said it was functional. WikiCamps also showed some freecamp options around there, so it looked like a good option for the night. It was a beautiful drive, along some windy unsealed roads. I followed the navigation, but ended up in the middle of nowhere, I think due to the Apple Maps and Tesla map using different references. At this point, I wished I had Apple CarPlay, so I could show the PlugShare map on the big screen. Turning back a few kilometers, I found “the town”, which is basically just a community hall with add-ons. Fortunately one of the add-ons is the Chargefox EV charger. It exists! And it works! There’s a fuel bowser across the road (pictured), but I don’t think it’s been operational in years. I think the nearest petrol station is over a hundred kilometers away.…

I wish my Tesla Model Y had a power point, where I could plug in my induction stove to…
…make breakfast 😞. What I need is “V2L”, which stands for “vehicle to load”. Unfortunately, my Tesla Model Y RWD does not have it. This omission almost made us switch to BYD, Kia, Xpeng or one of the many other EV car brands that provide V2L. Tesla’s CyberTruck, new Model YL, and Model Y Performance all reportedly now provide V2L. The Cybertruck has built in power points. The other two require an adapter plugged into the charge port. I can only hope that in the near future Tesla offers some retrofit option for my car. In the mean time, I just have to find a power point, in order to cook. If I had booked a powered site at this location, that would work fine. This morning, I just used the camp kitchen. My car’s massive (by camping standards) 60kWh battery provided air conditioning all night, and has run my camp fridge non stop, via the 16V outlet. It powers other mod cons, such as the lights, wireless phone charging pads, powered tailgate. For more details on this car camping trip, see…

Sleeping in the Tesla, on a Snuuzu mattress, on a Teraglide platform.
The obvious question: can I fit? Short answer: plenty of room to sleep, rollover, look at the sky, out the window, or my phone. I never banged into the glass or support arch. But, getting in is a bit tight. I had to shuffle through, like a recruit in a commando course. I also forgot to pack a collapsible stool, to step onto, high enough at the back to crawl in. The Snuuzu mattress is super comfortable. It has a few layers of foam, supported by an inflatable layer. With the back seats down, the Tesla floor slopes down towards the back, with a kink where the seats hinge. This makes sleeping uncomfortable, and slides the occupants slowly down to the boot. One way to rectify this is to add a slightly elevated floor, that is truly horizontal. That’s where the Teraglide platform comes in. Teraglide also has a basic model, without the drawer, that isn’t as high as ours. And there are car mattresses that aren’t as thick as the Snuuzu. So, my set up here is probably the highest option. This…

Setting up the Teraglide platform and Snuuzu mattress in the Tesla Model Y.
Steps: 1. Folded back seats down, using the buttons in the Tesla. 2. Slid the interleaved top of the Teraglide platform onto the folded down rear seats. 3. Moved the front seats forward. 4. Unfolded the top hinged bit of the Teraglide. 5. Clipped on the side supports of the Terglide, near the doors. 6. Placed the Snuuzu mattress bag on the Teraglide platform. 7. Unzipped the bag, unrolled the Snuuzu mattress. Unclipped the mattress and opened it up flat. 8. Pressed the `Inflate` button on the mattress. Waited a minute for it to finish, then turned it off. 9. Added bed linen, blanket and pillow. Gotchas: 1. Teraglide (the business) had warned me, after seeing earlier photos of my installation a few months ago, that I had neglected to strap down the front of the Teraglide. With this in mind, I brought along the supplied straps, but I hadn’t yet installed them. When I fully extended the kitchen drawer without anything weighing down on top of the platform, the drawer started to tip over,…

We checked out the new Tesla Superchargers in Batemans Bay. Super fast.
The fish and chips shop next door didn’t have anywhere to eat. The Catalina Club, which hosts the Tesla chargers in the car park was the obvious choice for lunch. We needed shoes to get in 😉. And ID. What a great find. Good food, impressive facilities. Thank you Marie for showing us around. Charging: Charging finished by the time we ordered dinner, so I had to move the car. Unfortunately, no shade in the car park on a very hot day. I kept the air con running in the car to keep our belongings and food cold. No engine, no fumes.

