Axpert Fault 05 fault: Output short circuit or converter over-temperature

Safe to check yourself
Urgency: medium

What it means

Either something on the output shorted, or the inverter's converter got too hot. Remove faulty appliances and improve airflow.

Likely causes

  • Faulty appliance
  • Blocked vents or hot room

What you can safely check

  1. Unplug the appliance that was running when it tripped, and any recently added appliances, then restart.
  2. Make sure the vents around the unit are clear and nothing is stacked against it.
  3. If it keeps coming back, stop and call a qualified installer.

When to call a pro

If the safe checks don't clear it, or it keeps coming back, call a qualified installer.

Solar systems carry dangerous voltages. Only do the safe checks listed. If unsure, call a pro.
