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 sensor 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.
• The maximum cable length from the Sunny SensorBox to the 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
vertically with the SMA logo on the top, as this would allow water to penetrate into the device
through the ventilation membrane.
