Product catalog summary
Overview
The 3S-IS Irradiance Sensor is part of the SEVEN meteorological sensor series, designed for environmental and industrial applications, particularly photovoltaic (PV) installations. It provides irradiance data in W/m² to calculate the performance ratio of PV plants. The sensor is available with various outputs to meet customer requirements and transmits data to data loggers and receiving units.
Specifications and Standards
The sensor is designed to meet standards such as IEC 61724 and IEC 60904. It uses high-quality components for accurate data and includes temperature compensation for irradiance readings. The sensor is compliant with Class A standards, ensuring high accuracy and reliability.
Models and Features
Several models are available, including:
  • 3S-IS-T-1,5V: 0–1.5 V analog output
  • 3S-IS-T-10V: 0–10 V analog output
  • 3S-IS-LR: Low-cost model for residential and small-scale PV systems
All models measure irradiance and cell temperature, with temperature-compensated readings. The sensors connect to data loggers via appropriate analog inputs or RS-485 bus using the Modbus RTU protocol.
Technical Specifications
The sensors have a silicon reference cell and measure various meteorological data, including irradiance, temperature, wind speed, and humidity. Key specifications include:
  • Irradiance Range: 0 - 1600 W/m²
  • Uncertainty: ≤ 1% (Class A)
  • Resolution: 0.1 W/m²
  • Response Time: 1 second
  • Operating Temperature: -40°C to +85°C
  • IP Rating: IP54 (optional IP68)
Each sensor is calibrated under a Class AAA Sun Simulator according to IEC standards.
Installation and Connectivity
The sensors are fast and simple to install, with a structure similar to PV panels. They support free software updates and are SunSpec compliant for Modbus RTU. SEVEN offers remote setup service and customer support, with a 5-year warranty.

Irradiance Sensor (3S-IS)-1

Irradiance Sensor The Irradiance Sensor is part of the SEVEN meteorological sensor series which includes professional and intelligent measurement sensors with a digital or analog interface for environmental and industrial applications such as photovoltaic installations. The Irradiance Sensor, also known as PV Pyranometer with photovoltaic reference cell, provides users with irradiance data in W/m² for calculating the performance ratio of PV plants. Irradiance Sensors are available with various outputs to meet customer requirements. Measured irradiance data is transmitted to data loggers and receiving units according to the input requirements. SEVEN products use reliable, high-quality components to deliver accurate meteorological data for environmental and industrial applications. The Irradiance Sensor is specifically designed to meet the requirements of PV plant monitoring systems, based on standards such as IEC 61724 and IEC 60904. All irradiance sensors except the Low-Cost Irradiance Sensor use the cell temperature value to produce a temperature-compensated irradiance reading. Benefits and Features • Class A Compliance • Fast & Simple to Install • Similar Structure with PV Panels • Free Software Updates • SunSpec Compliant (for Modbus RTU) • SEVEN Remote Setup Service • SEVEN Customer Support • 5 Year Warranty Models 3S-IS The 3S-IS Modbus Irradiance Sensor is designed for professional use in industrial, commercial, and utility-scale photovoltaic installations. The Irradiance Sensor functions as a main hub to which ambient & module temperature, wind speed & direction, and relative humidity sensors can be connected. All measured meteorological data is transmitted to data loggers and receiving units via a 3-wire RS-485 bus using the Modbus RTU protocol. 3S-IS-T-I The 4-20 mA analog output irradiance sensor measures irradiance and cell temperature. The measured irradiance value is temperature-compensated. The 4-20 mA Irradiance Sensor connects to the appropriate analog inputs of data loggers or other receiving units. 3S-IS-T-1,5V The 0–1,5 V analog output irradiance sensor measures irradiance and cell temperature. The measured irradiance value is temperature-compensated. The 0–1,5 V Irradiance Sensor connects to the appropriate analog inputs of data loggers or other receiving units. 3S-IS-T-10V The 0–10 V analog output irradiance sensor measures irradiance and cell temperature. The measured irradiance value is temperature-compensated. The 0–10 V Irradiance Sensor connects to the appropriate analog inputs of data loggers or other receiving units. 1 Pınarçay OSB Mahallesi 11.

Irradiance Sensor (3S-IS)-2

Irradiance Sensor The Low-Cost Irradiance Sensor is designed specifically for residential and rooftop applications, or small-scale PV systems. For these applications, the advanced features and high accuracy of professional meteorological sensors are not required. The cost of the sensor should be proportional to the scale of the PV system and with the Low-Cost Irradiance Sensor, SEVEN achieves exactly that. The measured irradiance value is transmitted to data loggers and receiving units via a 2-wire RS-485 bus using the Modbus RTU protocol. External module temperature, ambient temperature, and...
