Hi all

I have a seplos battery connected to a solis inverter (RAI-3K-48ES-5G)
, I use this just to charge overnight then run the house during the day. I do not have PV.

The system has worked flawlessly for 2 years but a few weeks ago just stopped. No alarm messages on the battery or the inverter.

The battery is communicating just fine, the grid and load data is valid. There’s literally nothing that I can see that isn’t working. Solis haven’t been able to help and since it isn’t a recognised battery they aren’t inclined to put much effort in.

Can anyone suggest anything?
