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.

3.1 Appropriate Usage
Sunny SensorBox
The Sunny SensorBox is a device designed to provide sensor data for SMA communication products
via the RS485 Power Injector or the SMA Power Injector with Bluetooth.
The Sunny SensorBox may only be used for the purposes described in this manual. This also applies
to individual components such as the RS485 Power Injector or SMA Power Injector with Bluetooth.
The device is suitable for both private and industrial use. The Sunny SensorBox may only be used in
areas defined in the technical specifications.
Only use the original accessories of SMA Solar Technology AG or accessories recommended by
SMA Solar Technology AG.
Be sure to carefully read the entire manual before starting up the Sunny SensorBox. Store this manual
where it can be accessed at all times.
RS485 Power Injector
The RS485 Power Injector is used to integrate the Sunny SensorBox into the RS485 communication
bus. The RS485 Power Injector also supplies the Sunny SensorBox with power. A single RS485 Power
Injector can power up to five Sunny SensorBoxes.
Up to 50 bus nodes, including the Sunny SensorBox, can be added to an RS485 communication bus.
The RS485 Power Injector supports the following communication products:
•Sunny WebBox
• Sunny Boy Control/Plus with Sunny SensorBox hardware version B2 or higher
•Sunny Data Control
The RS485 Power Injector is intended for indoor installation. All electrical connections are to be
carried out by qualified personnel exclusively.
SMA Power Injector with Bluetooth
The SMA Power Injector with Bluetooth is used to integrate the Sunny SensorBox into an SMA
Bluetooth network. The Sunny SensorBox supplies measurement data and various parameters to the
SMA Power Injector with Bluetooth. The device then sends the data to the SMA communication
products over the SMA Bluetooth network. The SMA Power Injector with Bluetooth can be used to
bridge gaps in the SMA Bluetooth network, which can also be done using the SMA Bluetooth
Repeater. The SMA Power Injector with Bluetooth also s upp lie s th e Su nny SensorBo x wi th p owe r. Y ou
can only operate one Sunny SensorBox with the SMA Power Injector with Bluetooth.
However, you can add multiple SMA Power Injectors with Bluetooth to an SMA Bluetooth network
and have each one connected to a separate Sunny SensorBox. An SMA Bluetooth network can
accommodate the following number of nodes:
10 Sensorbox-IEN100914 Installation Guide
SMA Solar Technology AG Safety
• If one master* device is used, then you can connect up to 50 devices, including one or more
Sunny SensorBoxes.
• If two master devices are used, you can connect up to 25 devices, including one or more Sunny
Sensor Boxes.
The SMA Power Injector with Bluetooth supports the following communication products:
•Sunny WebBox with Bluetooth Wireless Technology
•A Bluetooth-enabled computer and the Sunny Explorer software program, version 1.1.11 or
higher
•All the SMA Bluetooth products described in the communication product's manual are
supported to ensure SMA Bluetooth wireless connectivity.
• The Sunny Beam with Bluetooth is not supported.
The SMA Power Injector with Bluetooth is intended for indoor installation. All electrical connections
are to be carried out by qualified personnel exclusively.
3.2 Safety Precautions
General Safety Precautions for Preventing Injury
• The RS485 Power Injector and SMA Power Injector with Bluetooth ma y on ly b e op era ted wit hin
their designated voltage range.
• Never open the device or the plug-in power supply unit.
• Always lay cables so that nobody can step on or trip over them.
• Work on rooftops entails a safety risk, and requires special safeguards to be implemented.
General Information for Preventing Damage to the Device
• Touching electronic components can cause an electrostatic discharge (ESD) that may damage
or even destroy the device. Unless necessary, avoid touching any connectors or plug contacts.
Ground yourself before working on the device.
• Make sure the Sunny SensorBox is integrated into the existing lightning protection system.
• When working outdoors, do not allow any water (e.g., from rain or snow) to enter the Sunny
SensorBox while it is open.
*
Master is a term used in network technology. In a network, a master is a device that prompts other devices (slaves) to perform a
specific task such as receiving or sending data. In an SMA Bluetooth network, all SMA communication products (e.g., Sunny Explorer, Sunny Beam with Bluetooth, etc.) are master devices.

6 Mounting the Device
6.1 Sunny SensorBox
6.1.1 Requirements for the Mounting Location
Mount the Sunny SensorBox either on the mounting rails of the PV mounting system or on rafters.
Observe the following information concerning the mounting location of the Sunny SensorBox:
• The Sunny SensorBox is suitable for outdoor installation.
• The ambient temperature must lie between –25 °C and +70 °C.
• If you decide to use the integrated solar radiation sensor, make sure the Sunny SensorBox is
mounted at the same tilt angle and orientation as the PV module so that the s ensor readings you
obtain can be directly compared to the yield of the PV system.
• Which mounting location to choose depends on which sensors are used. Observe the cable
lengths specified in the sensor manual.
• The maximum cable length from the final Sunny SensorBox to the RS485 Power Injector is
150 m.
• T he m axi mum cabl e le ngt h fr om th e Su nny Sen sor Box t o th e SMA Power Injector with Bluetooth
is 150 m.
• As depicted below, the Sunny SensorBox may be mounted in three different alignments to keep
water from entering and damaging the device. The Sunny SensorBox may not be mounted

Mounting the Sunny SensorBox on a Mounting Rail
You can mount the device on a module frame provided the mounting rail protrudes from beneath the
sides of the modules by approximately 16 cm.
1. The mounting location should be determined based on the amount of space available and the
prescribed orientation of the Sunny SensorBox (see page 20).

2. Attach the mounting plate onto the module rail with
the screws and slot nuts provided by the
manufacturer of the PV mounting system.
Usually any screw up to M10 in size fits into the slot
nuts.
3. Op en the si de f laps of t he S unn y Sensor Box usi ng the

sensor:
• Select a PV module that remains unshaded throughout the day.
• Do not attempt to extend or shorten the pre-assembled 2.5 m cable.
• The module temperature sensor is affixed to the back of the PV module.
Included Mounting Accessories
Position Quantity Designation
A 1 PT100 module temperature sensor with 2.5 meter connection cable
B1 Thermally conductive adhesive (protective gloves, hardener and binder) with
instructions and packaging
C2 Adhesive strips
Mounting the Temperature Sensor on the PV Module
CAUTION!
Risk of chemical burns from contact with the thermally conductive adhesive.
• Avoid any contact with the skin, mucous membranes and eyes.
• Wear appropriate protective clothing, gloves and goggles when working on the
sensor.
• Follow the safety precautions and instructions from the manufacturer of the thermally
conductive adhesive.
1. The mounting location should be determined based on the cable length of the sensor and the
applicable site requirements.
