Does a photovoltaic system have anti-backflow?
The 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:
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.

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.
How does a photovoltaic power system work?
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.
What is countercurrent in a photovoltaic power station?
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?
