In the utility model, solar energy is transmitted to the storage cell through the controller and stored in the storage cell, and when the load needs to consume power, a direct current is converted into an alternating current by the two-way inverter and supplied to the load for use; when electric energy stored in the storage cell can not satisfy the demand of the load, the two-way inverter automatically switches to the commercial power, and the commercial power supplies power to the load; and when the storage cell is fully charged by the solar cell, power from the solar cell panel can be transmitted to the power grid by the two-way inverter and supplied to other users. The intelligent double-line inversion mode greatly enhances the utilization ratio and stability of the system.

Description

A kind of photovoltaic generating system
Technical field
The utility model relates to the solar cell power generation field, specifically is a kind of photovoltaic generating system.
Background technology
Solar cell is a kind of solar radiant energy to be directly changed into the novel power supply of electric energy, has permanent, spatter property and advantages such as spirit and type, now solar energy generation technology is had more deep research both at home and abroad, and in the use, also be that many formulas are various; From little to the electronic product electricity consumption, all utilizing solar cell power generation production, life etc. to large-scale power station greatly.
The independent luminous volt generating of tradition is according to average sunshine time, average overcast and rainy continuously estimate solar panel size, battery capacity, if capacity is little, can influence power demands, if volume calculation is big, can cause certain waste; Battery capacity that is difficult to estimate in the independent photovoltaic generating and the continuous overcast and rainy days that is difficult to estimate; And the technology of the photovoltaic generation of non intelligentization and civil power switching.
The utility model content
Limited for the regulating power that solves existing photovoltaic generation, cause energy waste easily, the utility model provides a kind of photovoltaic generating system.
The technical scheme that the utility model adopts is: said system comprises solar cell, controller, storage battery and two-way inverter; Said solar cell is connected with two-way inverter through controller; Said two-way inverter selectively is connected with civil power or load electricity consumption, and said controller also is connected with two-way inverter through storage battery.
Preferably, said controller is a controller for solar.
Preferably, said load electricity consumption comprises family expenses electrical network and high-voltage fence.
Preferably, said storage battery is a chargeable storage.
The utility model is transferred to solar energy in the storage battery through controller and stores, and in the time of the need of load electricity consumption, converts direct current into the alternating current supply load through two-way inverter and uses; Because load is indefinite service time, therefore when the electric energy that stores in the storage battery can't satisfy need of load, two-way inverter automatically switched to civil power, is used by the civil power supply load; When solar cell electricity battery capacity expired, solar panel sends electric availablely was transported to electrical network through two-way inverter, supplies with other users' uses; The intelligent two-wire inverting of this kind has improved the utilance and the stability of system greatly.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model.
In the drawings, 10 solar cells, 11 controllers, 12 storage batterys, 13 two-way inverters, 14 civil powers, 15 load electricity consumptions.
Embodiment
Below in conjunction with accompanying drawing the embodiment that the utility model provides is described in further detail:
As shown in Figure 1; Structural representation for a kind of embodiment of the utility model; This system comprises solar cell 10, controller 11, storage battery 12 and two-way inverter 13; Said solar cell 10 is connected with two-way inverter 13 through controller 11, and said two-way inverter 13 selectively is connected with civil power 14 or load electricity consumption 15, and said controller 11 also is connected with two-way inverter 13 through storage battery 12.The utility model is transferred to solar energy in the storage battery through controller and stores, and in the time of the need of load electricity consumption, converts direct current into the alternating current supply load through two-way inverter and uses; Because load is indefinite service time, therefore when the electric energy that stores in the storage battery can't satisfy need of load, two-way inverter automatically switched to civil power, is used by the civil power supply load; When solar cell electricity battery capacity expired, solar panel sends electric availablely was transported to electrical network through two-way inverter, supplies with other users' uses; The intelligent two-wire inverting of this kind has improved the utilance and the stability of system greatly.The utility model design is to adopt Automatic Control, need not manual maintenance; Inverter have anti-overcharge, kinds of protect function such as overdischarge, current-limiting protection and require the photovoltaic electricity consumption and civil power automaticallyes switch, lack switching time, can satisfy the demand of load fully.
Consult Fig. 1 once more; After the solar cell 10 of this embodiment received the emittance of sunlight, (DC) was delivered to controller 11 with digital signal, can through the opto-electronic conversion output DC; Passing through under the effect of controller for solar 11; In storage battery 12, preferably, said storage battery is a chargeable storage with electrical power storage.Controller 11 has anti-overcharging and the maximum functional point function of tracking solar battery.When storage battery 12 voltages greater than set point, stop storage battery 12 charging or be in floating charge state, the electric energy that solar cell 10 sends (analog signal AC) is transferred in the utility network through two-way inverter 13; When load electricity consumption 15 needed electricity consumption, two-way inverter 13 detected the voltage of storage batterys 12, when the voltage of storage battery 12 in setting range, then storage battery 12 converts direct current into alternating current through two-way inverter 13, is transferred to AC load 15 electricity consumptions; When the electric quantity consumption in the storage battery 12 arrived set point, two-way inverter 13 automatically switched to civil power 14; Give the load electricity consumption 15 power supplies by civil power 14, two-way inverter 13 quits work; When the electric weight in the storage battery 12 returned to set point, two-way inverter 13 switched to storage battery 12 tunnel with civil power 14 again, gave the load electricity consumption 15 power supplies by storage battery 12; Have suffered switching time in the ms level, do not influence the load operate as normal; The load electricity consumption of the utility model comprises family expenses electrical network and high-voltage fence, switches in the different load electricity consumptions according to actual conditions respectively.
Therefore if this system runs into continuously the overcast and rainy long or interim power consumption of load when bigger, photovoltaic power supply and civil power are switched mutually, reach energy-conservation effect; Present stage is because the batteries to store energy technology is also very ripe, and the energy storage cost also compares higherly, therefore can consider to reduce battery capacity so also to have reduced cost of investment when design drops in early stage; This system belongs to automatic control to be switched, so after installation, need not people's management.
