To determine the cause of an inverter error condition, refer to the troubleshooting
solutions below to resolve the situation.
Possible cause
Unit was turned off using On/Off button
on front panel.
DC voltage on the inverter's DC
terminals is incorrect.
Excessive load on output.
Unit is in over-temperature protection
and needs to cool down.
Remote Power Off signal is present.
Open AC output breakers or fuses and
bad output wire connections.
AC load too small for Search Mode
circuit to detect.
Inverter Troubleshooting
Solution
Turn the unit on again.
Check the battery voltage, fuses or breakers
and DC cable connections to the inverter. If
the DC voltage on the inverter's DC
terminals is correct, have unit serviced.
Reduce loads.
Turn inverter off and allow the unit to cool
and increase ventilation.
Release or reset the Remote Power Off
switch.
Check the Load VAC status on the System
Control Panel Meters screen and check AC
voltage on the inverter AC Out terminal
block.
If the Meters screen shows correct AC
voltage but there is no AC voltage on the
inverter AC Out terminal block, check for
loose connections on the inverter terminal
block. If connections are not loose, the
inverter may need to be serviced.
If there is correct AC voltage on the Meters
screen and on the inverter AC terminal block,
check for open AC output breakers or fuses
and bad output wire connections.
If AC voltage on the Meters screen or
inverter AC terminal block is incorrect, have
unit serviced.
Reduce Search Watts setting, increase load
above Search Watts setting, or turn off
Search Mode on the Setup menu.
If the AC1 LED is on, check inverter output
connections and voltage.
