u/UnacceptableUse

I've just moved from a GivEnergy system to a Sigen Hybrid 5.0 SP2. Everything was fine for the first day but on the second day I got an over voltage warning. After that, the over voltage warning went away but the battery and solar now act erratically.

The battery mostly refuses to do anything, sitting at 100% and not covering any load. If I command discharge it will discharge at a maximum of 32W. Occasionally it will work, sometimes covering the full load but sometimes only covering ~1kW.

The solar sits at 0W most of the day, when it's sunny it will get up to 1kW or so but that's only a quarter of what my array should be making. Occasionally it will generate the full amount but then only put it into the battery without covering any of the load.

All the time this is happening there are no alarms, and the app diagnosis says there are no problems. I do have predbat setup but all the problems I describe happen without predbat running and out of external EMS mode.

Any ideas? Is this a fault with the unit?
