5 Preparing for Mounting and Commissioning of the

Sunny Home Manager

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.

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.

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.

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.
