5.0 Operation
• DC Overload Fault – The inverter shuts down to protect internal power
components from an excessive AC load. If the overload condition lasts for
less than 10 seconds, the unit automatically restarts and resumes operation.
However, if the overcurrent condition occurs for more than 10 seconds, the unit
shuts down and requires a manual restart.
Remedy: This fault occurs because: the connected AC loads ex-
ceed 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. If this fault continues after all these recommendations,
perform an inverter reset (see Section 6.2).

What if the cable is not the issue?
•
Try another remote display.
• Disconnect the remote from the Remote port and connect to the Net-
work port.
• The inverter might need servicing.

• Overtemp Fault – The inverter/charger has shut down because the
internal power components (FETs and/or transformer) have exceeded their
safe temperature operating range. Once the unit cools down it automatically
restarts and continues 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.
