The power electronic power devices used in photovoltaic inverters are mainly IGBT transistors, SIC MOSFETs, CoolMoss, and SiC MosFETs from a single transistor perspective. In terms of modules, there are PrimePack series, Econal series, white modules, and so on. In addition, other chips used in photovoltaic inverters include control chips, power related chips, other digital and analog chips, and auxiliary power management chips.

MCU and MPU are the main parts used for control chips in photovoltaic inverters, which correspond to ARM control chips in two categories. MCU is used for data collectors and other equipment, while MPU is used for inverter battery management systems and bidirectional converters. The DSP series should use second-generation DSP chips for small inverters and inverters, while the power drive should use mid to low-end chips that are relatively cost-effective within the third-generation DSP. Large inverters and inverters should use high-end chips from the third-generation DSP.

The photovoltaic inverter made ten years ago used silicon carbide diodes to complete string inverters and other centralized inverters. The photovoltaic inverters used today include the largest single unit SG320HX, which can be matched with large components and has lower electricity costs. The current inverter can increase power density by 80%, but the cost has decreased by 80%.
