Current no matter from the world or from China, conventional energy resource is all very limited, and the primary energy reserves of China are well below the average level in the world.Solar energy is the inexhaustible renewable energy resources of the mankind, there is the advantages such as the abundance of sufficient spatter property, absolute fail safe, relative popularity, certain long-life and non-maintaining property, resource and economy, in long-term energy strategy, there is critical role.Based on this, photovoltaic generation has become a kind of trend at present.The technical scheme that present photovoltaic generation mostly adopts is, the sun impinges upon on photovoltaic panel, and photovoltaic panel just produces direct current, and this direct current becomes alternating current by inverter.Inverter can be divided into square-wave inverter and sinewave inverter by the output wave mode; The square-wave inverter circuit is simple, and cost is low, but harmonic component is large, be generally used for several hectowatts following and to harmonic requirement not high system.The sinewave inverter cost is high, but goes for various loads.In sum, current photovoltaic generating system is owing to having adopted inverter, so there is following problem: or be that harmonic component is large, or be that cost is high.
Summary of the invention
The purpose of this invention is to provide a kind of generating by solar device, it can solve when utilizing photovoltaic panel to be generated electricity, and the inverter harmonic component is large, the problem that cost is high.
In order to address the above problem, the technical solution used in the present invention is: this generating by solar device, comprise the photovoltaic panel that is provided with terminal box, batteries and controller, the positive pole of described terminal box is connected with the positive pole of the charging input end of described controller, and the negative pole of described terminal box is connected with the negative pole of the charging input end of described controller; The positive pole of the charging output of described controller is connected with the positive pole of the charging end of described batteries, and the negative pole of the charging output of described controller is connected with the negative pole of the charging end of described batteries; The positive pole of the discharge end of described batteries is connected with the positive pole of the electric discharge input of described controller, and the negative pole of the discharge end of described batteries is connected with the negative pole of the electric discharge input of described controller; Also comprise and have a DC motor at least, the positive pole of described DC motor is connected with the positive pole of the electric discharge output of the positive pole of described terminal box and described controller; The negative pole of described DC motor is connected with the negative pole of the electric discharge output of the negative pole of described terminal box and described controller; Motor-driven the turning of described DC motor drive generating.
In technique scheme more specifically scheme can also be: described generator is the AC three-phase generator.
Further: described generator is the AC single phase generator.
Owing to having adopted technique scheme, the present invention compared with prior art, the beneficial effect had is: this generating by solar device is owing to having adopted DC motor directly to be with the motor alternator running, so saved inverter, thereby just there do not is the problem that harmonic component is large, and the production technology of DC motor and alternating current generator is all mature technology, so production cost can be very not high.
The accompanying drawing explanation
Fig. 1 is line schematic diagram of the present invention.
Embodiment
Below in conjunction with drawings and Examples, the invention will be further described:
