Determine a free NetID before installation of the SMA
Bluetooth Piggy-Back
SMA Solar Technology recommends the determination of a free NetID using a mobile
communications device (e.g. Sunny Beam with Bluetooth or a laptop with Bluetooth and the Sunny
Explorer software) before installation of the communication interface. To find out how to determine a
free NetID please refer to the relevant instructions of the communications product.
Information for the installation of the communication
interface
Take note of the following additions to the installation of the communication interface:
• The removal of the resistors from inverters of the type SWR is not necessary.
• During installation of the communication interface,
ensure that the communication interface is left-
aligned on the interface socket. The far right pins on
the lower short row of pins remain free.
Commissioning of a Bluetooth PV system always with 1 master only.
Always carry out the commissioning of a Bluetooth PV system with only 1 master (e.g.
Sunny Beam with Bluetooth, Sunny Explorer). You may integrate further masters into the
Bluetooth Network as soon as the Bluetooth network exists.
Sunny Beam with Bluetooth and SMA Bluetooth Repeater
The Sunny Beam with Bluetooth and the SMA Bluetooth Repeater can not register any
Bluetooth devices which are set to NetID 1. Only NetIDs from 2 to 9 and from A to F are
possible.
