Growatt Fault 05 fault: Output short circuit

What it means

Something on the output side shorted, so the inverter cut power. A faulty appliance is the usual culprit.

Likely causes

• Faulty appliance
• Damaged extension lead or plug

What you can safely check

1. Unplug the appliance that was running when it tripped, and any recently added appliances, then restart.
2. 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.
