Inverter shutting down evey day do to high battery voltage

Post by drawthow »

I have just upgraded to lithium batteries and flashed the firmware on my system. Now almost every day around the time my batteries are fully charged (12pm) my inverter shuts off and I get these types of errors "Inverter on port 1 has detected a Battery Voltage Sensor Failure ." Yesterday I charged from a generator and same thing happened.

My batteries are 2 48V HSKY LiFePO4 - 103Ah - 5.3kWh

Charging info from manufacture

I have dropped my charging down to 58.4 trying to stop the cutout with no help.

Big Battery units? I find their charging parameters suspect. 58.4 is a very high terminal voltage for a 48V nominal LiFePo4 battery. Also, how can the putative maximum charge voltage equal the high battery cutoff voltage?

I'd check with them about realistic charging parameters, IMO, the doc in the OP isn't it.

By comparison, SimpliPhi specifies a charge voltage of 56.4V and they are very stable.
