With the Sunny SensorBox and the external sensors you can acquire environmental data at your PV
system which is relevant to performance monitoring.
For this purpose, the Sunny SensorBox has an integrated irradiation sensor as well as an external
module temperature sensor. In addition, you also have the option of connecting an ambient
temperature sensor and/or an anemometer to the Sunny SensorBox.
The Sunny SensorBox is integrated into an RS485 communication bus. A maximum of 50 bus
subscribers (incl. Sunny SensorBox) are allowed on the RS485 bus
The RS485-Power Injector provides the Sunny SensorBox with power, and must be mounted indoors.
Up to 5 Sunny SensorBox devices can be connected to an RS485-Power Injector.
