Fronius Datcom Irradiance Sensor - 4,30,00,11,189
The Fronius Datcom Irradiance Sensor, identified by the part number 4,30,00,11,189, is specifically designed for measuring the irradiated energy of solar modules. This essential device assists in assessing the performance of your photovoltaic (PV) system by providing a rapid overview when comparing irradiated power to inverter outputs. This ensures optimal operation and enhances energy efficiency, making it a valuable addition to any solar setup.
Featuring a mono crystalline Si-Sensor, the Fronius irradiance sensor produces approximately 70mV at 1000W/m², ensuring accurate readings that help users monitor their solar energy production effectively.
This sensor maintains its functionality across a broad temperature range, operating efficiently between -40°C to +85°C. This makes it suitable for various environmental conditions, ensuring reliable performance regardless of the weather.
The Fronius sensor is designed on a Z-shaped aluminum profile, measuring 110mm x 40mm x 40mm. Its robust construction ensures durability and ease of installation on solar module frames without obstructing light.
With the sensor pre-fixed on an aluminum profile equipped with an 8mm hole, the installation process is straightforward. Users can securely screw the sensor onto the module frame, ensuring it does not cast any shadow on the panel.
The sensor comes with a 3-meter UV-resistant copper cable, allowing for sufficient distance from the solar modules while maintaining signal integrity over a maximum length of 30 meters, facilitating convenient installation.
The Fronius Datcom irradiance sensor operates by capturing sunlight exposure that hits the solar module surface. It converts this irradiated energy into a measurable voltage output, providing real-time data on the energy produced.
The precise sensor measures irradiance values, enabling direct comparisons with inverter performance. This functionality ensures users can quickly assess if their PV system is operating at optimal efficiency.
The sensor transmits its readings through the associated cable, allowing for easy integration with the data logger. This feature supports users in monitoring performance remotely, enhancing system management capabilities.
Designed with accuracy in mind, this sensor maintains an accuracy of ±5% over the course of a year, providing dependable long-term performance and insights into solar efficiency.
