The JW-F04 portable irradiance meter adopts industry-leading optical sensing technology, with measurement accuracy and stability reaching the advanced level in China. The equipment is equipped with a secondary standard spectral response sensor and a multi-channel optical detection module, with a spectral response range covering 300-1100nm, perfectly matching the spectral response characteristics of photovoltaic modules, ensuring that the measured data highly matches the actual received light energy of the modules. It can synchronously and accurately measure the total solar irradiance, scattered radiation, reflected radiation, and effective irradiance of photovoltaic module planes. The measurement range is 0-2000W/㎡, with a resolution of 1W/㎡ and a measurement error of less than ± 2%. The data is stable and not affected by changes in temperature, humidity, and lighting angle. The sensor adopts high transparency dust-proof protective lenses with self-cleaning function, which can reduce the impact of dust and water vapor adhesion on measurement accuracy. Long term outdoor use does not require frequent calibration, reducing maintenance costs.
Portable and lightweight design, suitable for complex outdoor scenes, achieving flexible and efficient monitoring. The JW-F04 machine is designed with a lightweight structure, weighing only 3kg and having a compact size. Paired with a dedicated portable backpack, it can be easily carried by a single person to any monitoring point. The equipment is equipped with a lightweight bracket with adjustable height, which is easy to install without the need for professional tools. It can be installed and debugged in just one minute and is suitable for various photovoltaic power plant scenarios such as roofs, mountains, deserts, and water surfaces. The protection level of the whole machine reaches IP65, and the waterproof and dust-proof housing can withstand rainstorm, sand dust, high temperature, cold and other harsh environments. The operating temperature range is -40 ℃ to+60 ℃, and the humidity is 0-95% RH, which is non condensing, meeting the long-term continuous outdoor monitoring needs. Built in large capacity long-lasting lithium battery, with a battery life of up to 12 hours, supports uninterrupted monitoring throughout the day, and can also be connected to solar charging panels to achieve self-sufficient outdoor power supply, ensuring monitoring continuity.
Intelligent data management and multifunctional design improve monitoring efficiency and simplify data analysis processes. JW-F04 is equipped with a high-precision data acquisition and storage module, which can collect real-time irradiance data and support recording at multiple time intervals such as 1 second, 1 minute, and 5 minutes. It also has a built-in 16GB large capacity storage, which can store monitoring data for up to 5 years without frequent exports. Equipped with high-definition LCD display screen, real-time display of current irradiance, historical data curve, environmental temperature, equipment status and other information, intuitive and clear, easy to view on site. Integrated Bluetooth/4G wireless transmission module, monitoring data can be synchronized in real-time to mobile apps or cloud platforms, supporting remote viewing, data export, trend analysis, without the need for on-site device operation. Built in intelligent calibration algorithm, supports one click automatic calibration, and can also be remotely calibrated through the cloud to ensure long-term measurement accuracy and reduce manual calibration costs. At the same time, the device has a data anomaly warning function. When the irradiance data exceeds the normal range or the device malfunctions, an automatic warning message is sent for timely troubleshooting and handling.
