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…

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…

Why ducted air conditioning is inefficient
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…

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…

A surprise picnic by the Yarra River
Surprise picnic. Making use of all the hidey-holes in the Tesla. Let’s pull over here next to the Yarra River. Would you like a cold drink? I just happen have a powered fridge in the sub trunk of the car. We can sit on the camp chairs from the frunk (front trunk, since there’s no engine). How about a cheese platter and some cherries to go with it? Ok “platter” is a bit of an overstatement, but work with me here. The car also has kitchen utensils and a dining table. We might as well just stay here for lunch now.

Fast charging at the Bairnsdale Superchargers
It's conveniently located close to shops, near the centre of town, but it's right next to the entry of a very busy car park. There are only three charging spots. I watched another Tesla try a few times to reverse into a charger from a park opposite. Fortunately, other waiting drivers kept their holiday cheer. I tapped on the window and asked if they'd like me to park the car for them. She explained that it was her husband's car, who had apparently gone to the shops. She seemed very relieved to hand over control to someone familiar with the car. I parked it and plugged it in. After that and a cuppa, the car was charged up enough to take me all the way home. I had to do a slight three point turn to exit the car park when I was done. Did I mentioned it's a slightly awkward spot?

Bonang Road brought back my motorcycle days
Harkening back to my motorcycle days, enjoying the endless curves along the Bonang Road from Tubbut to Orbost, Victoria, leaving the Snowy Mountains. The Tesla handled the drive beautifully. FSD off, for some driving fun. I had to watch out for quite a few sharp dips, barely marked with crayon width paint on the road. This road has stopping spaces specifically for motorcycles (pictured). Yesterday, I grabbed some groceries in Bombala and noticed the "Welcomes Motorcyclists" sign. Before we bought our first EV in 2022, we did a lot of motorcycle road trips. As you can see from the photos from a decade ago, we haven't aged at all! 😉. I'd love to see some "Welcomes EVs" signs in regional places. My stay last night in Tubbut was thanks, in part, to the simple EV changer provided by Gippsland Climate Change Network. They are on to something!

Creekside car camping in the Snowy Mountains
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…

The best rest stop in the middle of nowhere
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.

No petrol in Dalgety, but plenty of power points
No petrol, no worries. The small town of Dalgety has no working petrol station. The last working bowser I passed yesterday was about 50km away in Cooma, along with the nearest fast EV charger. But Dalgety does have hundreds of power points, including the powered camp sites at Snowy River Holiday Park. I could have used any one of them to fill up my car. It’s a beautiful spot. I car camped there last night. This morning, I pushed the Teraglide kitchen drawer back in, pressed the Deflate button on my Snuuzu mattress, flipped back the top (pictured), and moved the drivers seat back into my preferred position by hitting the Restore button in the Tesla. Super quick transformation, ready to drive on to the next camp site today.

I wish my Model Y had V2L
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…

Good morning! Time for breakfast, after a great night’s sleep in the Tesla. “Siri, open Tesla boot”. The tailgate opens to reveal a beautiful day, beyond my bare feet. Breakfast mode: 1. Pull out the Teraglide drawer and table. 2. Flip open the Teraglide rear lid. It’s assisted by gas struts, so it’s easy to lift and stays up, even with bedding on top of it. 3. Open the fridge in the subtrunk to get brekky supplies. This morning, that’s eggs, butter and milk. 4. Use the kitchen drawer bits to crack and whisk the eggs, add milk, soak some bread, ready to make French toast. 5. Stroll over to the camp kitchen. Fry the toast and boil some water for my thermos. Return to the Tesla. Enjoy my French toast, with a cuppa tea, overlooking the Snowy River. Nice.

