Application of bidirectional energy meter in PV solar energy metering

The photovoltaic power generation system will send excess energy to the grid while supplying power to the AC load; When the sunshine is insufficient, that is, when the solar array cannot provide enough electricity for the load, it can obtain electricity from the grid to supply power to the load. So it is necessary to use bidirectional energy meter.

What is a bidirectional energy meter?

Bidirectional meter is a meter that can measure electricity consumption and generation. Power and electric energy are directional, the meter can distinguish the measurement of forward and reverse electricity, bidirectional metering function has also become a necessary condition for V2G charging pile.
