The utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of photovoltaic generating system that is installed in external wall is provided, it is simple in structure, reasonable in design and result of use is good, this system is applicable to that the southern metope of whole building all installs solar panel, and can the effective and reasonable mains-supplied with this building itself switch, taken full advantage of solar energy resources.
For achieving the above object, the technical solution adopted in the utility model is: a kind of photovoltaic generating system that is installed in external wall, it is characterized in that: comprise the solar battery array group that is installed on the southern metope of building, described solar battery array group is made of the polylith solar panel, described solar battery array group is connected with controller by cable one, described controller is connected with the accumulator array group by cable two and is connected with the combining inverter that the voltage of solar battery array group is adjusted into the 220V alternating current by cable three, described combining inverter connects the architectural power supply electrical network that promising whole building powered by cable six, described accumulator array group is connected by cable four with combining inverter, described cable four is through being used for the switch of control whole piece cable break-make, and described switch and controller join and opening with closure of switch controlled by controller; Described switch is electromagnetically operated valve, and described controller, accumulator array group, switch and combining inverter are installed in the building roof.
Above-mentioned a kind of photovoltaic generating system that is installed in external wall, it is characterized in that: the inside of described controller is equipped with and switches to combining inverter for the electric weight with the solar battery array group and be incorporated into the power networks or switch to the commutation circuit that the accumulator array group is charged, and described controller inside also is equipped with for the judging circuit of differentiating solar battery array group generating voltage.
The utility model compared with prior art has the following advantages:
1, the utility model is simple in structure, reasonable in design and result of use is good.
2, the utility model will be built southern metope solar panel all will be installed, and its energy output is big, and will be very abundant to the utilization of solar energy resources; Meanwhile, the electric weight of solar battery array group is controlled through controller, the trend of its electric weight is respectively the storage of accumulator array group and/or architectural power supply mains supply, when the electric weight of solar battery array group is that whole building is when powering, can carry out the voltage adjustment through combining inverter, whole system is very reasonable, and can very perfectly supply with traditional civil power and carry out combination, and use solar panel electricity amount as much as possible.
3, the utility model is applicable to that the southern metope of whole building all installs solar panel, and can the effective and reasonable mains-supplied with this building itself switch.
Below by drawings and Examples, the utility model is described in further detail.

Embodiment
As shown in Figure 1, the utility model comprises the solar battery array group 2 that is installed on the southern metope of building, described solar battery array group 2 is made of the polylith solar panel, described solar battery array group 2 is connected with controller 3 by cable one 1-1, described controller 3 is connected with accumulator array group 4 by cable two 1-2 and is connected with the combining inverter 5 that the voltage of solar battery array group 2 is adjusted into the 220V alternating current by cable three 1-3, described combining inverter 5 connects the architectural power supply electrical network 6 that promising whole building powered by cable six 1-6, described accumulator array group 4 is connected by cable four 1-4 with combining inverter 5, described cable four 1-4 are through being used for the switch 7 of control whole piece cable break-make, and described switch 7 joins with controller 3 and opening with closure of switch 7 passed through controller 3 controls; Described switch 7 is electromagnetically operated valve, and described controller 3, accumulator array group 4, switch 7 and combining inverter 5 are installed in the building roof.
The utility model, the inside of described controller 3 is equipped with and switches to combining inverter 5 for the electric weight with solar battery array group 2 and be incorporated into the power networks or switch to the commutation circuit that accumulator array group 4 is charged, and described controller 3 inside also are equipped with for the judging circuit of differentiating solar battery array group 2 generating voltages.After accumulator array group 4 is full of electricity, judging circuit is differentiated the generating voltage of solar battery array group 2, when the generating voltage of solar battery array group 2 is lower than set point, controller is connected switch 7, and the electric weight of solar battery array group 2 finally is connected to architectural power supply electrical network 6 by combining inverter 5; When the generating voltage of solar battery array group 2 was higher than set point, controller 3 cut out switch 7, and solar battery array group 2 directly is connected to combining inverter 5 by cable three 1-3, finally inserts architectural power supply electrical network 6.
Operation principle of the present utility model is: will build southern metope solar panel all is installed, its energy output is big, and is very abundant to the utilization of solar energy resources; Meanwhile, the electric weight of solar battery array group 2 is controlled through controller 3, the trend of its electric weight is respectively 4 storages of accumulator array group and/or 6 power supplies of architectural power supply electrical network, when the electric weight of solar battery array group 2 is that whole building is when powering, can carry out the voltage adjustment through combining inverter 5, whole system is very reasonable, can very perfectly supply with traditional civil power to switch, and use solar panel electricity amount as much as possible.
The above; it only is preferred embodiment of the present utility model; be not that the utility model is imposed any restrictions; every according to the utility model technical spirit to any simple modification, change and equivalent structure transformation that above embodiment does, all still belong in the protection range of technical solutions of the utility model.
