Your inverter plays a vital role in converting solar energy into usable power for your home. When it stops working, your panels can’t send electricity to your home or the grid — meaning lost savings and lost energy.
Here’s how to identify what’s wrong and when to call a professional.
Common Causes of Inverter Failure
1. Grid Voltage Fluctuations
Surges or unstable grid voltage can trigger inverter shutdowns. These safety cut-offs prevent damage but require professional resetting.
2. Overheating
Inverters placed in direct sun or unventilated spaces can overheat and shut down. Relocation or shade protection can solve this issue.
3. Faulty Components
Internal capacitors or boards may degrade over time, especially in older units.
4. Moisture Ingress
Exposure to rain or humidity can corrode internal components, especially if seals have worn out.
How to Check for Faults
- Look for flashing red or orange lights on your inverter.
- Check the display screen for fault codes.
- Compare system output via your energy app or inverter portal.
