The power supply of new energy equipment refers to the equipment that provides electricity for new energy equipment (such as solar power generation systems, wind power generation systems, geothermal power generation systems, etc.). These devices typically include inverters, controllers, battery packs, grid connection devices, etc., used to convert solar, wind, geothermal, and other energy collected by new energy devices into electricity and provide it for use in homes, factories, or the power grid. The design of new energy equipment power supply needs to consider the instability and intermittency of renewable energy, as well as the storage and output of electrical energy.
