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.
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.
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.
If the generation exceeds the consumption, the surplus electricity flows back into the grid, creating backflow. Systems with anti-backflow functionality can adjust the inverter''s output to ensure that the electricity generated is fully consumed by local loads, preventing excess power from entering the grid. Why Install Anti-Backflow?
Our standardized container products are engineered for reliability, safety, and easy deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
