5.2 Determining the Mounting / Installation Location for Bluetooth
PV Plants
5.2.1 Information on SMA Bluetooth
The devices in your PV system can communicate and network with a communication device via
Bluetooth. To ensure the devices communicate with each other and are interlinked, they have to be
set to the same NetID. The NetID is a unique identification number of your PV plant. Thus, the NetID
distinguishes your PV plant from other PV plants.
5.2.2 Determining the Mounting / Installation Location
Before you mount the Sunny WebBox, you should determine the connection quality at the mounting
/ installation location of the Sunny WebBox to your PV plant. The connection quality can be checked
using the Sunny Explorer or the Sunny Beam with Bluetooth. Refer to the user manual of the relevant
device. You can change the connection quality by changing the distance between the Bluetooth
devices.
5.2.3 Extension of the Bluetooth Network Using an SMA Bluetooth
Repeater
The SMA Bluetooth Repeater can help you extend the wireless range of your Bluetooth network. An
SMA Bluetooth Repeater installed on the range border of the Bluetooth network transmits the data
traffic of this network in its own radio range. This technology enables the construction of Bluetooth
networks which cover a much larger area than would be possible using the Sunny WebBox alone.
Determining a NetID for your PV plant.
If your PV plant does not have a NetID yet, you must first determine a free NetID using the
Sunny Explorer software or using the Sunny Beam with Bluetooth and then set this in the
devices of your PV plant.
NetID 1 is currently not supported by the Sunny WebBox with Bluetooth.
A direct connection to an individual SMA Bluetooth device via NetID 1 is currently only
possible with the Sunny Explorer software or the Sunny Beam with Bluetooth.
Change the NetID of the Sunny WebBox with Bluetooth to the NetID of your PV plant
(NetID 2 to NetID F).
