Description

Domestic solar power supply unit

Technical field

The utility model belongs to field of solar energy, is specifically related to a kind of domestic solar power supply unit.

Background technology

Solar energy refers to the emittance of sunlight, and the utilization of solar energy has photo-thermal conversion and two kinds of modes of opto-electronic conversion, and solar power generation is a kind of emerging regenerative resource.At present, the utilization of solar energy is not also very universal, utilizes solar power generation also to have the problem that cost is high, conversion efficiency is low, especially in domestic environments.

Utility model content

The utility model, for above-mentioned the deficiencies in the prior art, provides a kind of lower-cost domestic solar power supply unit.

The utility model is achieved by the following technical solution:

A power supply unit, is characterized in that, comprises solar panel, charging distributor circuit, the first batteries, the second batteries, electric discharge distributor circuit, inverter circuit, power supply automatic switchover circuit, 220V civil power and load;

The output of solar panel is connected with the second batteries with the first batteries through charging distributor circuit, the output of described the first batteries and the second batteries is connected with inverter circuit through electric discharge distributor circuit, the output of described inverter circuit is connected with load through power supply automatic switchover circuit, and described power supply automatic switchover circuit is connected with 220V civil power;

Described charging distributor circuit is for to select one mode, the first batteries and the second batteries being charged, and described electric discharge distributor circuit is for discharging to the first batteries and the second batteries to select one mode.

Domestic solar power supply unit described in the utility model is a set of low consumption, the at home uninterrupted formula power supply unit of efficient solar energy.Because solar recharging is slower to battery time, when solar energy is sufficient, only to a batteries charging, and charging current and voltage request undertake by battery charge characteristic, with life-span and the safety of protective current.Another battery pack can be in electricity condition, and can control electric discharge maximum current and maximum voltage well, prevents electric current overdischarge and damages.When battery discharge is when discharging state, automatically switch to charged state while another battery and become discharge condition.This is equivalent to two batteries alternatelies and is recharged, this not only takes full advantage of the solar energy of unit are, has also greatly increased the useful life of batteries, like this in the situation that of equal load, can reduce the requirement to solar cell power output plate, thereby reduce the cost of engineering.

Accompanying drawing explanation

Fig. 1 is the theory diagram of domestic solar power supply unit described in the utility model.

Embodiment

As shown in Figure 1, the utility model provides a kind of domestic solar power supply unit, comprises solar panel, charging distributor circuit, the first batteries, the second batteries, electric discharge distributor circuit, inverter circuit, power supply automatic switchover circuit, 220V civil power and load;

The output of solar panel is connected with the second batteries with the first batteries through charging distributor circuit, the output of described the first batteries and the second batteries is connected with inverter circuit through electric discharge distributor circuit, the output of described inverter circuit is connected with load through power supply automatic switchover circuit, and described power supply automatic switchover circuit is connected with 220V civil power; Described charging distributor circuit is for to select one mode, the first batteries and the second batteries being charged, and described electric discharge distributor circuit is for discharging to the first batteries and the second batteries to select one mode.

Because solar recharging is slower to battery time, when solar energy is sufficient, only to a batteries charging, and charging current and voltage request undertake by battery charge characteristic, with life-span and the safety of protective current.Another battery pack can be in electricity condition, and can control electric discharge maximum current and maximum voltage well, prevents electric current overdischarge and damages.When battery discharge is when discharging state, automatically switch to charged state while another battery and become discharge condition.This is equivalent to two batteries alternatelies and is recharged, this not only takes full advantage of the solar energy of unit are, has also greatly increased the useful life of batteries, like this in the situation that of equal load, can reduce the requirement to solar cell power output plate, thereby reduce the cost of engineering.

Above-mentioned each circuit all can adopt prior art to realize, and in the utility model, repeats no more.The utility model is not only confined to above-mentioned embodiment; persons skilled in the art are according to the disclosed content of the utility model; can adopt other multiple embodiment to implement the utility model; therefore; every employing project organization of the present utility model and thinking; do some simple designs that change or change, all fall into the scope of the utility model protection.