What to ask for, in a battery installation?
I suggest getting your installer to agree in writing that your battery installation will include: 1. Remote control via an app and/or website to monitor your battery and house power. 2. During a grid outage, the battery should provide backup for everything you need. 3. During a grid outage, solar continues to provide power. 4. The ability to curtail export of power to the grid when pricing is negative. 5. Compatibility with Amber Electric, if you might want to use them as your energy retailer. Let’s look at each in detail: 1. Using an app or website, you can: 1. Monitor power in and out of your battery, house and grid connection, instantaneous, daily and historical. 2. At any time, set your battery to a minimum charge percentage. 2. In the event of a grid outage: 1. The battery will switch over automatically. The installer should test it and show you. 2. The battery will power all of your home, up to the battery’s maximum power (which should be at least 5kW). 3. If you have three…

What do all the electricity measurements mean?
1. Australian household electricity runs at about 240V “volts”. All your power points and devices are 240V. This is basically a measure of the force used to push the electricity. 2. The “current” is basically the throughput of electricity, measured in Amps. It varies for different devices. A modern LED light bulb uses less than 0.1A (Amps). A toaster or heater will use around 8A. The typical maximum allowed by a standard power point is 10A. 3. The total power of the electricity is measured in watts. We multiply the volts by the amps (voltage x current) to get the watts. For example, if your appliance uses 5A at 240V, then that’s 5 x 240 = 1,200 W, which is 1.2kW (kilowatts). A light bulb uses less than 0.1kW. 4. The total energy used by a device is calculated as the power x time. For example, if you use an appliance running at 1.2kW for 10 hours, then it uses 1.2 x 10 = 12kWh (kilowatt hours). A light bulb could run for days on the same 12kWh. 5. When you use electricity from the…

Home Battery Introduction
Are you considering a battery for your house? Here is a basic introduction, based on our experience. I hope it’s helpful. Please comment about any errors, omissions or questions. 1. Why is there more talk lately about getting a battery for your house? 1. As of July 1 this year, the federal government will pay for 30% of your home battery purchase. This makes it 30% cheaper to buy one. 2. What’s the purpose of a house battery? 1. A battery provides power to your house, as electricity. 2. It can power anything in your home that runs from electricity, including your fridge, lights, power points, TV. 3. It can keep your house appliances running when there is a grid outage (a “blackout”). 4. If you have solar panels, a battery can store the excess power generated during the day, so you can use it at night to avoid paying for electricity. This is why it is often called a “solar battery”. 5. You can also charge a battery from the grid when electricity is cheap, and use it when electricity is…

A few neighbours and friends have asked us lately for advice about solar panels, house…
…battery, EVs etc. Here’s our real life experience, starting a series of posts on different topics. We installed solar and battery when we moved into our house (Emerald, Victoria) about two years ago. We already had an EV (electric car). This week, we finally got around to replacing our gas hot water with an electric heat pump. Next month we’re replacing our gas ducted heating with a multi head split air conditioning system. Overall, our solar and battery provide more electricity than we use. We’re also connected to the electricity grid so we can import when we need more, or export when we have a surplus. We aim to produce all the power that we need. On the rare times that we import electricity from the grid, our retailer bills us. More often, we export our surplus electricity to the grid, for which they give us a credit. Overall, we have more credit than debits, so we don’t have to pay anything. All this depends on your electricity plan, which I’ll discuss in a separate post. The…

Heat pump installation
We finally got around to installing a hot water heat pump, to replace our gas hot water system. We were paying about $40 per month for our instant gas hot water (plus $40 connection fee). Now we’re paying nothing, because the heat pump is just using our excess solar power. Without solar, I estimate it would be costing us $8 per month to power it from the electricity grid. There are a few incentive schemes around to replace gas (or other old inefficient systems) with a heat pump. An installer will factor these into their quote. The subsidies can be significant. In our case, the total price was $4480, but it was reduced to $1650 for us to pay, after subsidies were subtracted. A hot water heat pump uses the same principle as an air conditioner (which is also a heat pump). It “pumps” heat from one side to the other. In this case, it pumps heat from the outside air into the tank of water. The basic physics is that when you compress air in a confined space, it gets hot, and when you expand…

