Error #5 Temperature Protection

Occurs if the internal temperature of the inverter is outside of the operation range; operation will automatically be stopped.

Operating Temperature (Internal)

-40 ~ + 90°C (-40 ~ +194°F)

Check that the operational ambient temperature is within the operational range.

If the ambient temperature is above 65°C (145°F), the internal temperature of the micro inverter may exceed 90°C (194°F).

Operation will resume automatically when the ambient temperature returns within the operational range.

Alert GFDI

Occurs if the system current leakage exceeds the limit.

Check for other error messages.

In case of a GFDI error, the system will automatically reset within 1 minute.

If problem persists, check all connections.

Check that the wirings status is ok. The insulators (or jackets) of the cables may be worn out or cut.

What is GFDI(Ground Fault Detector/Interrupter)?

Ground fault is when currents flowing through the cable leak through an exposed conductor and touches the ground. The GFDI(Ground Fault Detector/Interrupter) function detects events of ground fault and automatically stops operation of the AC module.
