Get StartedThe 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:
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.
There are several reasons for installing an anti-backflow prevention solution: 2.1.Limited by the capacity of the upper-level transformer, users have new grid system installation needs, but it is not allowed locally. 2.2.Due to some regional policies, grid connection is not allowed. Once it is found, the grid company will impose a fine.
In a power system, power is generally sent from the grid to the load, which is called forward current. After installing a photovoltaic power station, when the power of the pv system is greater than that of the load, the power that cannot be consumed will be sent to the grid.
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:
After installing a photovoltaic power station, when the power of the pv system is greater than that of the load, the power that cannot be consumed will be sent to the grid. Since the current direction is opposite to the conventional one, it is called “countercurrent". 1. What is anti-backflow?