Our home Powerwall battery is one of a million deployed so far.
The Tesla app celebrated by listing the stats of our install, and the fleet as a whole. Our battery has saved us (and our neighbours via extension cords) from 13 days of blackouts, without any noisy smelly generator, or trips to refill it with petrol. Our solar system has generated 16MWh of energy so far, used by our house appliances, home battery, our car and exports to the grid. At an average ball park price of say 15c per kWh, that’s $2400 worth of electricity, with no ongoing running cost.

After two years in the Dandenong Ranges, we finally visited the Dandenong Ranges Botanic…
…Garden. Amazing to see in Spring. It’s a huge place. I think we covered only 20% of it. Parking seems to be extremely limited and unmarked, in a dirt section across the road, which led to highly questionable parking. Charging: Today’s trip was partly due to a frequent oddity of owning an EV. We had an excess of fuel. It feels like a shame not to use it, for free. The solar production from our roof fully powered our EV, home and house battery, and it wasn’t worth exporting any to the grid (negative feed in tariff). Fortunately, as you can see from the graph, the Amber app shut down our solar production while we were away, after our home battery was fully charged. All automated, so we didn’t have to do anything.

We arrived a day ahead of schedule at Ayers Rock Campground.
We had booked a powered site, starting from tomorrow, but none were available tonight. The staff offered us the unpowered overflow campground area. Our original plan was to charge the car at our powered site, while also running the air conditioning and accessories. Without a powered site tonight, we had to charge up the car a bit first, so we could just run it off the giant battery. We used the auto inflate button on our Snuuzu mattress, added pillows and doona. We moved the baggage to the front seats, so the bed wasn’t obstructed. While car camping in Coober Pedy a few days ago, we discovered that even with our portable wheel ramps the car’s bed floor still leans backwards too much. So, we backed the car up a small hill as well. We used our fold up spade to fill in a couple of holes from previous campers. We set the Tesla to “camp mode”, so we could sleep in the back of the car at 20°, while it was 3° outside, overnight. The trudging to the toilet in the middle of the night a couple…

Although it’s in the middle of nowhere, Spud's Roadhouse is a great place to stop on the…
…way to Uluru. For one, it has a few EV charging options. Now, charging should be simple, like it was for the two EVs that were here when I arrived. They each plugged into one of the two DC charging cables, walked over to get some food at the roadhouse while their cars charged. Then off they went – one towards Adelaide and the other to Roxbury. But life isn’t always so simple. I plugged into the remaining charger, which is a slower AC station. It’s only 7kW, compared to the faster DC adjacent chargers at 80-150kW. But, that’s fine – I’m staying here overnight, so I have the time, or I could have just used a fast charger when one of the other drivers disconnected. This AC charger requires your own “Type 2” (technically “Mennekes”) cable, which we have, so I plugged it into the car and EV charger. To my surprise, it immediately started charging, without using an app or tap card. I left it connected and it was at 93% after we finished dinner. I went to unplug it, which should be easy,…

Lots of cyclists out today, including this giant Saint Bernard. The local park has interesting seating, or perhaps a one turn swing set 😳. I checked in on our parked car from the Tesla app, after some dodgy parking in front of us. We love driving through the fern trees and tall timbers of the Dandenong Ranges. Beautiful all year ‘round.

This is probably the busiest we’ve seen our town of Emerald, Victoria. T
he Lost Woods Market draws a huge crowd. It’s a beautiful stroll through the tall trees, past numerous stalls and food outlets, with Puffing Billy Railway choo-chooing past every now and then. It’s a magical place. We parked up the other end of town, starting off with brunch at Over the Road Cafe, then walked through the jammed main road to the markets. The generators of many stalls lined the back path, filling the air with slight fumes and noise. It’s a shame they don’t have grid power. We hoped to see some stalls powered by V2L EVs, as we’ve noticed at some other markets, but none here. Charging: While we were away from home, the sun charged up our home battery. When we returned, it switched over to start solar charging our car. Win win.

