The green LED indicates whether power is being produced, i.e., the unit is operating. A green LED that is constantly on indicates that power is being generated. If the green LED is off, no power is being produced, such as at night. If the green LED is off while there is enough sun on the panels, there may be a malfunction: Please contact us. If you have reset the inverter, the green LED will first blink for a while during the start-up phase. 

A steady blue LED indicates that communication is taking place with the monitoring platform. If the blue LED is flashing, it usually means that the device is still establishing the connection with the monitoring platform (via the internet)

The red LED indicates that a malfunction has occurred. A red LED that stays on is a signal to contact our service department. A red LED flashing occurs when the inverter is turned off.
