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.

What is an anti-backflow controller?

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.

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.

What is a photovoltaic inverter?

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.

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.

How is the inverter controlled?

At the same time, according to the data read from the measurement and control instrument, the inverter of the four slave stations is controlled through the MODBUS communication Swit ch on and off. The last slave station PLC uses MODBUS to communicate with the monitoring terminal for data and status.
