6.4 SMA Power Injector with Bluetooth
6.4.1 Requirements for the Mounting Location
Observe the following requirements regarding the mounting location of the SMA Power Injector with
Bluetooth:
• The SMA Power Injector with Bluetooth is intended for indoor installation only.
• The mounting location must be in the vicinity of a 100 V … 240 V socket (plug-in power supply
cable length approx. 180 cm).
• Protect the SMA Power Injector with Bluetooth from dust, moisture and corrosive substances.
• The ambient temperature must remain between –20 °C and +65 °C.
• The maximum cable length from the Sunny SensorBox to the SMA Power Injector with Bluetooth
is 150 m.
• The maximum cable length for the alternate power supply device is 10 m.
• The wireless link at the mounting location should have a connection quality rating of "good" or
higher (see section 6.4.3 ”Determining the Mounting/Installation Location” (page 31).
• Certain ambient conditions can reduce the connection quality and data transmission speed
between Bluetooth devices.
– Mount or install the Bluetooth device at a distance of at least 1 m from the following devices:
– WLAN devices
– Microwave ovens
– Other devices that use the 2.4 GHz frequency band
6.4.2 Information on SMA Bluetooth
The SMA Bluetooth devices of your PV system can communicate and network with an SMA Bluetooth
communication product via Bluetooth wireless technology. To ensure the devices communicate with
each other and are interlinked, they have to be set to the same NetID. The NetID is the unique
identification number of your PV system. It can therefore be used to distinguish your PV system from
other SMA Bluetooth PV systems.
Determining the NetID for your PV System
If your Bluetooth PV system does not have a NetID yet, you first need to determine a free
NetID with the Sunny Explorer or Sunny Beam with Bluetooth software applications and
then set the devices of your PV system accordingly.
