5.0 Operation

• Overtemp – 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.

Overtemp appears on the LCD.

The FAULT (red) LED is on. The

PWR (green), CHG (green), and INV

(green) LEDs are off.

Figure 5-29, Stuck Relay Fault

• Stuck Relay – This fault message displays when the inverter is

“inverting”, but the internal AC pass-thru relay that should be open while

inverting, is closed.

• Overcurrent – This fault shuts down the inverter to protect internal

power components. It may be caused by an excessive AC load. If the overload

condition lasts for less than 10 seconds, the unit will automatically restart

and resume operation. However, if the overcurrent condition occurs for more

than 10 seconds, the unit will shut down and will require a manual restart.

Remedy: This fault usually occurs because the connected AC loads

are larger than the inverter’s output capacity, there is a wiring short

on the AC output, or the wires are incorrectly installed. Once the

AC loads are reduced or the output wiring is corrected, manually

restart the inverter to resume operation. If this fault condition con-

tinues after all these recommendations, perform a inverter reset

(see Section 6.2).
