I’d drive a leaf before you decide to buy one. For me they’re not all that inspiring. They’re one of the few cars that can do V2H currently though.
I’d be buying some sort of home battery to go with the system though. I have 3 adult kids and one boyfriend (not mine) living at home in a big house, running all electric. I bought a large SigEnergy battery and inverter, from a good installer, who’s not the cheapest. But it’s powering the house, the pool heater in Summer, and charging the one EV.
If you have any home battery system, you can join a VPP (Virtual Private Power) network, and potentially save a small fortune. I already had 9.25kW solar panels installed nearly 5 years ago, and they paid themselves off in around 4 years. I’ve now had the solar expanded to 15kW, and added a 48kW battery and a 10kW single phase inverter. It already looks like I’ll have it paid off in under 4 years.
If I’d bought a Fox ESS unit, installed by an OK, but competitively priced installer, I could probably have it paid off in closer to 18 months. And that’s just the battery paying off its installation cost with savings in power. I’m also saving in car running costs with cheap to free power for the EV. Which I’m not counting toward paying the home battery off.
If you buy a reasonable brand home battery, you’ll be able to buy a fast DC charger down the track that allows V2H once it’s approved by government agencies, and vehicle manufacturers are producing cars that transfer both ways reasonably quickly.
I considered buying the SigEnergy 22kW DC bidirectional charger for mine, but I’d have had to remove one battery and go down to 40kW. I chose to install the 7kW AC charger for now, and revisit it in 2-3 years when I buy a car that works well with the system. By that time, I’ll have that extra battery paid off, and the price of the DC charger will have dropped further. It started at $10K a year or more ago, and is currently around $4.5K. It will only get cheaper.
Size your solar and battery to optimise your usage, and join the right VPP for your use, and you’ll have all the benefits of the home battery and have it paid off fast.
For me, at the moment, GloBird makes the most sense. Many users will be able to take their power bills all the way down to a little below zero each month. If anyone decides to join them, ask me for a code and we both save $50 off our bills.
If you want to fully charge your car and battery every night, and burn pretty much as much power as you like, or charge more than one EV, OVO is probably the best option, with power between midnight and 6am, at a few cents per kWH.
Anyway, buy the battery now. It’s worth it just to join a VPP. Even if you had virtually no solar. Even better if you have plenty.
Buy the car you want, down the track, when it makes most sense to you, and when it’s all legal and you can properly calculate the costings.
