SolarEdge, founded in 2006, is a uniquely Israeli-based global leader in smart energy solutions, providing innovative solar inverters and energy management systems. The brand entered the exponentially-growing Australian market in 2012, quickly establishing itself as one of the top choices for residential and commercial solar systems. One standout feature of SolarEdge inverters, for instance, is their unique approach to fault reporting. While many inverter brands use numeric codes to indicate faults, SolarEdge inverters tend to display descriptive error messages, making troubleshooting more intuitive for users.
Having SolarEdge inverter problems and need some help? We’re more than happy to help with our exclusive and universal guide.
These error messages, prominently visible on the inverter’s LCD – or perhaps through the SolarEdge monitoring platform – help frustrated users just like you identify and address issues quickly. In our guide, we’ll walk you through the most significant and common SolarEdge error messages, explaining their meanings, and outlining what to do when they flash before your eyes:
The SolarEdge error messages you’re most likely to see
Through our own extensive, hands-on experience working on SolarEdge systems throughout Brisbane and beyond – and hours of industry research on top of that – we’ve identified the most commonly encountered error messages. Here’s our exclusive SolarEdge solar inverter error codes guide, because all we want to do is to get your solar system working like a song again.
1. AC voltage too high (Line 1/2/3)
Meaning: The grid voltage has exceeded the acceptable limit for safe operation.
What to do:
- Check that the inverter is configured for the correct Australian country standards
- Consult your utility provider to assess grid conditions
- If allowed, adjust the grid protection settings with the help of a certified installer
- Contact SolarEdge Support Australia.
2. Ground current surge
Meaning: A surge in ground current indicates possible insulation issues in the solar array.
What to do:
- Turn off the inverter and disconnect the AC breaker
- Isolate each DC string to identify the faulty one
- Try the Solar Edge contact number: 1800 465 567
- Contact a certified private solar technician for deeper and faster inspection.
3. DC voltage too high
Meaning: The direct current voltage from the solar panels exceeds the inverter’s limits.
What to do:
- Inspect the panel strings for wiring errors or faults
- Recommission the inverter after verifying connections.
4. AC current surge
Meaning: A sudden spike in alternating current has been detected.
What to do:
- Inspect the AC connections
- Verify stability in the local grid supply.
If the issue keeps happening, contact SolarEdge support.
5. Arc fault detected
Meaning: The inverter has identified a potential arc fault in the solar system wiring.
What to do:
- Shut down the system immediately to avoid fire hazards
- Contact a certified technician to inspect and repair the wiring.
6. Temperature too high
Meaning: The inverter’s operating temperature has exceeded safe levels.
What to do:
- Ensure the inverter has adequate ventilation and is free from obstructions
- Check for debris in the heat sink and clean if necessary.
7. Isolation fault
Meaning: The photovoltaic system is not adequately isolated from the ground.
What to do:
- Inspect the PV system for potential ground leaks
- A certified installer must address and fix isolation faults before reconnecting the system.
8. Communication error
Meaning: The inverter is unable to communicate with the monitoring system or optimisers.
What to do:
- Check the network connection
- Restart the inverter and verify system communication.
If that doesn’t work, contact SolarEdge Australia tech support.
9. RCD Current Surge
Meaning: A residual current surge has been detected, potentially indicating ground faults.
What to do:
- Disconnect the system and inspect the wiring for faults
- Contact a certified technician to repair the issue.
10. No country selected
Meaning: The inverter’s country settings are not configured correctly for Australia.
What to do:
- Access the inverter’s setup menu to select the correct country code
- Follow the installation guide for the country-specific settings for Australia.
