RESOLUTION Owners with impacted year models should follow the Lithionics approved method for the proper restart/reboot sequence of the batteries and inverter to ensure all batteries are ON before turning the inverter ON. NOTE: The inverter is also a charger and when it powers up while connected to shore power this is utilizing the charger side. The above referenced potential condition exists only when the inverter side is turned ON. PROPER RESTART/REBOOT SEQUENCE If the inverter is OFF, drained or has entered (LBCO) Low Battery Cut Off and any or all of the batteries are OFF (no LED light on battery), then the following procedure should be followed: 1. ENSURE THAT THE INVERTER IS TURNED OFF 2. UNDER THE STREET SIDE BED ACCESS PANEL, SWITCH THE INVERTER CIRCUIT BREAKER TO THE OFF POSITION. PRESS THE RED BUTTON Note: This will cause a communication issue for the inverter remote display and requires a proper restart sequence to ensure proper communication between the inverter and remote display.
