The installed SMA Bluetooth® Repeater does not increase the range.

The blue LED on the SMA Bluetooth® Repeater shows you whether it has established a connection to the Bluetooth network. The three orange LEDs show the quality of an existing connection. If you do not see at least the blue LED, then the Repeater is not integrated into the Bluetooth network. Only a master, such as the Sunny Beam with Bluetooth, can set up a Bluetooth network.

Note that an SMA Bluetooth® Repeater can only connect to other devices and thus bridge wireless gaps if the same NetID is set on the Repeater itself as on the inverters.

Check to see if the same NetID is set on all SMA inverters and SMA Bluetooth® Repeaters (NetID 2 or higher).

If you are not sure if the arrow from the NetID rotary switch on the SMA Bluetooth® Repeater is pointing to the right NetID, turn the switch back to NetID 0 and then count the clicks as you turn it back up.

It could also be, however, that the Repeater is too far away from the other devices involved and thus out of range. The Repeater can only establish a connection if the connection quality is at least good.

Move the Repeater closer to the other devices or use an additional Repeater.

Check the supply voltage of the SMA Bluetooth® Repeater, as well. If the green "RDY" LED is off or flashing, the supply voltage is either absent or too low.
