Can the anti-reverse current grid-connected inverter be used

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.

What happens if solar power input is reversed?

If the solar power input is reversed, the power will form a short circuit through the anti-parallel diode. According to the characteristics of the solar module, the voltage of the solar power supply When pulled down, the voltage value is only the sum of the forward voltage drop of the two diodes, which will not damage the electrolytic capacitor.

What is the simplest anti-reverse diode circuit?

The simplest anti-reverse circuit is to connect a diode in series with the input circuit, as shown in Figure 1. In applications with lower input voltage, Schottky diodes can be used to reduce the loss due to tube voltage drop. Improve the working efficiency of the whole machine.

How to choose a MOSFET anti-reverse circuit?

Choosing a MOSFET device with a smaller on-resistance can significantly reduce the loss caused by the anti-reverse circuit. However, as the voltage level increases, this solution has a lower cost performance compared with the diode solution. Figure 2 MOSFET anti-reverse circuit
