5 Preparing for Mounting and Commissioning of the
Sunny Home Manager
5.1 Preparing for BLUETOOTH Communication
If the Sunny Home Manager is to communicate with other SMA devices via BLUETOOTH,
e.g. with SMA radio-controlled sockets, you must carry out the following preparatory steps.
5.1.1 Commissioning a BLUETOOTH PV System
All devices must be set to the same NetID so that the SMA BLUETOOTH devices in a PV system can
communicate with each other. The NetID is used to distinguish between PV systems using
SMA BLUETOOTH located in close proximity to one another.
The NetID can be a number from 1 to 9 or a letter from A to F.
To make sure that you do not set a NetID which is already being used by another BLUETOOTH PV
system in the vicinity, you need to determine a free NetID prior to commissioning your BLUETOOTH
PV system.
Procedure
1. If another system with BLUETOOTH is located within 500 m of your system, determine a free
NetID at the planned mounting location of every BLUETOOTH device and make a note of this
(see Sunny Explorer manual).
2. For all devices that are to communicate with the Sunny Home Manager via BLUETOOTH,
set the previously noted free NetID and commission the devices (see manual of BLUETOOTH
device or BLUETOOTH Piggy-Back).
3. Note the serial numbers of the Sunny Home Manager and all other SMA devices. For the
SMA radio-controlled sockets, also note the load that you wish to assign to the respective
SMA radio-controlled socket.
Requirement for detecting a free NetID
You can only detect a free NetID using a computer with integrated BLUETOOTH or with a
BLUETOOTH stick (BLUETOOTH class 1) and the software Sunny Explorer (see Sunny Explorer
help). You can obtain Sunny Explorer free of charge from the download area at
www.SMA-Solar.com.
Requirement for selecting NetID "1" as the NetID of the PV system
For BLUETOOTH devices, NetID 1 is preset at the factory. If NetID 1 is set in the Sunny Home
Manager, it can connect to a maximum of one other device via BLUETOOTH or Speedwire.
• If you would like to connect more SMA devices than one inverter and
one Sunny Home Manager, select a NetID other than NetID 1.
