The frequency converter is a power control device that converts the power frequency power source into another frequency by using the on/off function of the power semiconductor device. In the early 21st century, the inverters used mainly used AC-DC-AC (VVVF frequency conversion or vector control frequency conversion). First, the power frequency AC power supply was converted into DC power through the rectifier, and then the DC power was converted into frequency and voltage. Controlled AC power to supply the motor. The circuit of the inverter is generally composed of four parts: rectification, intermediate DC link, inverter and control. The rectification part is a three-phase bridge type uncontrollable rectifier, the inverter part is an IGBT three-phase bridge inverter, and the output is a PWM waveform, and the intermediate DC link is filtering, DC energy storage and buffer reactive power.
Class B temperature rise design, Class F insulation manufacturing.

Monocrystalline Module 72cells 430-460W
Solar Panels collect clean renewable energy in the form of sunlight and convert that light into electricity which can then be used to provide power for electrical loads. Solar panels are comprised of several individual Solar Cells which are themselves composed of layers of silicon, phosphorous, and boron. Solar panels absorb the photons and in doing so initiate an electric current.
