Axpert Warning 07 warning: Overload
Safe to check yourself
Urgency: low
What it means
You're using more power than the inverter is rated for. Switch some appliances off.
Likely causes
- Too many appliances at once
What you can safely check
- Switch off or unplug heavy appliances (kettle, heater, geyser, pool pump) on the backup circuits.
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.
