The AGF-T Series is a high-performance perforation type PV confluence acquisition device developed for smart photovoltaic combiner boxes. It provides accurate real-time monitoring of multiple PV string currents, busbar voltage, surge protection device status, DC breaker condition, and internal temperature. With up to 24 input channels, programmable RS485 Modbus communication, and LCD display options, AGF-T ensures reliable data collection and transmission to centralized monitoring systems. It is ideal for solar farms, distributed PV arrays, and intelligent solar management solutions.
