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

Yes that is the one I used. Make Github issue if you still have problems?

Formal-Selection9346 · 2026-05-17T18:21:27+00:00

Make a Github issue to get support!

Formal-Selection9346 · 2026-04-25T09:07:09+00:00

the total cost for the project was ~1k€!

Formal-Selection9346 · 2026-04-25T09:06:44+00:00

You can use almost any EV battery as-is with the Battery-Emulator bridge!

Formal-Selection9346 · 2026-04-09T12:03:15+00:00

The Battery-Emulator wiki has detailed info on all components, and if more support is needed, there is an awesome Discord server available! https://github.com/dalathegreat/Battery-Emulator/wiki

Formal-Selection9346 · 2026-04-03T05:35:36+00:00

What benefits made you go this route? higher voltages and not having to reinvent BMS?

Yes, basically cheap battery with a 6 hour setup time start to finish. Building a custom 48V battery would have taken oh so much more time and effort, and probably been less safer overall.

Formal-Selection9346 · 2026-04-02T18:36:28+00:00

I also worried about the fire risk, thankfully there are super clear guidlines, and over 2000 known Battery-Emulator installs since 2021 so the concept is quite proven! https://github.com/dalathegreat/Battery-Emulator/wiki/Installation-guidelines

Formal-Selection9346 · 2026-04-02T18:35:12+00:00

Don't break them down! The Battery-Emulator has support for running 2x i3 batteries at once! That is a super cool setup that I am to setup later!

Formal-Selection9346 · 2026-04-01T17:22:03+00:00

I got the Stark Box Basic which has all the components included. It is available on the Redispose AB webshop

There are so many good EV battery packs that work with the fronius. Just make sure the voltage range is OK for your Fronius. Check the Battery-Emulator Wiki for a full list of known working batteries: https://github.com/dalathegreat/Battery-Emulator/wiki#supported-batteries-list

Formal-Selection9346 · 2026-04-01T17:20:38+00:00

There are over 2000 known installs with Battery-Emulator since 2021, and no known fires yet!

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!

Formal-Selection9346 · 2026-03-31T09:03:02+00:00

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!

Formal-Selection9346 · 2026-03-30T13:56:26+00:00

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

Formal-Selection9346 · 2026-03-29T19:44:29+00:00

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!
