OPERATION
4.9 GP-IC-2000 FAULT CONDITIONS
The GP-IC-2000 is protected against fault conditions and in normal use it will be rare to see any. If a fault condition does occur,
the GP-IC-2000 will shut down as a safety measure to protect itself, the battery bank and the AC loads. The following fault con-
ditions could be the cause of Inverter / Charger shut down;
LOW BATTERY - The GP-IC-2000 will shut off whenever the battery bank voltage falls to the LBCO (Low Battery Cut Out) 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 LBCI
(Low Battery Cut In) 12.5 VDC level
HIGH BATTERY - The GP-IC-2000 will shut off whenever the battery bank voltage approaches the HBCO (High Battery Cut
Out) level the Inverter / Charger will automatically shut down to prevent un-regulated AC output voltage being supplied to the AC
loads. The unit will automatically restart when the battery bank voltage falls below the HBCI (High Battery Cut In) 14.5 VDC level
OVER TEMPERATURE - The GP-IC-2000 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 shutdown to protect itself. The unit will
automatically restart after the unit cools down.
OVERLOAD - When the GP-IC-2000 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 GP-IC-2000 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
4.10 MAINTENANCE AND TROUBLESHOOTING
The GP-IC-2000 is designed to be service-free, even though there are no user serviceable parts, it is recommended that every
6 months you perform the following maintenance steps to ensure optimum performance and extend the life of your batteries.
• Visually inspect the batteries for cracks, leaks or swelling - replace if necessary.
• Use baking soda to clean and remove any electrolyte spills or buildups.
• Check and tighten all battery terminal connections.
• Checkandllbatterywaterlevelsinoodedleadacidbatteries.
• Check individual battery voltages (load test those that have a voltage difference of more than 0.3 VDC from each
other) replace if necessary.
• Check the Inverter / Chargers ventilation vents - clean if necessary.
• Visually inspect all cables in both the DC and AC systems - check for wear/abrasion - replace if necessary and
ensure strain reliefs and cable protection is installed to prevent future damage.
• Check and tighten the Inverter / Chargers AC terminal block connections.
•
Check the ground connections are secure on the Inverter / Charger, Battery Bank, Main / Sub Panels and the
Earth Ground on the RV, Boat.
• Check the battery sensor is still securely attached to the battery bank.
