I’m sure I can help but not understanding the full issue. Need some more info but it sounds like you are overcharging the batteries to an over voltage level which would shut them down as well as the inverter. Which Rosen battery do you have as in the model number? Is it 15c or 16c? Is it power wall penlight AA design batteries or lion ups design batteries inside the unit? Which Growatt are you using? How many panels connected to charge controller. Integrated cc or all in one hybrid? Need to start there
