Growatt Warning 10 warning: Output power derating

Keep an eye on it
Urgency: low

What it means

The inverter is reducing its output, usually because it's hot or solar input is limited.

Likely causes

  • High temperature
  • Limited solar input

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.

When to call a pro

If it doesn't clear on its own, happens often, or comes with burning smells, heat or noise, call a qualified installer.

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