When it is detected that there is current flowing to the grid (reverse current), the anti-backflow meter transmits the reverse power data to the inverter through RS485 communication.
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.
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.
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.
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.
The PB2200L pumping inverter produced by Shenzhen Solartech Company was used for reverse connection test. Since the inverter has an anti-reverse connection circuit, the anti-reverse diode in the circuit should be short-circuited with a copper wire.
Improve the working efficiency of the whole machine. In order to further reduce the loss caused by the voltage drop of the diode, MOSFET can be used as the switching device in the anti-reverse circuit. As shown in Figure 2, select a MOSFET with a small turn-on voltage drop.
