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:

What is a blocking diode in a solar photovoltaic array?

Blocking diodes are basically used in solar photovoltaic arrays when there are two or more parallel branches, or there is a possibility that some of the array will become partially shaded during the day as the sun moves across the sky. The size and type of blocking diode used depend upon the type of solar photovoltaic array.
