How to power cycle (reset) your SMA Sunny Boy inverter

If you have an SMA inverter displaying error codes then power cycling (or restarting) is a good next step. If you have a Ground Faults or Isolation Errors, do not attempt to power cycle your device because of electrical hazards. Contact SunCommon Customer Support.

Here is how you power cycle a SMA Sunny Boy inverter:

1) Turn off the DC disconnect. This is the black dial on the underside of your inverter. Simply turn it to the “off” position.

2) Turn off your system’s AC disconnect. This is located outside next to your utility meter and is just a lever that you’ll pull down into the “off” position.

3) Wait 5 minutes and then turn them back on in reverse order. Throw the AC lever back up into the “on” position and turn the dial on the inverter back to the “on” position.

If you’re resetting an “Arc Detected” code, watch the inverter screen after reenergizing it. You should see a prompt to knock on the inverter to clear the code officially.

After these steps, the inverter will start to turn back on and may take a minute or two to reboot. You should see the main screen as normal once the reboot is complete with no error message. If the issue persists, please contact SunCommon Customer Support..
