Problem Possible Cause Solution
No output voltage. The status LED is red. AC shore power isnot 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)
• Verifythe unit isconnected to a 12V battery.
• Check the voltage regulation of the externalcharging system (if
any).
Unit overload or AC output short circuit
(fault code E03)
• Reduce the load. Make sure the load doesnot 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’sventilation openings
are not blocked.
AC transfer relay has overheated (during
shore power mode).
• Improve ventilation. Make sure the inverter’sventilation grille is
not blocked.
• Reduce the load.
No output voltage. The Status LED is green or
yellow.
GFCI hastripped or 15A supplementary
breaker has tripped.
Check load and reset the GFCI or supplementary breaker.
Circuit breaker on the AC load panelor
AC output disconnect has tripped.
Reset the circuit breaker or check the AC output disconnect
circuits.
Battery voltage istoo low (depending on
setting, see Operating Limits on page 35)
to start inverting. Display screen may
show DC voltage as 00.0.
Check DC connections and cable.
Recharge battery.