Photo op in Bredbo, campsite hunt in Cooma
Photo op in Bredbo, before stopping in Cooma to figure out where to camp tonight. On the way, I used the Tesla’s navigation to search for “campground” and similar. One option was The NRMA park in Jindabyne. I tapped the phone icon, to make a call. Handy to do it all from the car’s controls. Unfortunately, all their powered and unpowered sites were booked for tonight. This looked like a job for WikiCamps. Since Tesla doesn’t support Apple CarPlay, I needed to pull over to use my phone. Whenever parking, I aim to charge, so I don’t lose any time. So, I pulled into the new-ish Tesla Superchargers in Cooma. This is the second site in Cooma, with more chargers and faster speed. But the only service nearby seemed to be KFC (again 🤔). No matter, I just wanted time to access my phone. Snowy River Holiday Park looks great. I rang them, gave them my ETA, entered it into the navigation, added Cooma Coles as the first destination, so I could grab some supplies. Cooma Coles also has Tesla…

Great chargers, sad site, at Coolac
Time for a break and a cup of tea. The navigation says that the next EV charger is at Coolac, just north of Gundagai, so we stopped there. Wow. It’s a pretty bad. The chargers are great, simple and fast. But the site is woeful. The hotel is closed or being renovated. The toilets are port-a-loos, but are disgusting . I don’t know how much of that is due to infrequent maintenance versus just being the busiest time of year. There is a service station nearby with some food and hopefully better toilets, but it’s a ten minute walk away in the heat, and not an option for Mum’s walker. Some people were sheltering from the sun under the three tall trees begging the toilets. Not a great spot. Tesla/government really needs to ensure better location for EV chargers. We enjoyed a cup of tea from our thermoses, and some Christmas snacks (thank you Krissy). Some way further up the highway, we pulled over into Bookham, for a conveniently located toilet and a bit of a stretch in some broken shade. In…

Sharing a lamington at the Narooma chargers
There are two ways to tell a story: 1. Embellished: The mayor of Eurobodalla Council came out to welcome us as we rolled into Narooma. 2.

Another Tesla Model Y Juniper pulled up next to us. The driver jumped out, said he recognised our profile as “Tesla Tripping”. He introduced himself as “Matt, the Mayor”. Mathew Hatcher - Mayor Eurobodalla Shire We had a good chat about how the council has been introducing EVs into their fleet.

Emerald to Maffra: praising and grumbling at FSD
First leg on our 4000km journey: Emerald to Maffra, in Gippsland Victoria. The tall trees of our Dandenong Ranges gave way to rolling green hills. FSD (Full Self Driving) makes the (non) driving a breeze. One minute I’m singing its praises after it flawlessly indicates and merges into traffic. The next I’m cussing at it for complaining that I was looking at the navigation too long. We stopped in Maffra to grab some lunch, and just made it before small-town-closes-o-clock (2pm), to grab a veg toastie, banana bread and coffee. Next, north, over the alps towards Bright.

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…

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…

What size solar system should I get?
Installing solar is relatively cheap, when you consider that it pays itself off in 3 to 5 years. It will be cheaper overall to install the maximum now, than to try to upsize it in a few years, especially since you will probably only have one chance to get subsidy help. If you have the money or can use one of the government payment schemes, I suggest getting the maximum allowed 10kW system, with slightly more panels (see below). You also need to have enough unshaded roof space to install them. In the southern hemisphere, we aim solar panels to the north for maximum sunlight. A north facing room will produce a high peak of solar power in the middle of the day, when your demand is probably low. So, it’s typically best to place panels on east and west (or north east and north west) facing roofs to skew power to the beginning and end of the day, respectively. On our house, we have all of our panels on a north west facing roof. This skews our production slightly to the end of the day, but…

Solar, battery and electrification — series intro
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…

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…

An impassable bridge, a beautiful walk near Kurth Kiln
Not all routes are equal. We took the slightly longer map option to Kurth Kiln National Park, expecting we could take the shorter route home. But, no, some bridges are impassable. We randomly picked this spot for a walk, using the AllTrails app. It allows us to filter difficulty, duration, distance away, elevation, and monitor our walk along the way, even with no Internet connection in the bush. The information boards included the history of charcoal fuel production here, and the hurdles for vehicle drivers to overcome new fuel types, like petrol 😉. FSD (Full Self Driving) took us along the windy country roads without an issue, until the motorbikes behind our car brought out the biker in me. I switched to human driving, to push the bends more than the overly cautious FSD.

