Problem
Possible Cause
Solution
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.
No output voltage. The Status LED is green or
yellow.
GFCI has tripped or 15A supplementary
breaker has tripped.
Check load and reset the GFCI or supplementary breaker.
Circuit breaker on the AC load panel or
AC output disconnect has tripped.
Reset the circuit breaker or check the AC output disconnect
circuits.
Battery voltage is too low (depending on
setting, see
)
to start inverting. Display screen may
show DC voltage as
00.0
.
Check DC connections and cable.
Recharge battery.
