The control design of this type of inverter may be challenging as several algorithms are required to run the inverter. This reference design uses the C2000 microcontroller (MCU) family of devices to implement control of a grid connected inverter with output current control.
4. The solution? Deye inverter anti-backflow working principle: install an meter with CT or current sensor at the grid-connected point. When it detects that there is current flowing to the grid, it will feed back to the inverter, and the inverter will immediately change its working mode and track from the maximum power point of MPPT.
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.
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.