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.

Last overnight stop, in Sea Lake
Part way through one of the Silo Art trails, yesterday, the sun was setting, so we booked a room at the next town, at the Sea Lake Motel. This is our final overnight stop before driving the remaining 450km to home, today. Last night, almost everything in this small town was closed. The motel stocks refrigerated meals in a vending machine, for people like us stopping in at the last minute. Great idea. We chose a curry, microwaved it in our room, but then realised that the used by date on the two packets was months ago, even though the used by date on the outer packet was fine. We decided not to risk it, and happily made a picnic tea out of our car travel food. We informed the host, just so they knew. It’s the fault of the food company, not the host.

One of the other visitors had just driven from WA, and asked where the next petrol station was. I laughed and told him that of all the people he could have asked, I was probably the least suitable, driving an electric car. But I happened to know that there is one back at Yulara, about 40km away. He seemed relieved that was less than the fuel range he had remaining. We discussed the high cost of fuel out here, at around $3 per litre. He asked about our electric car. I mentioned that I’d noticed that the toilet block in the car park had a power point, next to the hand dryer. In an emergency, I could probably use that, powered by the solar on the roof and I think backup diesel generator.…

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.…

Charging at the centre of the centre of Australia
Charging our EV in "the centre of the centre of Australia". After driving 1500km north along the Stuart Highway, we reached “the centre of the centre of Australia”., with a turn left/west towards Yulara and Uluru. First we stopped at the intersection’s Erldunda Roadhouse, in the town of Ghan (well, that’s all there is in Ghan). We grabbed some lunch, laughed at the banners for sale, and visited the emus. No cell reception for our Belong phone SIMs (which it seems doesn’t quite give us the whole Telstra network), so we made use of the free wifi. Petrol here is about a dollar per litre more expensive (about 50%) 😮. The fast charger is also about 50% more expensive than typical. At the EV charging station, we chatted to Jigar. He bought his EV in Darwin, then later started working at Uluru and I think Alice Springs. This charger is perfectly positioned for EVs passing through.

Sharing the Stuart Highway with a solar-powered prototype
So, there we were, cruising along the Stuart Highway, in outback Australia, feeling like pioneers in our electric vehicle. Then we came across true pioneers, driving a solar powered prototype car. They were practicing for the Bridgestone World Solar Challenge, which runs from Darwin to Adelaide. They told us that they are only allowed to practice in South Australia, and not in the Northern Territory, so they had to travel south this far for a few weeks, then go all the way back to the start of the race. We ran into a few teams, including support vehicles with a StarLink dish on the roof, along the way, from various countries and universities. It seems that they test during the day, then typically set up camp overnight just off the highway. Big commitment to spend a few weeks in the Australian outback. Thank you for your research and development that filters through to a more sustainable future for transport.

Wind and solar farms south of Port Augusta
Just south of Port Augusta, we passed another wind and solar farm, generating power for local communities. No noise, smell, or breathing hazards. Of course, it would be great if we could avoid any environmental impact. But this is way better than a giant coal mine and power station, or oil drilling.

A waterfront picnic in Port Pirie
Arrived in Port Pirie, on our way north to Uluru. Most lunch outlets were closing, so we had a “picnic lunch” from our car fridge and food bag, by the waterfront. The giant silos backdropped the inlet with the wharf, bridge and black swans. The southern Flinders ranges in the distance might be the last mountains we see for a while. We stayed at the Comfort Inn. Basic continental breakfast included, at the on site Serenity Restaurant. Simple hot options also available.
