Hello, after two weeks off i turned on the inverter Multiplus 3000 to find no power after 10 minutes. The flow and bulk yellow lights were flashing. I reseted the pylontech battery and the inverter but it kept on happening. I checked the error codes of the manual but none really define the problem. The battery shows its full but the inverter switch out after 10 minutes everytime and the yellow lights on the charger side of the inverter come back blinking. I need help to understand if the problem comes from the battery or the inverter. thank you
