We hear a lot about those solar panels, but it’s the solar inverter that plays just as critical a role in turning the free and green energy from the beautiful sun into usable, ultra-cheap electricity. But what happens when your SolarEdge inverter displays an error code? It’s a highly reputable Israeli renowned for leading the world in smart energy solutions, but that doesn’t mean they aren’t susceptible to the odd problem. Seeing a flashing code? What to do you – panic? Definitely don’t do that, because not all SolarEdge inverter problems require an expert at all! Some can be fixed with simple troubleshooting.
In our exclusive guide, we’ll walk you through:
- What the solar inverter fault codes mean
- Step-by-step fixes for common SolarEdge issues
- When to call Solar Edge tech support vs. a solar repair specialist
If your SolarEdge inverter lights indicate a fault, we’ve tried to include absolutely everything you need to know.
Understanding solar inverter error codes (SolarEdge)
SolarEdge inverters – like most other inverters – use specific error codes to pinpoint problems. Some are minor, while others require urgent professional attention.
How do the codes work?
- Older (pre-3.19xx firmware) inverters display error numbers (like Error #10).
- Newer (post-3.19xx firmware) inverters use error codes (like 8x3B).
- Some codes are specific to single-phase or three-phase inverters.
Knowing what type of error you’re dealing with will help you troubleshoot quickly.
Troubleshooting common SolarEdge inverter errors
Do you know how difficult it would be to write a guide like this if we had to list every single error? We’d never finish, and you’d never read it! So what we’ve done is group them into common problem categories.
1. Communication errors (Inverter Not Reporting Data)
Common Error Codes:
- Error #49 / 8×10 – Communication Error
What To Do:
- Check WiFi/Ethernet connection. If your inverter connects via WiFi, ensure the router is working.
- Reconnect the inverter to SolarEdge monitoring via the SolarEdge app.
- Check cables if using a wired connection.

If rebooting and checking connections don’t restore data transmission.
2. AC grid issues (Voltage & Frequency Errors)
Common Error Codes:
- AC Voltage Too High: 8×19 / 8x1A / 8x1B
- AC Voltage Too Low: 8x1C / 8x1D / 8x1E
- Grid Sync Error: 8x2D
What To Do:
- Check with your electricity provider – grid fluctuations can cause these errors.
- Reset the inverter by switching it off, waiting 5 minutes, and turning it back on.
- Ensure the inverter is set to the correct country. Incorrect settings can cause voltage mismatches.
When To Call A Solar Repair Service?
If voltage fluctuations persist, a licensed electrician or solar repair specialist may need to install a voltage regulator.
3. Ground fault & isolation errors (Electrical Safety Risks)
Common Error Codes:
- Ground Fault / RCD Fault: 8x2B / 8x2C / 8×39
- Isolation Fault: 8×58
- Unbalanced DC Voltage: 8×52
What To Do:
First, a very serious warning: These errors involve electrical insulation faults. DO NOT ATTEMPT DIY REPAIRS AS THEY WILL BE EXTREMELY DANGEROUS!
- Turn the inverter OFF immediately.
- Call a certified solar electrician for an inspection.
Who To Contact?

4. Overheating & temperature errors
Common Error Codes:
- Inverter Overheating: 8×47 / 8×77-79
- Faulty Temperature Sensor: 8×57
What To Do:
- Ensure the inverter is well-ventilated. Remove any objects blocking airflow.
- Check for dirt on the heat sink. If possible, clean it gently with compressed air.
- Avoid direct sunlight exposure. If possible, provide shading.
When To Call A Licensed Solar Technician?
If the temperature error persists despite adequate ventilation, internal sensors may be faulty.
5. Hardware & system failures (Major Issues!)
Common Error Codes:
- Hardware Error: 8x3E / 8×49
- Arc Fault Detected: 3×11 / 8xC
- Power Boot Error: 18×18
