How does an anti-backflow inverter work?

If any energy feeding into the grid is detected, the anti-backflow device immediately provides feedback to the inverter. The inverter then quickly reduces its output power, achieving a state of zero feeding to the grid. This function is critical for maintaining the safety and compliance of PV systems in regions with strict regulations.

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.

How does a grid-connected inverter work?

Install a CT (Current Transformer) or meter on the grid-connected busbar to monitor real-time current direction and magnitude, which is then communicated to the inverter. Upon detecting current flow towards the grid, the inverter will reduce its output power until the countercurrent is eliminated, thereby achieving anti-backflow.

Why should I install anti-backflow?

The main reasons for installing anti-backflow include: 1. Grid Policy Restrictions: In some regions, grid constraints or policies prohibit feeding power into the grid. Unauthorized backflow may lead to penalties. 2. Grid Connection Limitations: The grid imposes strict limits on the amount of power that can be fed into it.

What is an anti-backflow meter?

The anti-backflow function is specifically designed to prevent this reverse energy flow. Its purpose is to safeguard both the PV system and the grid infrastructure from potential issues caused by unintended power feeding. To achieve this, an intelligent meter is usually installed on the AC side of the system.
