skyCONNi 
Universal
Weather Unit

Our universal system for the measurement of ambient conditions. skyCONNi-Sun is capable of integrating a number of different weather sensors into the plant communication network. The basic system offers integrated ambient and module temperature sensors as well as two interfaces for the connection of irradiation sensors, be it pyranometers or reference cells. A compact weather station providing information about wind, precipitation and humidity conditions can also be connected. The skyCONNi-Sun cabinet is of robust design and suitable for outdoor installation.

Comprehensive Functions


Telescopic mast for mounting skyCONNi and sensors is available as an option.

The sensor kit is capable of measuring a wide range of weather data relevant for the operation and revenue of your PV power plant:

  • irradiation
  • ambient temperature
  • module temperature
  • atmospheric pressure and air humidity
  • wind speed
  • wind direction
  • amount, duration and intensity of rain and hail

Suitable for indoor and outdoor application:

  • wall mounting
  • module-frame mounting or
  • pole mounting

Features

  • Pyranometer air conditioning with ventilation unit for enhanced accuracy and reliability of the pyranometer
  • Reference Module Adapter (RMA) enables solar irradiation measurement in connection with thin film modules (Article No. 3RMA00151)
  • Zone Monitoring – skyCONNi-Zone: PV strings bundled to zones are measured and evaluated as a total, at the inverters’ inputs employing current transducers (not included)
