Growatt Fault 02 fault: Over-temperature

What it means

The inverter is running too hot inside and will reduce power or shut down to protect itself. Better airflow and a cooler spot usually solve it.

Likely causes

• Blocked vents
• Hot room or direct sun on the unit
• Heavy loads on a hot day

What you can safely check

1. Make sure the vents around the unit are clear and nothing is stacked against it.
2. Check the room or garage temperature and improve shade or ventilation if it is very hot.
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.
