SMA SB Sensor Box Summary
Product Type

SMA Sunny Sensor Box

SMA Sunny Sensor Box

The weather station for PV plants

The Sunny SensorBox is installed directly onto the modules and measures the sun radiation and temperature. In combination with Sunny WebBox and Sunny Portal, it provides a continuous target-actual comparison of plant performance. This makes it possible to detect shade, dirt, and gradually declining performance in a generator and thus maximizes yield security. Additional sensor for optional measurement of ambient temperature or wind speed permit more precise calculations.

Features of the SMA Sunny Sensor Box:


  • Rapid error detection via continuous target-actual comparison of plant performance


  • Precise acquisition of irradiation intesity, module temperature, ambient temperature and wind speed values
  • Automatic calculation of system performance ratios via Sunny Portal

Easy to install

  • Easy installation on the solar generator
  • Simple integration into existing PV plants via RS485
  • Data analysis on any PC or in the Sunny Portal
