☑ The start-up phase begins.
☑ The green LED is glowing and the display alternates between the firmware version, the serial
number or designation of the inverter, the NetID, the IP address, the subnet mask, the
configured country data set and the display language.
✖ The green LED is flashing?
Possible cause of error: the DC input voltage is still too low or the inverter is monitoring the
utility grid.
• Once the DC input voltage is sufficiently high and the grid connection conditions are met,
the inverter will start operation.
✖ The red LED is glowing and an error message and event number appear in the display?
• Rectify the error (for troubleshooting see service manual at www.SMA-Solar.com).
