Adding a second battery
When Lightning Energy installed our Powerwall 2 back in December 2023 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 start fresh with new hardware. For me, that…

First Tesla service call: a new wheel
First service call for our Tesla Model Y. Replacing our loaner wheel with a new wheel. As you can see in our posts from a few weeks ago, we hit a pothole, damaging our left rear wheel. At the time, we only knew that we had a slow leak. We logged the problem in the Tesla app. They arranged for roadside assistance to come to us, in about an hour, to install a loaner wheel, and take ours away to diagnose. Today, Tesla replaced the loan wheel with a new wheel, costing a whopping $1319. I asked them to clean the damaged wheel and put it in the back of the car. In the photos, you can see the buckle and crack. I am wondering if it is fixable. When I booked this service in the app, I also asked them to fix the water in the light bar, and some issues with the steering wheel buttons. They replaced both. I’ll discuss the steering wheel buttons in a separate post. All covered under warranty. I had a bit of trouble figuring out where to leave the car. Several after me also mistakenly parked in…

Why are utes always the aggressive ones?
Why does it seem to be utes that are predominantly aggressive on the road? A few unnecessary and dangerous overtakes on my way home through Gippsland. Towards oncoming cars, or a kangaroo. Wildlife and police also out. A bit busy on the roads today. Glad to see that the latest software update on the Tesla now shows speed and details now on playback of videos.

Flat tyre — part 2 (the callout)
Flat tyre – part 2. We arrived home yesterday with a slow leak in a tyre. I opened the Tesla app, tapped on Roadside -> Flat Tyre, selected which wheel, and added a note about the slow leak. I received a response with a couple of minutes. About an hour later, Alan arrived to replace the wheel. Tesla subcontracts the roadside assistance to other companies, like this one. They have a bunch of Tesla wheels ready to go. Neither of us could find the source of the slow leak, but that’s not his job. He just tagged the wheel and sends it to Tesla for inspection and repair. Pretty seamless operation. We have a replacement wheel fitted, in less time, including the call out, than it would have taken me to do it myself with a spare. And they take care of sending the original to Tesla. We have a “space saver” spare wheel. If we had taken that with us on the trip, it would have majorly impacted our storage space. But worse: we would have had to then pack the full sized original wheel into our boot…

Oli burger and FSD on the Hume Highway
Lunch stop at Oliver's, just outside Gundagai. I recommend the Oli burger 🍔. Tesla Model 3 with stripes parked near us. FSD along most of the Hume Highway. It does a great job, and avoids human fatigue. A few complaints, though, including it repeatedly thinking that the speed limit is 100, even when it’s actually 110 (pictured). Occasionally it dropped to 80 or 40, presumably after seeing some random sign off the highway. Pretty good driving efficiency with FSD, too, about 14kWh per 100km. See screenshots.

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 the kW and kWh measurements mean?
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…

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…

Our car drives itself: FSD lands in Australia
Our car now drives itself! We choose the destination, and it drives all the way there, turning left, right, indicating, changing lanes, negotiating roundabouts. It’s amazing and boringly uneventful – a combination I heard called “bore-mazing”. Tesla released FSD Supervised in Australia a few weeks ago, for purchase ($10k). This week they also started offer it as a monthly subscription ($149 = $5 per day). We subscribed for one month to try it out. Yesterday I was picking up Amber from Melbourne airport, and decided to try FSD on the way. I paid the subscription through the Tesla app. It seemed to be instantly available, with no additional software download. I hopped in the car. It read my destination from my linked calendar. I pressed the FSD button. The car started reversing out of my driveway. At our street, it failed to figure out what to do, and started heading the wrong way down our no through road, over the grass. Francis was watching from the garage, keeling over with laughter.…

Our Powerwall — one of a million deployed
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.

Parking seems to be extremely limited and unmarked, in a dirt section across the road, which led to highly questionable parking.

No, my Tesla didn't cut off my arm
For those who might have seen “Massive Tesla Recall”, headlines: No, our car window does not cut off my arm 😉. The car has already updated to the latest software version, a few weeks ago, including the latest fix. I do find it annoying that it is referred to as a “recall”, since that implies that the car has to be returned for some physical fix. It is just a software update, which is handled automatically. Having the fault isn’t great, in any car. But having a car that can fix a fault while I sleep, is pretty impressive.

Charging confusion at Spud's Roadhouse
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…

Why our Tesla has no spare tyre
Tesla, and many other car manufacturers, don’t include a spare tyre, or a dedicated place to store one. Tesla encourages owners to just ask for help via the Tesla app, if they get stuck somewhere with a flat tyre. The response time and service is reportedly pretty good. But, what if you’re going to drive well off the beaten track, and want to keep a spare with you?

A new find: Ripe Cafe in Sassafras
In life you need goals. Today’s goal was to find a cafe we hadn’t yet tried 😉, in our home of the Dandenong Ranges. Ripe Cafe in Sassafras was a great find. Guacamole (avo toast) topped with thin sliced potato crisps, and zucchini slice. 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.

Space-saver spare wheels for EVs, $395 to $900
A couple of “space saver” spare wheel/tyre options at Melbourne International EV AutoShow. Pricing ranging from $395 to about $900. We haven’t had a flat tyre during 100,000km of EV driving. If we do, we can contact Tesla via the Service option in the Tesla app. Or we can try out the pump and tyre goo we have in the car. But we’re planning to soon drive to Uluru, where a flat tyre could take quite a while for Tesla or The NRMA to sort out. So, we’re considering taking a spare.

