Figure 5-18, Overtemp Fault

• Overtemp – This fault message indicates the inverter/charger has shut
down because the internal power components (FET's and/or Transformer)
have exceeded their safe temperature operating range. When the unit has
cooled down, it will automatically restart and continue operation.
Remedy: If the fault occurs while inverting, reduce the load on the
inverter; if it occurs while charging, turn down the charge rate. If this
fault happens often, ensure the inverter is not in a hot area, has proper
ventilation, and the cooling fans inside the inverter are working.

Figure 5-19, AC Overload Fault

• AC Overload - This fault message displays when the AC load on the inverter/
charger's output has exceeded the inverters AC current protection limits. If the
overload condition lasts for less than 10 seconds, the unit will, automatically
restart and resume operation. However, if the overload occurs more than 10
seconds, the unit will shut down and require a manual restart.
Remedy: This fault usually occurs because the connected AC loads
are larger than inverter's output capacity, there is a wiring short on
the output or the output, wires are incorrectly wired. Once the AC
loads are reduced, or the output wiring is corrected; the inverter can
be restarted after a manual restart has been accomplished.

Figure 5-21, High Volts AC Fault

• High Volts AC - This fault causes the AC Input to be disabled because
a very high AC voltage (>150 VAC; or >300 volts for Export inverters) has
been detected on the AC input.
Remedy: Remove all AC power from the inverter's AC input for
at least 15 minutes to automatically restart this fault; ensure only
120VAC power is connected to each of the inverter's AC inputs.
