Inverter Troubleshooting

No AC power output.
The inverter
information panel
displays Sch.
Open AC output breakers or fuses
and bad output wire connections.
Inverter is disabled. Re-enable
inverter.
Check the Load AC Voltage status on
the SCP 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.
No AC power output.
INVERT LED is
flashing.
AC load too small for search mode
circuit to detect.
Reduce Search Watts setting,
increase load above Search Watts
setting, or disable Search on the Setup
menu.
If the AC1 LED is on, check inverter
output connections and voltage.
Low AC power output
or low surge power.
INVERT LED is on.
AC inductive loads
are not running at full
speed.
Insufficient DC current being
provided to the inverter to operate
the AC loads.
Check the battery voltage, fuses or
breakers and cable connections.
Make sure the battery bank is sufficient
(check for low DC voltage while running
the load).
Make sure the cable length and size is
correct (see the Conext XW+ Installation
Guide for correct cable). Tie the battery
cables together to reduce inductance.
Apply a load greater than 100 W or
disable
Power Save (see Table 3-12,
“Advanced Features Menu” on page 3–
47).
