Jun 3, 2025 · To ensure safety, efficiency, and compatibility with the grid. One such innovation is the anti-backflow function (also known as anti-reverse current protection) in inverters-a key
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.
So the anti-backflow device came into being. The principle of the anti-backflow controller is to control or cut off the output of the grid-connected inverter by monitoring the input power on the grid side, so that the photovoltaic grid-connected power generation system will not feed the grid.
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.
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.
The photovoltaic system with CT (Current Transformer) has anti-backflow function, which means that the electricity generated by photovoltaics is only supplied to loads, preventing excess electricity from being sent to the grid. 2. Why do you need anti-backflow? There are several reasons for installing an anti-backflow prevention solution:
The inverter refers to a component that converts DC to AC. However, after the photovoltaic power generation system is integrated into the grid, it is easy to generate harmonics and three-phase current imbalance, and the randomness of the output power is likely to cause grid voltage fluctuation and flicker.