We arrived back home, in Emerald Victoria. Autumn is still in full swing. 🍂
Charging: We charged up for just a few minutes in Yea earlier, since we could fill up cheaper at home. But when we arrived home, our area had a grid outage. Our house PowerWall battery kept our appliances going until the grid was restored. In an alignment of failures, our solar system also stopped producing electricity 😩. So, we can’t charge up the house or car battery from the available sun. We’ve raised a fault with our installer, Lightning Energy, who can hopefully find out what’s going on with our Enphase system. It’s not the first failure. In the mean time, the grid has reconnected, and we’ve charged up during the cheap power times in the day, when renewables are mostly powering the grid.

Imagine driving an ICE (internal combustion engine) car for the first time, coming from…
…EVs. April 5: We drove in a couple of ICE cars around town (Airlie Beach and Cannonvale) for a few days. It reminded me of a couple of years ago, hopping back in our Mazda CX-5, after owning an EV. Here are my observations: 1. You can’t charge it up while parked at home, or at a shopping center. You have to go to a special “fuel station” to recharge the car. You can’t just leave the car to recharge – you have to stay with it, holding the recharge nozzle. 2. It smells. And the fumes are carcinogenic. The fumes come from the nozzle, but also out of the back of the car while driving. 3. When the car has enough charge (fuel), you put the nozzle back in the pump. But then you have to walk into the service station to pay at the counter. It’s not automatic at the pump, or it’s too complicated for most people to bother that way. 4. There’s a possibility of fire. The fuel is highly flammable. And the car actually combusts that fuel to make the car go. There are about 7 ICE car fires each day…

Off to The Macedon Ranges today, for a Mystery Adventures Picnic.
It’s basically a foodie treasure hunt. Great Christmas gift, thank you Helen 😋. First stop at 3 Little Pigs Gisborne cafe, for coffee. Then, on through Watt's Fresh Woodend, Kyneton to Malmsbury, stopping along the way for a food platter, chocolates, bits, drinks and bread. Picnic at Malmsbury Botanic Gardens, with a walk to the Malmsbury Railway Viaduct. Charging: Charged up at home yesterday using solar, even though it was a fairly overcast day. 100% charged battery was enough for the trip there and back, plus Sentry Mode and keeping the air con running while parked at each stop along the way (to keep food and cabin cool). Returned home with 8%, ready to charge up again. Easy.

The final stretch of this 4000km road trip, to get home.
We stayed last night in Gobbagombalin (near Wagga Wagga) with our grandson (oh, and his parents 😉). Just a couple of bakery stops, in Holbrook and Yea. The first cafe in Holbrook was closed, so we looked through the window like lost puppies. While parked, we kept the car in Camp Mode, with the air con on, to keep our camp fridge going and our food cool. No exhaust or additional heat. Charging: The car's navigation suggested charging in Wangaratta, but we ignored that and just charged where we stopped for a break. Since we were stopping anyway at Holbrook and Yea, we parked the car at the Superchargers in each town, so the “tank” could fill up while our bellies did. So easy.

It’s been wild 36 hours here in the Dandenong Ranges. Y
esterday afternoon, the power went out in our town of Emerald. We heard it was due to a fire somewhere. We sent out a few texts to our neighbours to offer our battery backup power. We ran our heavy duty extension lead over the fence and set up a power board on the front porch for phone charging. A few hours later, the grid was back up and running. But, the pending storm warnings made us cautious. Sure enough, an hour or so later, the storm hit. Heavy rain, pounding hail and strong wind. Marvin the robot mower happily sits charging out in the rain. But I didn’t fancy the chances of his camera eyes surviving the hail stones. I used the iPhone app remote control to drive it under our pergola, while the ice golf balls bounced on the lawn. Sure enough, the grid connection died again during the night, probably due to storm damage to power lines and other infrastructure. In the morning our neighbour reconnected to our power supply. We inspected the hail stones that had formed a layer on our…

