Inverter overload: what it means
An overload means your home is asking for more power than the inverter can deliver.
Why it happens
Every inverter has a rated output (for example 5 kW). Kettles, heaters, geysers, ovens and pool pumps can each use 2–3 kW. Switch a few on together during load-shedding and you're over the limit.
What to do
- Switch off or unplug heavy appliances on the backup circuits.
- Run big appliances one at a time.
- Restart the inverter once using its documented procedure if it shut down.
- If it overloads with very little running, call a qualified installer.
Common overload codes
Deye/Sunsynk F34, Growatt and Axpert fault 07 or warning 07 all mean overload. Look them up in our fault-code library for brand-specific advice.
Solar systems carry dangerous voltages. Only do the safe checks listed. If unsure, call a pro.
Common questions
- Can overloading damage my inverter?
- Inverters protect themselves by shutting down, but repeated overloads add stress. Managing your loads is the best fix.
- Should my geyser be on the backup circuit?
- Usually not. Ask your installer about moving heavy loads off the backup circuits.
