Not all sub trunks are created equal
Some only fit a licence plate. Some can fit a spare tyre. We’re at the Casey Electric Vehicle Expo. Casey is a council region, near us. The Future Drive Australia EV show was supposed to be running this weekend in Melbourne, but they cancelled it just a few days ago, presumably leaving ticket holders and exhibitors out of pocket with no event. They run a range of car shows, not just EVs. I think they’ve gone bust. I thought the Casey show would not be able to compete. But now, they’re the only show in town. Put on by AEVA Australian Electric Vehicle Association. Lots of EVs. Lots of attendees. Lots of questions. I overheard “I’d like to get an EV but I like to go for a drive [a long way]”. I had to bite my tongue “It’s not an issue. We do it all the time”. And some helpful stands, such as ZECO Energy, to help households to get off gas.

Health danger to kids if we keep using gas
The Eastern Melburnian has written about the health risks of household gas. The story includes a mention of our move off gas here in Emerald, along with our own unflattering photo of Tom. The angle is health rather than cost. It quotes Australian modelling from 2018 that attributed 12.3 per cent of childhood asthma to gas cooking, and a 2013 study that found children in a home with gas cooking were 42 per cent more likely to develop asthma. About 80 per cent of Victorian homes still have gas piped in. https://www.easternmelburnian.com.au/p/kids-asthma-coalition-one-nation-gas-plans

Cheaper than free, to fill the car
Beautiful spring day. Flowers soaking up the sun. Solar panels soaking up the sun, but I’ve switched the solar off. Why did I turn off free fuel for the car? There’s a cheaper option today than free. Say what? There’s so much electricity in the grid, mainly from renewables, that the wholesale price has gone negative, so retailers are actually being paid to use it. Our retailer is Amber Electric, which passes on the wholesale price to us. Right now, they’re paying us up to 9c per kWh to charge the car or run any appliances. Probably less than 5c per kWh on average, over the afternoon. Our house battery is “unfortunately” full from solar yesterday, so we can’t use it to soak up more of the cheaper than free electricity and get paid more. Realistically, we’re not going to get rich from this. We might make a few dollars today. But getting paid a few dollars to refuel the car is better than paying $100 for petrol.

The grid went out and the car kept charging
I happened to see AusNet's email this morning — a possible outage in our street. Then I noticed an alert from our Tesla Powerwall, to say it was running off grid. Nothing in the house had missed a beat. Every appliance had kept running without a hiccup. I tapped into the app to see how it was going. The solar was still funnelling through our system, charging the car up from its 60% low after yesterday's run into the city. Once the car was full, the leftover topped up our Powerwall batteries. When you install a battery and solar, get it in writing that in a grid outage the battery will still charge from solar. It is one of the things on my list of what to ask for in a battery installation. I suspect the outage was caused by a tree on a power line, given how windy it is today, up in the hills. This one only lasted a bit over an hour, unlike others that have gone on for up to nine days, taking out streets of homes, shops and the local petrol station. And then, just as I posted this, a…

A month of cooking on induction
We have cooked on gas and on electric elements for years. This is our first month with a Westinghouse full induction cooktop in place of the gas. We had trialled induction on a small scale first. We bought a portable hotplate last year (also Westinghouse), as a spare in our kitchen — on the bench at home, and in the back of the car on road trips. Induction still gets confused with the electric cooking most people remember, a metal hotplate or a coil glowing red, sometimes under glass. Induction works differently — it makes the pan itself the heating element, so nearly all the energy goes into the pan rather than into the kitchen, and the glass beside the pan stays cool enough to rest a hand on. Here is what a month of it has been like. What stands out is how fast and how responsive it is. It comes on instantly, goes off instantly, and changes power the moment you ask. It boils faster than the gas did. CHOICE's testing has induction boiling a litre of water in about half the time gas…

Did going all-electric cause our mould?
We spent 2025 and 2026 getting off gas — heat pump hot water, a multi-head air conditioner replacing the ducted gas heater, and finally an induction cooker. Then we found mould on the bed slats. Was it due to electrification? We first found this same mould, on these same slats, in December 2024 — fourteen months before the air conditioners went in, while the gas ducted heater was still doing all the heating. Whatever causes it was here first, and it was here while the gas was. Gas cooking turns out to actually make it worse. Burning gas makes water: roughly 1.6 kilograms of water vapour for every cubic metre burnt. That is on top of the water coming out of the food or boiling water, which happens whatever you cook on. Going induction removed the extra moisture. Not to mention the benzene, which is a known carcinogen. What did change is the ventilation. The old ducted system leaked, and those leaks quietly brought in outside air. Reverse-cycle doesn't leak. Better heating, staler air.…

It wasn't the grid. It was me.
The Tesla app told me the grid was down. The Tesla app was wrong... kind of. It was an overcast morning in a low-solar week, and our Amber Electric app was lit up green: 19¢/kWh, 30% renewables — "really cheap to use energy right now". So, I set the house battery and the Tesla EV to charge together, from grid power, while we waited for the sun. A few minutes in, the phone pinged: "Power lost while charging — Charging stopped, check power source and charging equipment." The Tesla home view confirmed it — "Grid Outage. Powerwall is providing backup power. ~3.3 backup hours remaining." I checked our circuit board. Nothing tripped. Went online to AusNet's outage page — nothing reported anywhere near us. Their fault-finder asked if the meter display was lit and we'd paid the bill: yes, and yes. Verdict: "It looks like there might be a fault on your property. You'll need to contact an electrician." That's when I remembered the other set of breakers — the ones inside the Tesla Backup…

Adding a second battery — Tesla finally makes it possible
When Lightning Energy installed our Powerwall 2 back in December 2023 it was great. Paired with our 12 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…

Goodbye gas — disconnecting the ducted heating
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. 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. 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. They both needed electricity to run. In fact, in addition the gas consumed, the heating used about 1kW of…

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…

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…

Savic test rides through the Dandenongs
While driving in our town of Emerald to get some Emerald Thai for dinner, I did a double take when I saw a Savic Motorcycles sign, randomly on the footpath. It turns out that they were running test rides today “winding through the beautiful Dandenong Ranges”. What a great idea! Test drives at dealerships and even EV shows tend to be within urban sprawls, which doesn’t offer much of a driving or riding experience. We’ve seen Savic at a few EV shows, including the recent Everything Electric in Melbourne (pictured). I wish I had known it was on, and that we weren’t recovering from a cold right now. Hopefully next time. Savic is an Australian company building electric motorcycles.

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…

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 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.

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.

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.

Some conversions, some plug in hybrid (PHEV), and one large battery swap unit for a semi, in just 3 minutes. We sat in the huge frunk of the F150 Lightning, made possible because no engine is needed. Some electric utes have been popular for mining operations, so as not to poison the air in the shafts, and to avoid the need to truck in fuel to remote sites. On the way out, we spotted a BYD Shark (PHEV) parked at a fast charger on the street. Frustratingly, they hadn’t plugged in. There were a couple of parking cops who were hopefully about to post an infringement notice. Chargers are for charging, not just parking 🤦♂️.
