This section describes the installation of the Sunny SensorBox, the RS485-Power Injector and the
module temperature sensors.
4.1 Selecting the Mounting Location
4.1.1 Sunny SensorBox
Requirements for installation location of the Sunny SensorBox:
• The Sunny SensorBox is suitable for outdoor installation.
• The ambient temperature must be between -13 °F and + 158 °F.
• If the integrated irradiation sensor is used, the Sunny SensorBox must be installed at the same
tilt angle and with the same orientation as the PV system in order to have measuring results that
can be related to the system's yield.
• The installation location is to be selected according to the sensors used, taking into account the
sensors' maximum cable lengths.
• Module temperature sensor: prefabricated cable length 8.2 ft. The cable may not be extended
or cut.
• Ambient temperature sensor: maximum cable length 98 ft.
• Anemometer: prefabricated cable length 10 ft. (the cable may not be cut or only extended to
a maximum of 98 ft.).
• The maximum cable length from the final Sunny SensorBox to the RS485-Power Injector is
492 ft.
• The maximum cable length of the entire RS485 communication bus is 4,000 ft.
4.1.2 RS485-Power Injector
Installation location requirements for the RS485-Power Injector:
• The RS485-Power Injector is only suitable for indoor installation.
• In the vicinity of a 120 V socket (cable length of the power supply approx. 70 in.).
• Protect the RS485-Power Injector from dust, moisture and corrosive substances.
• The ambient temperature must be between -4 °F and +149 °F.
• The maximum cable length from the final Sunny SensorBox to the RS485-Power Injector is
492 ft.
• The maximum cable length of the RS485 communication bus is 4,000 ft.
