What is a photovoltaic system with anti-backflow?
The photovoltaic system with anti-backflow is that the electricity generated by the photovoltaic is only used by the local load and cannot be sent to the grid. When the PV inverter converts the DC point generated by the PV modules into AC power, there will be DC components and harmonics, three-phase current imbalance, and output power uncertainty.
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.
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.
Why do photovoltaic power generation systems need anti-reverse flow equipment?
If there are many such power generating sources to transmit electricity to the power grid, the power quality of the power grid will be seriously degraded. Therefore, this type of photovoltaic power generation system must be equipped with anti-reverse flow equipment to prevent the occurrence of reverse power. How does backflow prevention work?
Is a photovoltaic grid connected system an anti-reverse current generation system?
The power grid company requires the photovoltaic grid-connected system to be built later to be an anti-reverse current generation system. What is anti-backflow? What is "countercurrent"? In the power system, the power is generally sent from the grid to the load, which is called forward current.
How does anti-backflow work?
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?
