AGF-M Perforation type PV confluence acquisition device is specially designed for smart PV combiner box. It is used for monitoring the running state of solar panels in solar cell arrays, measuring the currents of solar cell, detecting the state of surge protection devices and DC breaker. The device is equipped with RS485(Modbus) communication port for transmitting all the datas to master device.
