Hi,
Having an issue on two sites where the BMS of the battery is connected, and settings are done according to the application note. I have limited the charge current to 50A and the charge voltage to 55VDC.
MultiPlus-II 5KVA firmware 498 and Cerbo GX firmware V2.92
The screen snip High voltage alarm.PNG
Has any one had this issue and what's the best way to correct.
Kind regards
Chad
What batteries are these?
New lithium batteries and high voltage alarms are common and generally need to be kept on keep charged mode for a few days, or have the CVL limited with DVCC while they balance.
Just noticed the tag that its FW. If it’s the e-tower its all normal.
