LED Signals
The LEDs indicate the operating state of the inverter.
LED signal | Explanation |
|---|---|
Green LED and red LED flash simultaneously (2 s on and 2 s off) | No country data set set Operation of the inverter is stopped because no country data set is set. The inverter automatically starts operation as soon as the configuration has been carried out (e.g., using the commissioning wizard or via a System Manager). |
The green LED is flashing (2 s on and 2 s off) | Waiting for feed-in conditions The conditions for feed-in operation are not yet met. As soon as the conditions are met, the inverter will start feed-in operation. |
The green LED is flashing (1.5 s on and 0.5 s off) | Battery-backup operation The battery-backup operation is activated and the inverter supplies the loads with energy from the battery. |
The green LED is glowing | Operation The inverter is in operation. |
The green LED is off | No voltage is applied to the PV system or battery. |
The red LED is glowing | Error Inverter operation has been stopped. In addition, a distinct event message and the corresponding event number will be displayed on the product user interface or in Sunny Portal. |
Red LED is flashing (0.25 s on, 0.25 s off, 0.25 s on, 1.25 s off) | Warning Communication with a superordinate plant controller has failed. The inverter continues to operate with restricted function (e.g. with set fallback level). In addition, a distinct event message and the corresponding event number will be displayed on the product user interface or in the communication product (e.g. Sunny Home Manager). |
The blue LED is flashing slowly (2 s on and 2 s off) | Communication connection is being established. The inverter is establishing a connection with a local network or is establishing a direct connection to a smart device (e.g., smartphone, tablet, or laptop). |
The blue LED is flashing fast (0.25 s on and 0.25 s off) | A communication product requests identification of the inverter. |
The blue LED is glowing | There is an active connection with a local network (LAN/Wi-Fi) or there is a direct connection (Ethernet/WPS function) with a smart end device (e.g., smartphone, tablet or laptop). |
Blue LED is off | There is no active connection. |
All 3 LEDs are on | Inverter update or booting procedure. |
