MBMet 500 Solar Irradiance Sensor: Accurate and Cost-Effective Measurement for PV Systems
IEC 61000-4-8
(Power Frequency Magnetic Field Immunity Test)
IEC 61000-4-18
(Damped Oscillatory Wave Immunity Test)
The MBMet-500 Series offers cost-effective and accurate measurement of solar irradiance. It provides multiple measurement options and is ideal for monitoring photovoltaic (PV) systems, including both rooftop and ground-mounted installations.
Designed with a sensor element that closely replicates the characteristics of a photovoltaic (PV) module, the sensor delivers a spectral response and incident angle behavior highly comparable to actual PV arrays. This makes the MBMet-500 Series highly suitable for performance monitoring and analysis of PV systems.
The series supports both analog (4–20 mA) and digital (RS-485) output options, ensuring easy integration with a wide range of monitoring and control systems.
