FAQ About Anti-backflow

Q: What is PV anti-backflow? A: In a PV system, when the generated power is greater than the user-side demand – meaning the load is unable to consume all the energy produced – the excess power flows to the grid. Since this current flows in the opposite direction to the conventional one, it is referred to as „countercurrent."

3 FAQs about [User-side energy storage 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:

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
