AGF-M Series DC Monitoring Device for Solar Strings
AGF-M perforation type PV confluence detection device is specially designed for intelligent PV combiner box. It is used to monitor the working status of solar modules in solar cell arrays, measure the currents of solar cells, detect the status of surge protection devices and DC breakers. The device is equipped with RS485 (Modbus) communication port, where all data can be transmitted to the master device. Acrel AGF-M solar DC string monitoring device measures DC current in up to 24 circuits (with Hall sensors); busbar voltage, paired with PV combiner box to monitor DC multi-circuits
