6 FAQs about [Anti-reverse current inverter electric complementary without energy storage]

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.

What does reverse current protection protect against?

Reverse current protection is important in distributed, redundant, or hot-swap power supply applications where the loads could potentially force current back into the main bus voltage. It protects against reverse current flow.

How does an anti-reverse current meter work?

Anti-reverse current working principle: Install an anti-reverse current meter or current sensor at the grid connection point. When it detects that there is current flowing to the grid, a signal is sent to the inverter through 485 communication, and the inverter reduces the output power until the reverse output current is zero.

What is reverse current?

Reverse current is where the load attempts to force current back into the power supply source. This can occur when the power supply source is suddenly reduced or completely lost, and the load supply bypass capacitors or batteries attempt to force current back into the power source when first connected.

What is a comparator based n-channel reverse current protection?

Comparator Based N-Channel Reverse Current Protection works by monitoring the voltage difference across a MOSFET under normal positive current flow. The comparator monitors this voltage difference, which is created by a small voltage drop across the MOSFET RDS(on) due to the load current.

What is an anti-reverse connection circuit?

Therefore, the solar system related equipment is generally designed with anti-reverse connection circuits to ensure that the solar equipment is protected from damage when the input power is reversed. The simplest anti-reverse circuit is to connect a diode in series with the input circuit, as shown in Figure 1.
