The built-in solar controller realizes the maximum power point tracking, which can maximize the solar panel output efficiency.

Inverter composition:                                                      

The pure sine wave inverter is roughly assembled by anti-reverse connection protection, boost, rectification and filtering, SPWM controller, and H bridge.         

The square wave inverter has no SPWM controller.

Anti-reverse connection protection: the protection circuit does not work after the input positive and negative poles are connected reversely

Boost: Boost the input low-voltage DC voltage (usually 12V/24V) to more than 300 volts, because the input circuit is relatively large, usually a push-pull architecture; #inverter 20kw single phase          the boost output must be greater than the peak sine wave voltage, for example, the output sine wave voltage is 220V , The boost output must be greater than

Rectification and filtering: rectify and filter the boosted voltage into smooth direct current

SPWM controller: output 4 channels of sine pulse width modulation signal with common ground, and then provided by IR2110 with bootstrap circuit to H bridge to drive 4 MOS

H bridge: with LC filter device to convert 310V DC into myopic sine wave
