Embodiment Construction

[0014] One of the core concepts of the embodiments of the present invention is to provide a solar direct current power supply station, which uses solar power generation as the main power supply source, and utilizes the direct current output by the solar energy to provide electric energy for direct current loads. At the same time, because the solar power generation system is affected by factors such as seasons, day and night, and cloudy weather, when solar power generation cannot meet the needs of household loads, the mains power is used to supplement the battery to ensure that the battery is used for household loads, especially household lighting systems. Provide continuous and stable DC power.

[0015] refer to figure 1 , shows a structural block diagram of an embodiment of a solar direct current power supply station in the present invention, including: a solar photovoltaic cell 11, a solar power generation controller 12, a storage battery 13, a complementary charging contro...

Abstract

The invention provides a solar direct-current supply station which comprises a solar photovoltaic battery, a storage battery, a solar electricity-generating controller, a complementation charging controller, a mains supply charging module, a storage battery discharging module and a direct-current load. The solar electricity-generating controller is used for adjusting and controlling electric energy converted by the solar photovoltaic battery, sending the adjusted energy to the direct-current load on one hand, and sending the excess energy to the storage battery for storing on the other hand. When electricity generated by the solar photovoltaic battery can not meet the need of the direct-current load, the controller sends the electric energy of the storage battery to the direct-current load through the discharging module. The complementation charging controller is used for controlling the mains supply charging module to charge the storage battery when the electric energy of the storage battery is insufficient, and therefore the storage battery can supply direct currents continuously to the direct-current load. The solar direct-current supply station can provide the stable and continuous direct currents for villages, pasturing areas, mountainous areas and the like where power supply of a public power grid is unstable, and illumination and life of users are facilitated.

Description

technical field [0001] The invention relates to the technical field of solar energy applications, in particular to a solar direct current power supply station. Background technique [0002] Solar power generation is a device that uses battery components to directly convert solar energy into electrical energy. In areas where the stability of the vast power grid is insufficient, the device can conveniently realize lighting and power supply for users. [0003] The traditional solar power generation system mainly includes: solar photovoltaic cells, solar power generation controllers, storage batteries, inverters, and user lighting loads. Among them, the solar photovoltaic cells and batteries are the power supply system, the controller and inverter are the control protection system, and the load is the system terminal. Specifically, the solar power generation controller regulates and controls the generated electric energy. On the one hand, the adjusted energy is sent to the DC ...
