System has been installed 3 weeks for client with multiple shut downs that needed manual restart. First it gave low voltage alarm at 49 volt resulting in shut down and error 17. I lowered my shit down voltage to 46V and SOC is set at 65 % minimum.
Last 2 days in a row in the middle of the day i am getting overload alarms with system drawing just about no power and batteries being charged from PV.
