How to power cycle (reset) your SolarEdge inverter
If you have a SolarEdge HD Wave or A-US Inverter displaying error codes or a SetApp inverter displaying a red fault light, then power cycling is a good next step. There are some error codes (Ground Faults and Isolation Errors) where it does not make sense for safety reasons. In those cases, contact SunCommon Customer Support.
Here is how you power cycle a SolarEdge inverter:
1) Flip the red switch into the off position, this is located either above the black dial/DC disconnect or on the left side in the back of your inverter.
2) Wait five minutes or until the DC voltage reading on your inverter goes below 50 VDC, if you have a screen.
3) Turn off the DC disconnect, this is the black dial right on the front of the inverter. Simply turn it to the “off” position.
4) Turn off your system’s AC disconnect. This is located outside next to your utility meter. Look for a grey box with a lever that you’ll pull down into the “off” position. If you do not see this, that means your AC disconnect is a breaker underneath your Net Meter, or ConnectDER, that you will need to flip off. You’ll need to unscrew the grey cover to access the breaker. See below for reference photos.
5) Wait 30 seconds and then turn them back on in reverse order. Throw the AC lever back up into the “on” position, turn the dial on the inverter back to the “on” position, and flip the red switch.
The inverter will start to turn back on and may take a few minutes to reboot. You should see the main screen as normal or the red fault light clear once the reboot is complete with no error message. If the issue persists, please contact SunCommon Customer Support.
