Why should you use an anti-backflow solution for energy storage systems?
During the discharge process of industrial and commercial energy storage systems, due to power fluctuations, changes in load power consumption and other reasons, reverse flow of electrical energy may also occur. The anti-backflow solution can effectively avoid this problem and ensure the safe and efficient operation of the energy storage system.
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.
Does energy storage have a backflow problem?
As the scale of global industrial and commercial electricity consumption continues to expand, industrial and commercial energy storage technology has attracted more and more attention. The backflow problem in energy storage systems has always been a problem that troubles users.
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 should I install an anti-backflow prevention solution?
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.
