Solar domestic autonomous power supply system

Abstract

The invention discloses a solar domestic autonomous power supply system. The system comprises a solar power supply device, and a total control device. The solar power supply device comprises a solar energy power source, an inverter transformer, a solar power supply device control module, an electric quantity detection module, a light intensity detection module and a motion module; the solar energypower source is arranged at the upper portion of the solar power supply device, the inverter transformer supplies power to household appliances; the electric quantity detection module detects the electric quantity; the light intensity detection module detects the light intensity of the sunlight the total control device coordinates and controls the solar power supply device; the solar power supplydevice control module receives the signals of the electric quantity detection module and controls the power supply mode and the power supply state of the solar power supply device, the motion moduleis moved into a set area range according to the control command of the solar power supply device control module, and when the solar power supply device is under the sunlight, the solar energy power source performs charging. The solar domestic autonomous power supply system has the beneficial effects of autonomous charging, and energy conservation and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of power supply, and in particular relates to a solar household autonomous power supply system. Background technique [0002] In the field of urban power supply, especially in summer, when the power consumption is high, the problem of power supply shortage becomes more and more prominent. Therefore, it is more urgent to replace the traditional power supply mode with new energy power supply. [0003] Existing solar power plants need to occupy a large area of ​​land, and solar power plants need to build long-distance transmission lines when connected to the grid, resulting in a large amount of power transmission loss, especially when the distance between the solar power plant and the city that uses electricity is far away, the cost of the transmission line is high, and the photoelectric conversion efficiency Low. Existing decentralized collection of solar photoelectric conversion electric energy or solar pho...

[0003] Existing solar power plants need to occupy a large area of ​​land, and solar power plants need to build long-distance transmission lines when connected to the grid, resulting in a large amount of power transmission loss, especially when the distance between the solar power plant and the city that uses electricity is far away, the cost of the transmission line is high, and the photoelectric conversion efficiency Low

Existing decentralized collection of solar photoelectric conversion electric energy or solar photothermal conversion electric energy to obtain electric energy, because it cannot be transported to the grid-connected power station, it cannot realize large-scale grid-connected power generation, which limits the utilization of solar energy
