 Low Battery - The inverter will shut off whenever the battery voltage falls to the LBCO
(Low Battery Cut Out) level to protect the batteries from being over-discharged. After the
inverter has reached the LBCO level and turned off, the inverter will automatically restart
after one of the following conditions:
o AC Power is applied and the inverter begins operating as a battery charger.
o Battery voltage rises to the LBCI (Low Battery Cut In) level.
 High Battery - In the event the battery voltage approaches the HBCO (High Battery Cut
Out) level, the inverter will automatically shut down to prevent the inverter from supplying
unregulated AC output voltage. The inverter’s status LED turns off when a high battery
fault condition occurs. The inverter will automatically restart when the battery falls to the
HBCI (High Battery Cut In) level.
*High battery voltage may be caused by excessive or unregulated voltage from the solar panels
or other external charging sources
