Problem Possible Cause Solution
Low output voltage
(96 Vac–104 Vac) during
Inverter mode.
You are using a voltmeter
that cannot accurately
read the RMS voltage of a
modified sine wave.
Use a true RMS reading voltmeter such as
the Fluke 87.
No output voltage. The status
LED is red. AC shore power is not available or out of operating range and the
inverter has shut down with the display screen showing one of the
following error codes:
• Low input voltage
(fault code E01)• Check the DC connections and the
cable.
• Recharge the battery.
• High input voltage
(fault code E02)• Verify the unit is connected to a 12V
battery.
• Check the voltage regulation of the
external charging system (if any).
• Unit overload or AC
output short circuit
(fault code E03)
• Reduce the load. Make sure the load
does not exceed the output rating.
• Thermal shutdown
(fault code E04)• Allow the unit to cool off.
• Reduce the load if continuous
operation is required.
• Improve ventilation. Make sure the
inverter’s ventilation openings are not
blocked.
• AC transfer relay has
overheated (during
shore power mode).
• Improve ventilation. Make sure the
inverter’s ventilation grille is not
blocked.
• Reduce the load.
