How does an inverter achieve anti-backflow?

Upon detecting current flow towards the grid, the inverter will reduce its output power until the countercurrent is eliminated, thereby achieving anti-backflow. It is important to note that the CT and meter themselves do not have anti-backflow capabilities; they simply collect data to enable the inverter to adjust its output accordingly.

Why is anti-backflow referred to as countercurrent?

Since this current flows in the opposite direction to the conventional one, it is referred to as “countercurrent.” Q: Why is anti-backflow needed? A: There are several reasons to prevent excess electricity generated by the PV system from flowing into the grid:

How to use anti-backflow function in ECU-C local network interface?

Anti-backflow function can be opened or closed in the ECU-C Local Network Interface like figure 3.In this interface you can also set power limit from 0 to a certain positive number. The power limit means that anti-backflow function works only when the backflow occurs and the backflow power is greater than the power limit.

What is reverse power relay (RPR) for solar?

Reverse power relay (RPR) for solar is used to eliminate any power reverse back to gird from an on-grid (grid-tie) PV power plant to the grid or to the generator by tripping either on-grid solar inverter or breaker or any contactor depending upon the type of power distribution and a control circuit.

Do CT meter and meter have anti-backflow capabilities?

It is important to note that the CT and meter themselves do not have anti-backflow capabilities; they simply collect data to enable the inverter to adjust its output accordingly. Senergy Single-Phase Residential Anti-Backflow Solution
