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. Once the configuration has been completed (for instance using the installation assistant or via a communication product), the inverter will start operation automatically. |
The green LED is flashing (2 s on and 2 s off) | Waiting for valid operating conditions The conditions for charging and discharge mode are not yet met. As soon as the conditions are met, the inverter will start charging and discharging. |
The green LED is glowing | Charging and discharge mode The inverter charges or discharges the battery in current-controlled operation (e.g. on the utility grid). |
The green LED is off | No battery voltage |
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 inverter user interface or in the communication product (e.g. SMA Data Manager). |
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 inverter user interface or in the communication product (e.g. SMA Data Manager). |
The blue LED is flashing slowly (2 seconds on and 2 seconds off) | Communication connection is being established. The inverter is establishing a connection to a local network (Ethernet/Wi-Fi) or is establishing a direct connection (Ethernet/Wi-Fi) to an end device (e.g. computer, tablet PC or smartphone). |
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 (Ethernet/Wi-Fi) or there is a direct connection (Ethernet/Wi-Fi) with an end device (e.g. computer, tablet PC or smartphone). |
Blue LED is off | There is no active connection. |
All 3 LEDs are on | Inverter update or booting procedure |