After a beautiful morning drive in the Dandenong Ranges, with our last stop at John’s…
…Hill Reserve Lookout, we decided to head for home, about 20 minutes away. It was 6°C outside but warm and toasty in the Tesla. Our house was going to be cold 🥶. If only there was a way to heat it up remotely, before we got home, like we can with the Tesla 🤔. Fortunately, there is! We bought a Sensibo remote control. It communicates with the air conditioner via infrared, and communicates with our phones via the Internet. It even works with our ten year old Panasonic air con. So, we can be in bed, or many kilometres away and say “Siri, turn on the air conditioner”, to have a warm lounge room waiting for us. We can also control the temperature, fan speed, schedule and so on. We could even set it up to turn on the air conditioner automatically when we’re within 20km from home, via geofencing. Nice 😊 We opted for the “Air Pro” version, which also monitors air quality. I’ve noticed that it sometimes shows a spike in airborne particulates, which I suspect is when neighbours fire up their…

cat, Archie initially hissed a few times at the interloper, but seems to have now accepted (or at least tolerated) her. We took this fine old doggie out for a drive to Loch. We limited the G forces of acceleration and cornering so as not to plaster her on the back seat. We had a delicious lunch with friends at the Loch & Key cafe, while Clare slept in the car, in air conditioned Dog Mode comfort. We checked on her a few times using the in-cabin Sentry Mode camera. Then out for a long walk around the town of Loch.

The bare feet were feeling the 3.5°C this morning as we packed the car in Bombala.
First stop 100m away for coffee and an egg and spinach roll at Kitchen Eightyate. Tom spotted Bombala Lookout on the navigation a few minutes away, and couldn’t help himself for the photo opportunity. Then onward south towards Cann River, past the “no fuel” sign. Charging: Since we disabled Sentry Mode last night, the car still showed 27% battery charge this morning. By the time the battery preconditioned (warmed up), we grabbed coffee and visited the lookout, the charge was down to 24%. It estimated arrival at the Cann River Superchargers with 7%, but that was reduced along the way to be 1 to 3%, due to climate. We kept using the car as normal, with air conditioning, heated seats, phone charging etc. We did reduce speed a bit, partly due to the wet road and partly to increase range. In retrospect, I probably shouldn’t have diverted to the lookout. Or we probably should have topped up in Narooma, before this trip away from civilisation 🤔. Stay tuned to see if we made it! 🫣

Double the EVs and double the ice creams.
This time I took a large container to Bam Bam Italian to buy four double scoop ice creams for us and our guests. The car kept the temperature at a chilly 15°C while Kyla accepted the challenge to scoop two spheres into each cone. Tomorrow, we’re off to Emu Plains Markets. Charging: Our guests arrived in their BYD Atto 3 just in time to get the few scraps of solar power from our wall charger. Then we paused the charging until after the peak demand period, resuming after 10pm, mostly from our Tesla Powerwall battery.

The challenge: In the middle of the hottest three day stretch in Victoria in decades…
…bring home double ice cream cones without them melting all over the car. Solution: Set the Tesla to “ice cream mode”. Well, it’s really just the “keep” setting in the air conditioner. It keeps the car cool, without running an engine, while I exited to buy ice cream cones at Bam Bam Italian. Mission successful! 🍦😋

I tried out another “EV”, kind of – an Electric Vegetation cutter 😉. Okay, th
at’s a bit of a stretch. It’s an electric hedge trimmer. Emerald has so much vegetation, and our place is no exception. Hundreds of meters of hedges. The RYOBI electric hedge cutter is fairly quiet, instantly turns on and off, and is fueled for free by the sun via our roof solar panels. While cutting, it did occur to me that using a petrol powered hedge trimmer would be a much less pleasant experience. Much louder, with fumes in my face, heat and higher fire risk. I’d be dependant on an external fuel supplier to truck in petrol from hundreds of kilometers away, and I’d have to drive to a petrol station to get it. When the battery goes flat on this electric model, I just plug it in and walk away to do something else. It will take an hour or more to recharge, but I don’t have to do anything. Plugging in the battery takes a few seconds. If I really wanted to keep going immediately, I could swap with another charged battery, but I like the forced break 😉. I am aware that lithium ion…

