SolarEdge Solar Inverters & Power Optimisers Error messages
SolarEdge inverters come standard with 12 year warranties, this is far longer than a standard solar inverter warranty of 5 years.
SolarEdge power optimisers come standard with a 25 year warranty, that is the same length as the performance warranty on the solar panels they are connected too.
The Limited warranty for SolarEdge solar power inverters and the solar panel optimisers does not cover labour costs of a third party to travel to your property and replace or repair the units, however Gold Coast Solar Power Solutions are a SolarEdge Certified Installer and as a certified installer SolarEdge will cover our labour costs for any warranty work.

SW Error | Contact SolarEdge Support |
| 9, 13 | 2×9, 2xD | AC Current Surge Vac surge |
Ground current surge. 1. Check the AC connection to the inverter 2. Check with the grid operator if a large surge source or irregular load exists near the site. 3. If the grid does not have problems contact SolarEdge support. |
| 10, 37, 38 | 2xA, 2×25, 2×26 |
Ground Current – RCD |
Ground faults may occur due to insufficient insulation to the ground.
Only a qualified technician should handle this problem, and only after taking proper precautions. |
| 14 | 2xE | AC Voltage Too High (Line 1/2/3) |
AC voltage surge. If the fault persists: 1. Check the AC connection to inverter. 2. Verify that the inverter is set to the correct country. 3. Check with the grid operator if a large surge source or irregular load exists near the site. 4. Verify that the output wire size matches the distance between the inverter and the location of the grid connection. 5. Use a larger gauge wire for the AC output. 6. Refer to the AC Wiring Application Note |
