4 FAQs about Price of solar panel power generation anti-backflow device

How a photovoltaic system is anti-backflow?

According to the requirements of the domestic Golden Sun Project for grid-connected photovoltaic systems, the photovoltaic system on the user side must be spontaneous and self-use. So the anti-backflow device came into being.

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 does Deye inverter anti-backflow work?

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 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?
