3S-IS-1/2/3 - CẢM BIẾN BỨC XẠ CLASS A ​​​​​​​3S-IS-1/2/3 SEVEN VIỆT NAM - IRRADIANCE SENSOR CLASS A 3S-IS-1/2/3

3S-IS is  an advanced CLASS A solar irradiance sensor developed by SEVENSENSOR , specifically used in solar PV systems.
The device helps to accurately measure solar radiation intensity and photovoltaic cell temperature, providing important input data for monitoring, performance evaluation and system maintenance.

The sensor is designed with Modbus RTU (RS-485) communication , easy to integrate into SCADA systems, PLC or industrial dataloggers. Each device is factory calibrated to international standards, ensuring accuracy and long-term reliability.

2. 3S-IS product lines

The 3S-IS product line includes many different models, meeting a variety of monitoring needs from basic to advanced:

3. Practical application

3S-IS series radiation sensors are applied in many fields:

• Solar Power System Performance Monitoring (PV Performance Monitoring)
  Measure actual radiation intensity at the installation point to calculate performance ratio and detect operational deviations.

• SCADA / Datalogger / PLC system Modbus RTU
  communication makes it easy to connect and transmit real-time data to the central control and monitoring system.

• Environmental and climate analysis at PV stations
  Extended models can measure additional wind speed, ambient temperature, humidity, etc. to study the impact of weather on energy efficiency.

• The 3S-IS-LR
  version of the Rooftop Solar System is low cost, easy to deploy, and still ensures the accuracy needed for a small residential or commercial project.

• Solar Research and Testing
  Used in laboratories and testing centers to collect irradiance data, analyze environmental conditions and optimize PV systems.

4. Outstanding technical advantages of 3S-IS

• Complies with international standard IEC 61724-1 Class A , ensuring high accuracy.

• Measurement error ≤ 1% , long-term stability, low drift coefficient (< 0.3%/year).

• 1 Hz sampling rate , fast response, suitable for continuous monitoring.

• Factory calibration with Class AAA equipment ensures data reliability.