It’s been nine days of grid power outage here in Emerald Victoria. T
he community has pulled together to share resources. Today I received an SMS from Ben to ask if he could charge at our place. I assumed it was another neighbour asking if they could plug their phone or laptop in to the power board we laid out in the porch. We were the only house in the street to still have power after the storm hit, thanks to our Tesla Powerwall battery. It’s been charging up each day from solar panels on the roof. But Ben was actually after a place to charge his EV. I had forgotten about our listing on PlugShare during all of the neighbourhood blackout dramas. I said yes, no problem. Today he had driven from his home in Packenham east to Sale, then back west and up the hills to Emerald, and has a few more nearby drives to do before returning home. The navigation said he would get home with 8% charge, but that wasn’t accounting for extra stops. So, he wanted to play it safe. Charging: He plugged in here for about ten minutes, drawing a max power of about 7.2kW from…

We’re are back home in Emerald and have power!
The grid is still out, and is expected to be down until mid next week. But our house is getting power from solar and our Tesla Powerwall battery. Driving back home (after our road trip to NSW), we could see why Emerald is still in the dark. Many power lines (and phone/broadband lines) are still down. Emerald featured in the first story on last night’s (Friday) ABC news: https://iview.abc.net.au/show/abc-news-vic At least one of our neighbours is running a fuel generator. Another has a couple of solar panels hooked up to a car battery for night lights and a 12V car fridge. Schools are effectively closed. The local petrol station had one pump going, with a long queue. We have offered our neighbours electricity from our solar/battery power. One family had no power for three days, but now we have connected some extension cords over the fence. History: The grid died on Tuesday 14th. We were away road tripping in NSW. Our Tesla Powerwall battery continued to provide backup power to our…

Well, that’s not good. The Tesla Powerwall at home has just gone flat (zero percent…
…charge) at about 5pm today. Our new home town of Emerald is one of many affected by the grid outage in Victoria, after a wild storm hit on Tuesday afternoon. A couple of months ago, we had Lightning Energy install solar and a Powerwall battery at our new home. In a grid outage, the solar array is supposed to keep the house electricity going, recharge the battery each day, and keep the fridge cold. But the solar production stopped working when the grid outage started. Something is wrong with the installation. See the lead up story in our previous post: https://m.facebook.com/story.php?story_fbid=439045192389797&id=100088529584679 The battery has slowly depleted, until it hit zero percent two days later (this afternoon). I contacted the installer, Lightning Energy, a couple of days ago to hopefully fix it before the fridge died. No answer from service. So, I SMSed Andrew, who works for them and lives locally. He kindly offered to pop in on his way home to take a look. Here’s hoping we…

Wow, what a wild weather ride in Victoria yesterday.
We’re still in NSW, but the Weather app summarised the weather at home in Emerald as “Fire Weather” 😮. The heat was followed by a heavy storm that knocked down many trees and power lines. In the middle of the day, wholesale electricity prices peaked at a hundred times the norm at nearly $20 per kWh (normally under 20c per kWh). I checked our home remotely using the Tesla app. It was exporting power from our battery (and solar) to help keep the grid supply going, whilst paying us about $100 per hour for the supply! Our battery has continued to supply power to our home during the blackout. We messaged some of our neighbours an invitation to come over and plug in any needed devices (such as phones or a portable fridge). A few of them also checked on our house for us. Great neighbours and community ☺️. We might need to also offer them showers because those with on demand gas hot water often need electricity to light them. All the petrol stations in the area are also closed. We hope to be…

