5.0 Operation
Overtemp
– This fault message indicates the inverter/charger has shut
down because the internal power components (FETs 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.
AC Overload
- This fault message displays when the AC load on the inverter/
charger’s output has exceeded the inverter’s 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 for more than 10
seconds, the unit will shut down and require a manual restart.
Remedy:
This fault 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 installed. Once
the AC loads are reduced or the output wiring is corrected, the
inverter can be restarted after a manual restart.
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.
