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.
When reverse current is detected, the meter communicates the backflow data to the inverter via RS485 communication. The inverter responds within seconds, reducing its output power to ensure the current flow into the grid is nearly zero. Anti-Backflow Solutions Different configurations are available to meet various scenarios:
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. Thereby, the anti-reverse flow function is realized.
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.
