This solar irradiance meter is both accurate and user-friendly, making it ideal for essential measurements in the installation, testing, maintenance, and reporting of solar panels or photovoltaic systems. Furthermore, it seamlessly integrates wirelessly with the SMFT-1000 solar multifunction PV analyzer, enabling instant determination of the I-V curve for tested panels.
Durable and portable, this irradiance meter features a high-contrast LCD screen that is easily readable even in direct sunlight, making it convenient to carry wherever you go. Thanks to its straightforward user interface and incorporated temperature sensor, it effortlessly complies with the IEC 62446-1 standard for testing, documenting, and maintaining photovoltaic systems. The built-in compass and inclination sensor also enable swift measurement and documentation of roof and site orientation, pitch, and panel tilt during surveys, installations, or adjustments.
