I have a Luxpower5000 Inverter connected to Freedom Won Battery which has just been repaid and firmware updated. Now, it won`t allow the grid to charge the battery when the battery requires it. When the battery has rundown, the grid just supplies power to the house instead of supplying the house and battery at the same time. The communication cable is correct and the dip switches are also correct. Is it just a setting on the inverter I need to change? Can Anybody help?
