The IC Series is protected against fault conditions and in normal use it will be rare to see any. If a fault condition does occur, the Inverter/Charger will shut down as a safety measure to protect itself, the battery bank, and the AC loads. The following fault conditions could be the cause of Inverter/Charger shut down:
LOW BATTERY - The IC Series will shut off whenever the battery bank voltage falls to the Low Battery Cut Out (LBCO) level to protect the batteries from being over-discharged. When the Inverter/Charger has reached the LBCO and turned off, the unit will automatically restart when AC shore power is supplied to the AC Input and the battery bank voltage rises above the Low Battery Cut In (LBCI) 12.5 VDC level.
HIGH BATTERY - The IC Series will shut off whenever the battery bank voltage approaches the High Battery Cut Out (HBCO) level, the Inverter/Charger will automatically shut down to prevent unregulated AC output voltage being supplied to the AC loads. The unit will automatically restart when the battery bank voltage falls below the High Battery Cut In (HBCI) 14.5 VDC level.
OVER TEMPERATURE - The IC Series monitors the temperature of several key components within the Inverter/Charger. If these components begin to exceed their safe operating temperature level, the unit will shut down to protect itself. The unit will automatically restart after the unit cools down.
OVERLOAD - When the IC Series is in inverting or AC pass-through mode, the Inverter/Charger monitors the current levels. In the event of a short circuit or an overload condition the unit will shut down. To start operating after this fault, the Inverter/Charger must be turned on using the on/off switch on the unit or remote control once the AC loads are reduced/removed.
INTERNAL FAULT - The IC Series continues to monitor several internal components. If a condition occurs that does not allow normal operation the Inverter/Charger will shut down to protect itself, the battery bank, and the AC loads. To start operating after this fault, the Inverter/Charger must be turned on using the on/off switch on the unit or remote control.
