General status LED (red): This will be where most errors can be monitored. This LED will activate if: 

  • A status message is being displayed on the monitor.
  • The process of feeding energy into the grid is interrupted.
  • The inverter is waiting for an error to be rectified.

Startup LED (orange): The main light when the system isn’t handling energy. This LED will activate if: 

  • The inverter is in its automatic startup or self-test phase (as soon after sunrise as the solar modules are delivering sufficient power).
  • The inverter has been switched to Standby mode in the Setup menu (= feeding energy into the grid switched off manually).
  • The inverter software is being updated.

Operating status LED (green): This LED should be on during majority of the day. It will activate if: 

  • The PV system is working correctly after the inverter's automatic startup phase.
  • All the time while energy is being fed into the grid.
