Inverter, also known as power regulator and power regulator, is an essential part of photovoltaic system. The main function of the photovoltaic inverter is to convert the direct current generated by the solar panel into the alternating current used by home appliances. All the electricity generated by the solar panel must be processed by the inverter before it can be output.  Through the full-bridge circuit, the SPWM processor is generally used for modulation, filtering, boosting, etc., to obtain a sinusoidal AC power that matches the lighting load frequency and rated voltage for use by system end users. With the inverter, DC batteries can be used to provide AC power to electrical appliances.
The solar AC power generation system is composed of solar panels, charge controllers, inverters and batteries; the solar DC power generation system does not include inverters. The process of converting AC power into DC power is called rectification, the circuit that completes the rectification function is called a rectifier circuit, and the device that implements the rectification process is called a rectifier or rectifier. Correspondingly, the process of converting DC electric energy into AC electric energy is called inverter, the circuit that completes the inverter function is called inverter circuit, and the device that realizes the inverter process is called inverter equipment or inverter. The core of the inverter device is the inverter switch circuit, referred to as the inverter circuit for short. This circuit completes the function of inverter by turning on and off the power electronic switch. The on-off of power electronic switching devices requires certain driving pulses, which may be adjusted by changing a voltage signal. The circuit that generates and regulates the pulse is usually called a control circuit or control loop. The basic structure of the inverter device, in addition to the above-mentioned inverter circuit and control circuit, there are protection circuits, output circuits, input circuits, output circuits, etc.
Due to the diversity of buildings, it is bound to lead to the diversity of solar panel installation, in order to maximize the conversion efficiency of solar energy
At the same time, taking into account the beautiful appearance of the building, this requires the diversification of our inverters to achieve the best way of solar energy conversion.
