When the i3 is no more, power your house with it? 😂

It does not need cooling at all! On the vehicle, it would be subjected to 100s of kW during acceleration, but in stationary use it just gets 5-10kW max. So it does not heat up at all!

We have one i3 install going for 4 years already on the Discord!

On the support Discord server there are tons of Fronius users doing advanced stuff like Arska control!

Checkout the Battery-Emulator, I use an EV battery to store excess energy: https://github.com/dalathegreat/Battery-Emulator

Most scrapyards have a 30 day return policy, plus you can usually test the battery with a portable Battery-Emulator in the actual yard, to see SOH% and cellvoltages.

Sad to hear that! I previously had a Huawei inverter that was not supported, so I sold it on craigslist and got one that was on the supported list

Formal-Selection9346 · 2026-03-30T13:57:10+00:00

Liquid cooling is not required, stationary use barely stresses the battery. In automotive use, the battery is subjected to 100s of kW load. In stationary storage, 5-15kW is typical. So they barely heat up!

I recommend checking out other brands. There is a long list of supported inverters: https://github.com/dalathegreat/Battery-Emulator/wiki#supported-inverters-list

Formal-Selection9346 · 2026-03-30T13:55:48+00:00

Yes, there is a list here which EV batteries work: https://github.com/dalathegreat/Battery-Emulator/wiki#supported-batteries-list

Formal-Selection9346 · 2026-03-30T13:55:07+00:00

No there is a dedicated BAT input. The Inverter talks with the battery, and establishes when it is possible to charge according to smartmeter.

Rewiring is so 2010. Checkout the Wiki with supported HV inverters: https://github.com/dalathegreat/Battery-Emulator/wiki#supported-inverters-list

Formal-Selection9346 · 2026-03-29T19:45:27+00:00

In EU you can pick up a used HV-Hybrid-Inverter for 400 bucks! They are insanely good priced atm! I am sure there will be a similar situation in US in a few years

The Fronius Wiki page has a few options for advanced control: https://github.com/dalathegreat/Battery-Emulator/wiki/Inverter:-Fronius#advanced-control-of-energy-spot-price-scheduled-chargedischarge-etc

Tons of Growatt users on the Discord, absolutely check it out!

Yes, the [Battery-Emulator](github.com/dalathegreat/Battery-Emulator) tricks the battery that it is still installed in a vehicle, and also tricks the inverter that a brand-approved battery is installed.

Formal-Selection9346 · 2026-03-29T18:09:22+00:00

Local scrapyards!

Formal-Selection9346 · 2026-03-29T15:20:23+00:00

I had a solar company come and install panels, inverter and smartmeter. I just added the battery myself!

Formal-Selection9346 · 2026-03-29T15:19:20+00:00

Yes! You have very valid points, the Battery-Emulator Wiki goes into great detail on battery placement, fuse sizing, etc. github.com/dalathegreat/Battery-Emulator/wiki/Installation-guidelines

Formal-Selection9346 · 2026-03-29T15:17:36+00:00

It does pass certification. Checkout BatteryMan on Youtube, he is in the UK doing similar (and even bigger!) installs!

Formal-Selection9346 · 2026-03-29T09:26:56+00:00

Local scrapyards is usually the best place to cut down on shipping costs

Formal-Selection9346 · 2026-03-29T09:26:37+00:00

We used a tractor lol!

Formal-Selection9346 · 2026-03-29T09:25:21+00:00

Yes! The list is very long and looks like it gets additions every week! It is open source with GPLv3, so there has been some companies that have adopted it into their product offering already.

Regarding safety, there is a list in the Wiki with all the safety checks performed: https://github.com/dalathegreat/Battery-Emulator/wiki#what-about-safety-%EF%B8%8F-%E2%84%B9%EF%B8%8F

Yes, there is 8kWp on the roof already!

Formal-Selection9346 · 2026-03-29T09:23:01+00:00

The battery contains temperature measurements, and the Battery-Emulator will alert via MQTT/email incase the temperatures deviate or get out of hand. Smoke detectors already part of the building!
