4 FAQs about [Installation of photovoltaic panel anti-backflow device]

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?