In preparation for starting our road trip tomorrow to NSW, I want to protect my new found…
…Victorian sensibilities against the harsh heat and humidity up north 😉. Fortunately, Helen bought me a great Christmas present for the job: a ventilated seat cover! I know the Tesla Model 3 new “Highland” 2024 model comes with built in ventilated seats. But our 2022 Model 3 does not. Installation was fairly simple. I just looped the hole over the headrest, spent several minutes pulling it down hard, far enough to pop in under. I pushed the back of the cover under the plastic back of the seat. I couldn’t find something under the seat for the hooks to grab. It is powered by the 12V outlet in the centre arm rest. It does the job well, preventing my back from getting sweaty and sticking to the seat. I wish I had this for our earlier Queensland trips. The mini fans in the seat cover keep my back and bum ventilated and cool. The buttons allow setting the different fan speeds. The seat feels a bit lumpy, especially where the fans are. It makes a high pitch fan noise, especially when I move…

Tesla battery and wall charger installation.
The team from Lightning Energy installed the undercover pieces today, while it’s raining, and deferring to tomorrow the installation on the roof of the solar panels, if the sun comes out. We had originally scheduled this installation for December 11 and 12, but rain on December 11 saw it canceled. We had this Tesla wall charger at our last house in Saratoga NSW, a year ago. The new owners there didn’t have an EV, so we modified the contract for us to remove the EV charger. It has sat in storage until the removalists delivered our belongings here a few days ago. It wasn’t really practical for us to bring the Tesla “Powerwall” battery with us from the old house, so we bought a new one for this house. It costs about $15k, which is a lot. There are cheaper battery options, but we know the Powerwall has a large capacity compared to cheaper batteries, and works well with the app, scheduling, blackouts, etc. We have heard from a few people in Emerald and the Yarra Ranges in general that…

Here’s an update on our planned solar installation, in Emerald Victoria, since some have…
…asked. We were hoping to fill the sun facing part of our roof with solar panels. Lightning Energy has been great (Hi Andrew 👋). They put together a detailed initial proposal for us that would have given us 15kW of electricity from 34 solar panels (0.44kW each panel). The plan was to use that to charge the EV (7kW) and house battery (5kW), hot water, air conditioning etc. If/when we couldn’t use it all, we would export 5kW back to the grid. In a disappointing turn, we learned today that AusNet has rejected the proposal and capped it at a max of 11.9kW solar panels and 1.5kW export. So, our installation will be restricted to match 😢. The 11.9kW max solar production would only happen in full sun, in the sunny months of the year. On cloudy days, or in the middle of winter, solar panels only generate a fraction of the max power. For example, we might only generate 50% or 6kW on a sunny day in winter. The main disappointment with the AusNet system limit is that it reduces our capacity to…

The final leg of our return trip from Airlie Beach in Queensland, to the eastern suburbs…
…of Melbourne. We left our accommodation at The Jolly Swagman Motor Inn Holbrook, then a brief stop at Chiltern Rest Stop. At lunch time we grabbed a couple of salad sandwiches from Mawsons Bakery Cafe, in Euroa, and ate them in Seven Creeks Park while the car charged and kept Archie in “cat mode” (shh, don’t tell him the proper name for it) air conditioned comfort. Then on to Croydon Vet Clinic and Lou Lou's Cattery and Small Animal Boarding Pty Ltd, and finally our last temporary accommodation at our generous sister Helen’s house in Knoxfield. In the pantry, we found our last bag of Brookfarm Granohlaah for breakfast the next morning! Charging: We left our motel with about 85% battery from overnight charging. There were no handy external power points but our host suggested plugging into an inside power point. Our extension cord fit neatly under the door. The power point didn’t feel hot when tested at night, but after a brief charge in the morning (after the coffee run) the prongs…

