Troubleshooting
Tripped GFCI Outlet
If an amber light is displayed on the GFCI outlet, disconnect all loads, then press the reset button. Note: output power must
be ON for the test or reset button to function.
Display Fault Codes
The following Fault codes are provided on digital display when system Fault/Warning occurs:
E01
DC Input Under-Voltage Shutdown. Unit is detecting an input DC voltage which is too low and it is shutting down. This fault
can be caused by a discharged or undersized battery. Incorrect DC wiring length and gauge or fault DC connection can also
cause this fault.
E02
DC Input Over-Voltage Shutdown. This fault could be due to a problem in the vehicle charging system. Unit will resume
normal operation when voltage returns to the allowed input voltage range.
E03
Inverter Output Overload (or Short Circuit) Shutdown. Unit is being severely overloaded. Reduce the load.
If this fault occurs in shore power mode the unit must be reset. To reset, remove AC loads and turn inverter power off and
on.
E04
Inverter Over-Temperature Shutdown. Unit is shutting down to protect itself from thermal damage. Place the unit in a location
with lower ambient temperature or improve air flow around the unit.
E05
DC Input Under-Voltage Warning. Unit is detecting an input DC voltage which is too low and it is warning the user that it will
shut down within 10 seconds. This fault can be caused by a discharged or undersized battery. Incorrect DC wiring length and
gauge can also cause this fault.
E06
Inverter Output Overload Warning. Inverter is detecting an overload and it is warning that it is going to shut down within 10
seconds. Reduce load and inverter will keep operating normally.
E07
Inverter Over-Temperature Warning. Inverter is approaching its maximum operating temperature and it will shut down within
10 seconds. Reduce load or/and move the inverter to a location with lower ambient temperature or better air flow.
E08/E09
Not used
E10
Charger Output Over Voltage Shutdown. Battery charger has detected a battery voltage above normal operating range.
Vehicle charging system may be damaged.
E11
Battery not accepting charge. Inverter is trying to charge the battery, but battery voltage is not increasing over time. Battery
may be damaged
E12
Transfer Relay Over-Temperature Shutdown. Relay that switches inverter to shore power mode is running at an unusually high
temperature and unit it is shutting down to protect itself. This could be due to an overload condition in shore power mode.
Reduce the load and unit will return to normal operation
