LED Signals
The LEDs indicate the operating state of the product.
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 product is stopped because no country data set is set. Once the configuration has been completed (for instance using the installation assistant or via a communication product), the product will start operation automatically. |
The green LED is flashing (two seconds on and two seconds 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 function is activated and the inverter supplies the loads with energy from the battery. |
The green LED is glowing | Feed-in operation The inverter is feeding in. |
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 higher-level 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 flashes slowly for approx. 1 minute | Communication connection is being established The product is establishing a connection to a local network or is establishing a direct connection to a smart device via Ethernet (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 |
