Solution
Check AC input voltage. Check or
adjust high AC input voltage
setting (AC2 Hi Volt).
Check AC input voltage. Check or
adjust low AC input voltage setting
(AC2 Lo Volt).
Check AC input voltage. Check or
adjust high AC input voltage
setting (AC2 Hi Volt).
Check AC input voltage. Check or
adjust low AC input voltage setting
(AC2 Lo Volt).
Check battery voltage and battery
cable connections. Stop charging,
if necessary. Check for excessive
ambient temperature and adequate
ventilation in the battery
compartment
Ensure adequate ventilation around
the XW Inverter/Charger. Reduce
the AC loads.
Check for the correct battery
voltage at the inverter's DC input
terminals. Check for an external
DC load on the batteries. Check
condition of batteries and recharge
if possible or reduce your Low Batt
Cut Out setting.
Turn off or check additional
charging sources to batteries.
Check battery cables.
Check for the correct battery
voltage at the inverter's DC input
terminals. Ensure your DC source
is regulated below your high
battery cut out or increase your
High Batt Cut Out setting.