November 19 - 20: We paid our final visit to our storage shed at Storage King, Lisarow…
…to pull out the cat carrier. Today we finally picked up our cat, Archie, from Cat Utopia Resort & Spa in Doyalson. He’s been there all the time that we’ve been road tripping and searching for a new home. He was very chilled in the Tesla, snoozing for most of the trip. When we stopped for a brief lunch at Campbelltown Catholic Club and dinner at Oliver's Real Food Gundagai, Archie stayed in the car set to “dog mode”, which keeps him in air conditioned comfort. When we arrived at Jolly Swagman Motor Inn Holbrook, Archie checked the perimeter a few times in our room, peering out the window. Tomorrow, we complete our migration to Melbourne, taking Archie to Croydon Vet Clinic, and a brief stay at Lou Lou's Cattery in Bayswater North, while we get our house ready in Emerald Victoria.

We woke in our Ballina Glamping tent at Ballina Beach Nature Resort.
It’s a great setup. Hot shower, four post bed, dishwasher, swing chair, stove, power points to charge phones and car. Yeah, we know how to camp! Not sure about the efficiency of the air con in the tent, but maybe not much worse than many uninsulated houses. Lovely staff and setting. We set off south along the south bank of the river, towards our next night’s stop near Kempsey. Charging: We plugged the car into the power point on the deck of our glamping tent, over night. We didn’t get a full night’s charge, because we got back from dinner in town at about 8pm. In the morning we had about 90% for our new day’s trip.

We’re driving from Mackay to Rockhampton today. I
t’s one of the longest stretches of “not much here”, with signs along the Bruce Highway like “Still a long way to go, kids” and trivia questions/answers. We stopped for lunch at one of the few options along the way: Flaggy Rock Cafe. It’s a great little place with good food. The cars jostle to find parking in the shade. We moved the car out to the RV section to park under a tree, and kept the air con running to keep our food cool. A bit further down the road, we stopped briefly for the toilet at the Marlborough Service Station, with a reminder that we’re not paying $2/L for petrol 😮. Charging: We charged up to 99% at the DC fast charger in Mackay, while getting coffee. It would be great if the Flaggy Rock Cafe had a charger, but alas, no. The Tesla navigation said we would reach Rockhampton with about 9% remaining, which is fine. Since we stopped for a few minutes in Marlborough anyway, we plugged in while there, which upped our arrival in Rockhampton to 22%. Our accommodation there…

After three days in and around Yeppoon, we headed back inland to Rockhampton.
We parked next to the library and grabbed lunch and a coffee at The Two Professors cafe. We found Fantastic Furniture to try out some lounge options, much to the amusement of other customers. The lounge is not for the Tesla, but for our soon to be new home in Emerald, Victoria. Not enough boot space to transport it from here, though 😉. Next, Capricorn Caves. Charging: Three days ago we arrived in Yeppoon, with 70% battery charge. There was nowhere in Yeppoon to charge. After a few days trips, sentry mode etc, we left Yeppoon with 20%, arriving in Rockhampton with 9%, (37km) as predicted by the Tesla’s navigation. We turned off the air con fan for the rear, which was probably triggered by the luggage weight on the back seats. The Tesla only shows Tesla branded chargers en-route, and warns if it can’t find any. There are no Tesla superchargers in far North Queensland, yet. But we can type in a town’s name and “charge” to navigate to other branded chargers. That took us to the…
Formerly: Tesla Tripping
Come along on our EV road trips around Australia and Europe, and follow as we progressively electrify our home in Emerald, Victoria.
Join us on the road. We set off in late 2022 and drove eastern Australia in our Tesla Model 3 — Sydney, Dubbo, Armidale, Brisbane, Cape Tribulation, then down through Queensland and back. We've since upgraded to a Model Y.
We've kept exploring — Uluru, the Snowy Mountains and Gippsland, and a longer run through Europe in 2024. There's plenty more on the map, so come along for the next leg.
At home in Emerald, in Victoria's Dandenong Ranges, we're progressively electrifying everything: rooftop solar, a home battery, a hot water heat pump, air conditioned heating and cooling, and EV charging straight from the sun. We're going fully electric, off the gas.
Got questions, or insights of your own? We'd love to hear them — please drop a comment on any post.
