Fronius Irradiation Sensor Measures Your Real Sunlight
The Fronius Irradiation Sensor uses a monocrystalline silicon cell to measure how much sunlight reaches your array. It connects to the irradiation channel on the Fronius Sensor Box, so your monitoring can show sunlight next to production.
It is the clearest way to judge whether your system is really performing.
Why You'll Love The Fronius Irradiation Sensor
Production with context. Seeing irradiance beside output tells you at a glance whether a low day was clouds or a fault.
Calibrated cell. The calibration value is printed on each sensor, and output is about 70 mV at 1000 W/m².
Built for outdoors. Weatherproof design on a Z-shaped aluminum profile, rated -40 to +85°C.
Long cable runs. Comes with a 3 m UV-resistant cable and supports up to 30 m of cable to the Sensor Box.
Your life, with the Fronius Irradiation Sensor
You stop wondering if the panels are dirty or just having a grey week. One look at the sunlight reading next to your production graph answers it. You clean, service or relax with confidence.
