Growatt ARK 2.5L-A1 batteries with non Growatt charger

[pitboss]

Hello everyone.

I was wondering if anyone successfully utilises the Growatt ARK 2.5L- A1 batteries with a non Growatt charger and if so, what is your setup?

I have an off-grid setup with 8 ARK LV batteries and two Growatt SPF 5000 ES inverters in parallel and would like to move away from these inverters (maybe opt for microinverters and MPPT since I have some issue with shading), but would like to keep the batteries.

And yes, as you guessed I am a total n00b when it come s to solar.

Thanks, Mike

Growatt ARK 2.5L Battery?

I did a quick search for a thread on Growatt's batteries, but came up empty for ARK 2.5L. Are these available in the US? They appear to be 48v 50amp batteries, is that correct? Are the SPF-3000TL LVM or LVM-ES compatible with them? (even the 24v SPF-3000?) No concerns about split phase...

I'm guessing that you can use the battery in "voltage" mode (inverter has charge parameters, and doesn't try to communicate with the battery).

Thanks, that is what I was thinking.

But since Growatt support (from other threads) claims that the batteries are only compatible with Growatt inverters I was wondering if anyone actually tried this.

Thanks again.
