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.
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.

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.
For example, solar controllers such as grid-connected inverters, off-grid inverters and pumping inverters will connect electrolytic capacitors in parallel on the DC input side to support the DC voltage.
The photovoltaic inverter and the anti-reverse current meter have been matched through the protocol. During the on-site installation, the anti-reverse current meter is connected to the RS485
