Fault Type Cause
Automatic Internal temperature is
over 105 °C.
AC input voltage may be
too high while charging.
Operating too large of a
load for too long while
inverting.
Ambient temperature
may be high.
Inverter cooling fan may
have failed.
Inverter airflow intake
may be blocked.
Charging setting is too
high based on ambient
temperature around
inverter.
Automatic See F57.
Manual Auto-configuration
process failed.
Escalating Excessive load on the
Auto Fault. AC output.
Must occur 3
times in 5
minutes before
becoming a
manual fault.
Escalating Excessive load on the
Auto Fault. AC output.
Must occur 3
times in 5
minutes before
becoming a
manual fault.
Solution
Fault clears when temperature drops
to 75 °C.
Check for high input AC voltage.
Remove excessive loads.
Let inverter cool down and try
restarting.
Hold a piece of paper to inverter
vents to check the fan. If the fan has
failed, have the inverter serviced.
Increase clearance around the
inverter or unclog the fan air intake.
Lower the Max Charge Rate
setting.
See F57.
Retry the "Copy From?" procedure,
or configure the unit manually.
Check for loads above the inverter's
capacity. Turn off some loads if
necessary.
