6 FAQs about [Energy storage system anti-backflow]

How do photovoltaic anti-backflow systems work?

According to different system voltage levels, photovoltaic anti-backflow systems can be divided into single-phase anti-backflow systems, three-phase and energy storage system ones. In a power system, power is generally sent from the grid to the load, which is called forward current.

Why is anti-backflow protection important?

For PV projects designed for self-consumption without grid feeding, anti-backflow protection is crucial for achieving sustainable energy independence. What Is Anti-Backflow? In a PV system, the solar modules produce direct current (DC), which is converted to alternating current (AC) by an inverter to supply local loads.

What are anti-backflow solutions?

Summary Anti-backflow solutions address the "grid-connected but non-feed-in" policy requirements of specific regions. They enhance grid stability, improve system safety, optimize energy efficiency, and adapt to evolving technologies and policies.

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.

How does a Deye inverter anti-backflow work?

4. The solution? Deye inverter anti-backflow working principle: install an meter with CT or current sensor at the grid-connected point. When it detects that there is current flowing to the grid, it will feed back to the inverter, and the inverter will immediately change its working mode and track from the maximum power point of MPPT.

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:
