Description

technical field [0001] The invention relates to the technical field of solar energy and wind energy power supply systems and control systems, in particular to a modularized intelligent household wind and solar complementary off-grid power supply system. Background technique [0002] The existing household wind-solar hybrid power supply system mainly uses a dedicated PWM control chip to perform DC / DC conversion on the output power of solar panels and wind turbines to charge the battery; the computer output part of the power supply system mainly uses an inverter to convert the power of the battery The DC power is inverted to AC power, which then supplies power to the load. The existing structure has been unable to meet the application requirements when dealing with diversified needs, such as the expansion of hardware circuits such as photovoltaic modules, fan capacity, battery modules, DC / DC converters, and intelligent monitoring of the parameters of each component. At the sa...
