2 Safety
2.1 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 must 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 must only be used in
areas defined in the technical specifications.
Only use the original accessories of SMA or accessories recommended by SMA.
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 supplies the Sunny SensorBox with power. You
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:

SMA America, LLC Safety
Installation Manual Sensorbox-eng-IA-IUS-112515 13
• 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 manuals for communication products 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
must be carried out by qualified personnel.
*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 Ex-
plorer, Sunny Beam with Bluetooth, etc.) are master devices.

2.2 Safety precautions
DANGER
High voltages are present in the Sunny Boy during operation.
Death or serious injury due to electric shock.
• All work on the Sunny Boy must only be carried out by qualified personnel.
DANGER
Falling from high altitude when mounting and installing the Sunny SensorBox.
Death or serious injury will result.
• All work on rooftops must only be carried out by qualified personnel.
CAUTION
Overvoltage in case of lightning strike.
Fire and damage to connected devices will result.
• Integrate the Sunny SensorBox into the lightning protection system, if existing.
NOTICE
Electrostatic discharges.
Internal components of the device can be damaged irreparably by electrostatic discharge.
• Ground yourself before working on the device.
• Avoid touching any connectors or plug contacts.
NOTICE
Ingress of water into the open Sunny SensorBox.
Damage to the Sunny SensorBox will result.
• Before working on the device unplug the plug-in power supply unit.
• When working outdoors, avoid water, rain or snow to enter the Sunny SensorBox.

Installation Manual Sensorbox-eng-IA-IUS-112515 15
3 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.
You can compare radiation levels and PV power based on the radiation intensity (W/m2) 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.
