Embodiment
The purpose of this utility model provides a kind of from net type photovoltaic control energy storage electric power system, should be higher to the utilance of electric energy from net type photovoltaic control energy storage electric power system.
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is carried out clear, complete description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, all other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belong to protection range of the present utility model.
Please refer to Fig. 1 and Fig. 2, the structural representation that Fig. 1 is provided for the utility model embodiment from net type photovoltaic control energy storage electric power system; Fig. 2 is the partial enlarged drawing at A position among Fig. 1.
Provided by the utility model from net type photovoltaic control energy storage electric power system, comprise photovoltaic module 11, control system 12, energy storage battery 13, install bin 14, electrical appliance 2 and support 3.Photovoltaic module 11 is installed on the top of install bin 14, configures the angle between photovoltaic module 11 and the install bin 14 when mounted, thereby the photoelectric conversion efficiency of feasible photovoltaic module 11 in net type photovoltaic control energy storage electric power system is higher; Certainly can also be connected photovoltaic module 11 on the upper surface of install bin 14 by ball pivot, so just can be according to the difference of different regional lighting angles, thereby by rotating the angle that photovoltaic module 11 changes between photovoltaic module 11 and the install bin 14, and then the photoelectric conversion efficiency of feasible photovoltaic module 11 in net type photovoltaic control energy storage electric power system is higher, and the feasible like this range of application from net type photovoltaic control energy storage electric power system is wider; Control system 12 is installed in the install bin 14 with energy storage battery 13, is electrically connected by control system 12 realizations between energy storage battery 13 and the photovoltaic module 11.Install bin is fixed in the top of support 3, and electrical appliance 2 is realized being electrically connected with the energy storage battery 13 of generating and energy storage device.
By above-mentioned structure from net type photovoltaic control energy storage electric power system as can be known, when this system is in the electrification energy storage process, photovoltaic module 11 is an electric energy with solar energy converting, charge by 12 pairs of energy storage batteries 13 of control system, the electric energy that will be come by transform light energy is stored in the energy storage battery 13; And because photovoltaic module 11 is installed on the install bin 14, control system 12 is installed in the install bin 14 with energy storage battery 13, thereby make photovoltaic module 11 shorter to the circuit between the energy storage battery 13, shortened the length of support 3 than prior art, reduced electric energy loss on the line, also, therefore improved the utilization rate of electrical of solar photovoltaic powered system significantly because control the system that the energy storage electric power system is small-power generating, electricity consumption substantially from net type photovoltaic.
