Solar household low-voltage DC power supply system

Abstract

The invention provides a solar household low-voltage DC power supply system, which comprises a solar energy collection mechanism, a power storage mechanism, a control mechanism and a power output mechanism, wherein the solar energy collection mechanism is used for collecting solar energy and converting the solar energy into electric energy; the power storage mechanism is used for storing the electric energy which is collected and converted by the solar energy collection mechanism; the power output mechanism is used for outputting the power of a storage battery outwards and is matched with a household electric circuit; and the control system controls operation of the system. The system can also comprise an electric supply charging circuit; and when a photovoltaic panel does not have electric energy to output, the charging circuit is automatically switched to convert electric supply into a low-voltage DC through the power storage mechanism, and supplies the low-voltage DC to a family for use through the power output mechanism. According to the system, utilization of the solar energy by the family can be improved; application of the electric supply is partially replaced; the electric supply can also be converted into a DC power supply for the family through the system; consumption of the electric supply is greatly reduced; energy conservation and emission reduction are achieved; and the mankind is benefited.

Description

technical field [0001] The invention relates to the field of solar energy, in particular to a low-voltage direct current power supply system for solar households. Background technique [0002] Now the 220V AC power provided by the power supply bureau to the family needs to be converted into DC power to power household appliances. This method is very cumbersome, and the most common way is to use a power adapter. These ubiquitous small boxes are now cheap and light, but they are usually inefficient, turning electricity into heat and wasting it, and this kind of equipment will continue to run day and night, regardless of the price of electricity, consuming a lot of electricity . [0003] And now family is often limited to solar water heaters to the utilization of solar energy, namely heat supply with solar energy, has not generally developed to heat supply and power supply with solar energy. Contents of the invention [0004] In view of the above problems, in order to make ...

Problems solved by technology

These ubiquitous small boxes are now cheap and light, but they are usually inefficient, turning electricity into heat and wasting it, and this kind of equipment will continue to run day and night, regardless of the price of electricity, consuming a lot of electricity

[0003] However, the use of solar energy in households is often limited to solar water heaters, that is, heating with solar energy, and it has not been generally developed to use solar energy for heating and power supply.