First time charging on the Wangaratta rooftop
Our first time charging at the rooftop in Wangaratta. We stopped here to grab some shopping. Up a few ramps, the T signs pointed the way. The signs to find the chargers were good, but the signs to exit the roof by foot were hard to find. We walked towards the lone Tardis looking box, which turned out to be a lift. Other signs said that it’s all paid parking now. So, we paid 60c through the Easypark app, for 30 minutes. It seemed odd for a short stop at a shopping centre.

Emerald's Lost Woods Market draws a crowd
This is probably the busiest we’ve seen our town of Emerald, Victoria. The 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.

Farewell to our 2022 Model 3
Farewell old friend. We traded in our “old” 2022 Tesla Model 3 today. It was unexpectedly emotional to say goodbye. So many great road tripping memories. 2022 Tesla Model 3 RWD White paint + White seats + Enhanced Autopilot + Boom box and Pedestrian Warning System 91,000km We ended up just going with the Tesla trade in quote of $27k. We could possibly have got $35k if sold privately, but it would have taken time away from work. And since it’s a business purchase, trade-in was just simpler. Our car was in great condition. It runs as well as the day we bought it. It has a few stone chips, paint chips around a side mirror (from reversing against a leaning wire fence), and a bent front license plate. I used my high tech equipment to straighten the plate. But I left the rest for Tesla to spruce up, since they have all the expertise for that. They can also replace the air filter and the rear tyres, which are due for replacement. Trade-in was all managed through the Tesla app, including…

Today we picked up our shiny new Tesla Model Y “Juniper” from Tesla Mulgrave. Most of the process was done through the Tesla app over the past week, so the actual pickup was super sleek.

Thanks to Nathan for leading us to our new car, and sharing our excitement, since he has also ordered one. He left us to inspect the car and said to just turn on the hazard lights if we had any concerns or questions. We spent 15 minutes looking over the car and taking photos. Then we just drove out of the building, to take it home. We have new custom plates “TRIPNG”, but we didn’t get to VicRoads in time to allocate them today.

Why we ordered a Model Y 'Juniper' launch edition
Back in January, we took the plunge and ordered a new Tesla Model Y “Juniper” launch edition. “Ultra Red”, white interior, 20” wheels (which was the only option for the launch edition). We chose the same battery and drive as our Model 3: RWD (rear wheel drive), LFP battery (no nickel or cobalt), 0 to 100km/h in 5.9s. The main reason for the upgrade is for the greater ease of getting in and out of the car, which has been increasingly painful on Fran’s arthritic hips. As those of you who follow our Tesla Tripping blog will know, we have looked at and test driven quite a lot of other options. The best contender was the XPeng G6. In the end we stuck with the Tesla Model Y because of the huge storage space, driving performance and the tech. The Tesla app has guided us through the whole process up to now, with registration, trade-in, insurance. Today is delivery day. The final `Start` button is still disabled in the app. I’m guessing it will enable at exactly 3pm, when we’re at Tesla…

XPeng G6 — second test drive
We took another test drive of an XPENG G6, this time from a new dealership in Berwick, Victoria, which is closer to us. Nice interior, comfy seats, great tech. The handling wasn’t bad on some windy roads, but not as sporty as the Tesla Model Y. Disappointing storage. The auto driving hesitated quite a bit around bends. The lack of full stop on one pedal driving is annoying, but they will reportedly solve that in a few weeks via an OTA (over the air) software update. The G6 includes auto parking and lane change, which costs extra in a Tesla. It has vehicle to load, but it requires some adapter plug into the external charge port, which wasn’t available. We had a chance to play with Apple CarPlay, which is great to have. But the XPeng doesn't seem to support pinch and zoom in Apple Maps, which makes it very limited. Acceleration was terrible (doesn’t move for a second), until I turned in “launch mode”. I couldn’t figure out how to enable launch mode and regenerative braking (x-pedal) at…

Tetris-ing four people, a fridge and luggage into a Model 3
We know our Tesla Model 3 can fit a 50L camp fridge. And we know it will take a large travel suitcase, or four people and some luggage. But we didn’t know if it would take all that at the same time. It took a fair bit of Tetris-ing, and the boot strained at the seams, but we managed to get everything in. I think we might need a bigger car. First stop at Eumundi Markets. We parked in the shade and later opened the boot so the fridge had some outlet for the hot air. Second stop along the highway at Burpengary for some fast food lunch. Then we delivered Erin and Isaiah to their accommodation in Brisbane before their flight back to Airlie Beach tomorrow.

Renting a Tesla Model 3 in Sydney
November 10-11. After surviving the long flight back from Europe two days ago, I hopped back on a plane, from Melbourne to Sydney. Crazy, right! At Sydney Airport, I rented a Tesla Model 3, similar to ours, for a couple of days. Pretty seamless process, except for the web page directions to find the pick up spot at the airport. I could add my own profile to the in car list of drivers, and manually adjust to my preferred settings (such as seat position). But they didn’t give me access to connect my iPhone’s Tesla app. I increasingly missed the app connect features such as automatic lock/unlock and remote climate control. I had to tap the Tesla card to get into the car each time, like a Neanderthal 😉. Out of all the portals through which I could rent it, it turned out to be cheapest to rent through the Uber app, which now also lists car rentals. Go figure.

The food and service on Singapore AIRLINES was great. The in flight wifi is good, but connecting to it is more complicated than it should be. We couldn’t sleep. Towards the end, we looked at each other in despair and lamented “the human body was not designed to endure this”. Final leg from Melbourne Airport to home in Emerald via Uber in a Tesla Model 3, just like ours. We were impressed how the driver managed to fit all our luggage in the boot. Just in time for a well earned sleep 😴. Next morning: removal of the Europe road trip beard.
