Acrel AGF-AE Series PV/Solar Inverter meter is a single-phase three-wire solar energy meter specially designed for the Americas. It is suitable for solar photovoltaic systems and is used in conjunction with inverters to measure the AC power parameters in the loop, so as to achieve the function of power monitoring.

The photovoltaic system is generally composed of solar photovoltaic panels, photovoltaic inverters, smart meters, and battery components. The solar meters are divided into three parts in the entire system. 1: Between the inverter and the load, it is used to measure the total power generation of the photovoltaic system. 2: Between the load and the national grid meter, it is mainly used to measure the power on and off the grid to prevent backflow. 3: DC meter, installed between the inverter and the battery,: measuring the charge and discharge data of the energy storage module.
The power meter needs to work with inverter, inverter read the power and direction of the load through RS485. Then adjust output power in order to realize power function.
The power meter itself cannot prevent reverse power and needs to be uesd in conjunction with the inverter.
Inverter can connect the same meter data through gateway, this function requires the inverter manufacturer to debug.
PV meter is used for energy storage judgment, power consumption analysis, and anti-backflow functions of photovoltaic systems.
