W11
AC2 Input L1 Over
Voltage
Automatic
AC Over Voltage Warning
(AC2 Line 1 input is at or
above the AC2 Hi Volt
setting, minus 2 V)
Check AC input voltage. Check or
adjust high AC input voltage
setting (AC2 Hi Volt).
W12
AC2 Input L1 Under
Voltage
Automatic
AC Under Voltage Warning
(AC2 Line 1 input is at or
below the AC2 Lo Volt
setting, plus 10 V)
Check AC input voltage. Check or
adjust low AC input voltage setting
(AC2 Lo Volt).
W13
AC2 Input L2 Over
Voltage
Automatic
AC Over Voltage Warning
(AC2 Line 2 input is at or
above the AC2 Hi Volt
setting, minus 2 V)
Check AC input voltage. Check or
adjust high AC input voltage
setting (AC2 Hi Volt).
W14
AC2 Input L2 Under
Voltage
Automatic
AC Under Voltage Warning
(AC2 Line 2 input is at or
below the AC2 Lo Volt
setting, plus 10 V)
Check AC input voltage. Check or
adjust low AC input voltage setting
(AC2 Lo Volt).
W44
Battery Over
Temperature
Automatic
Battery Over Temperature
Warning. Battery
temperature is over 50 °C.
Check battery voltage and battery
cable connections. Stop charging,
if necessary. Check for excessive
ambient temperature and adequate
ventilation in the battery
compartment
W45
Capacitor over
temperature
Automatic
DC Bulk Capacitor over
temperature (100 °C)
Ensure adequate ventilation around
the XW Inverter/Charger. Reduce
the AC loads.
W48
DC Under Voltage
Automatic
Battery voltage is below
46 V.
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.
W49
DC Over Voltage
Automatic
Battery voltage is above
68 V.
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.
