SMA Solar Technology AG The Sunny SensorBox
2 The Sunny SensorBox
With the Sunny SensorBox and the external sensors, you can collect environmental data from your
PV system which is then used for performance monitoring.
To this end, the Sunny SensorBox comes with an integrated solar radiation sensor and an external
module temperature sensor. You also have the option of connecting an ambient temperature sensor
and an anemometer to the Sunny SensorBox.
2
You can compare radiation levels and PV power based on the radiation intensity (W/m
) measured
by the integrated solar radiation sensor and the total amount of recorded power the PV system
generates in a single day. If this data is observed over a longer period, then this solution offers a
practical method of identifying any errors in your PV system. Sunny Portal (www.sunnyportal.com) or
Flashview can be used to visualize the data collected by the Sunny SensorBox.

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.
30 Sensorbox-IEN100914 Installation Guide
SMA Solar Technology AG Mounting the Device
Extending the Bluetooth Network with the SMA Bluetooth Repeater
The SMA Bluetooth Repeater can help you extend the wireless range of your Bluetooth network.
When an SMA Bluetooth Repeater is set up at the coverage boundary of a Bluetooth network, it is
capable of routing the data traffic in that network into its own wireless range. This technology allows
you to set up Bluetooth networks that cover a much larger area than would be possible with just the
Sunny SensorBox or SMA Power Injector with Bluetooth.
Further information about SMA Bluetooth Wireless Technology can be found in the download section
at www.SMA.de/en.
6.4.3 Determining the Mounting/Installation Location
Before mounting the SMA Power Injector with Bluetooth, you should first test the wireless connection
between the device and your PV system at the specified mounting/installation location. The Sunny
SensorBox does not have to be connected to the SMA Power Injector with Bluetooth in order to
perform this test.
To do so, proceed as follows:
1. Turn the "MODE" rotary switch of the
SMA Power Injector with Bluetooth to position "3".
The sole purpose of this position is to determine the
location of installation.
"MODE" ID Meaning
0 normal operation
1 for servicing purposes
only
2 for servicing purposes
only
3 installation mode
2. Turn the "NetID" rotary switch of the SMA Power
Injector with Bluetooth to the NetID of your PV
system. If your PV system does not have a NetID
yet, see section 6.4.2”Information on SMA
Bluetooth” (page30).

☑ The SMA Power Injector with Bluetooth shows the connection quality to the next available
SMA Bluetooth device. You can change the connection quality by moving the Bluetooth
devices further apart or shifting their orientation. The connection quality must be rated as
"good" or higher for the selected mounting/installation location (at least two yellow
Bluetooth LEDs glow).
– You must improve any connection that proves to be unreliable or too slow (see section
5.3.2”LEDs Indicating Connection Quality (Bluetooth LEDs)” (page18)).
4. Disconnect the power and turn the rotary switch to "MODE 0".
☑ The mounting/installation location for the SMA Power Injector with Bluetooth has now been
determined.
