SolarEdge error codes explained

Night Mode is an inverter status indicating that the input voltage is below 6 V DC.

What you can do

• This is normal at dawn, dusk, in heavy cloud or when panels are shaded
• No action needed if it clears once the sun is up
• If it shows in full sun, call your installer

Ground current surge.

What you can do

• Keep clear - do not touch the inverter, frames or cabling
• Leave the system off if it has shut down
• If you see smoke, smell burning or hear crackling, keep everyone away and call 000
• Call a licensed electrician or Total Solar to test the earthing

Ground faults may occur due to insufficient insulation to the ground.

What you can do

• Keep clear - do not touch the panels, rooftop isolators, DC cables or the inverter
• Note the code and whether it appears in wet weather or early morning - this helps the electrician
• If you see smoke, smell burning or hear crackling, keep everyone away and call 000
• Call a licensed electrician or Total Solar - insulation and earth faults need testing with proper equipment

AC voltage surge.

What you can do

• This is usually caused by the mains supply, not the solar system
• The inverter normally reconnects by itself once grid voltage is back in range

The SolarEdge system normally eliminates DC overvoltage errors.

What you can do

• Do not touch the DC isolators or cables
• Note the time - this often shows on cold, very sunny mornings
• Call your installer - the panel strings may need to be checked against the inverter's limits

Vref1V or Vref2V > +/-3%

What you can do

• Note the code, time and whether it clears by itself
• You may restart the system once using the owner shutdown/start-up steps in your manual. Do not open covers or touch cabling

Over temperature.

What you can do

• Check from a safe distance that the inverter is shaded, has clear space around it and that nothing is blocking the vents
• It usually recovers once it cools down
