MBMet-700 – Soiling Monitoring Station
IEC 61000-4-8
(Power Frequency Magnetic Field Immunity Test)
IEC 61000-4-18
(Damped Oscillatory Wave Immunity Test)
The MBMet-700 Series Soiling Monitoring Stations provide precise measurement of soiling-related losses on photovoltaic (PV) panels. By calculating key metrics like the Soiling Ratio and Soiling Loss Index, the system enables O&M teams to monitor loss in generation due to dust, pollution, and particulate accumulation—factors that directly affect energy yield and efficiency.Whether deployed in utility-scale solar farms or rooftop PV projects, the MBMet-700 system supports both environments with flexible mounting, robust components, and scalable integration options. It’s engineered for outdoor exposure in remote or grid-connected solar assets, delivering actionable data for scheduling cleaning and optimizing panel performance.The system offers seamless integration with solar SCADA and monitoring tools through multiple communication protocols, including Modbus RTU, Modbus TCP/IP, FTP, SNTP, and cellular connectivity. Equipped with real-time data processing, configurable alerts, and historical data storage, MBMet-700 ensures continuity, transparency, and analytics-readiness for PV operators.
