Abstract
The utility model discloses an AC type solar energy photovoltaic module, which comprises a miniature inverter and a photovoltaic junction box integrated into one body to form an AC junction box, wherein two lead-out leads of an output end of the photovoltaic junction box are connected to an input end of the miniature inverter; and the AC junction box is mounted on a backboard of the solar energy photovoltaic module. The utility model is reasonable in structure and convenient in maintenance; each module directly outputs alternating current, and maximum power point tracking is achieved on each module, when installing the system, centralized junction and inversion are not needed, the module can be used independently and can also be used to form a large-capacity photovoltaic system. Each module is independent by employing the design, the system installation is simple and convenient, the expansion capability and risk resistance capacity of the system are strong, if an individual module goes wrong, normal running of the whole system will not be affected, and the improvement is obvious compared with the existing photovoltaic modules.
Description
Technical field:
The utility model relates to a kind of solar photovoltaic assembly.
Background technology:
At present, known solar photovoltaic assembly is output as direct current, when installing in system, need make solar photovoltaic assembly connect into photovoltaic array by series connection and mode in parallel, output with photovoltaic array puts together the access inverter then, obtains exchanging output through inverter.Such system's cabling complexity is lengthy and tedious, and the maximal power tracing of inverter is based on the overall optical photovoltaic array, if have individual component to have foreign matter to block or when having other faults to occur, the inverter maximal power tracing will be adjusted the output of overall optical photovoltaic array, like this, the fault of one block assembly may cause the output of whole system to reduce greatly, and the inverter of high power capacity, the components and parts life-span is shorter, troublesome maintenance, in case break down, with the normal operation of the whole photovoltaic system of influence.
Summary of the invention:
The purpose of this utility model is to provide AC type solar photovoltaic assembly a kind of rational in infrastructure, easy to maintenance.
Technical solution of the present utility model is:
A kind of AC type solar photovoltaic assembly, comprise miniature inverter, photovoltaic junction box, it is characterized in that: miniature inverter, photovoltaic junction box become one, and form to exchange terminal box, and wherein two of the outputs of photovoltaic junction box are drawn the input that lead inserts miniature inverter; Exchanging terminal box is contained on the backboard of solar photovoltaic assembly.
Miniature inverter is positioned at the below of photovoltaic junction box.
Under the interchange terminal box, the support bar that is fixed on the back panel of solar photovoltaic module is set, and the interchange terminal box is supported on the support bar.
Be provided with air duct between the miniature inverter of interchange terminal box and the backboard of solar photovoltaic assembly.
Miniature inverter adopts the embedding form.
The utility model is rational in infrastructure, and is easy to maintenance; The direct output AC of every block assembly, and MPPT maximum power point tracking is all arranged above every block assembly, when installing, needn't concentrate and conflux and inversion in system, can independently use also and can form jumbo photovoltaic system.Such design makes every block assembly all independent, and system installs simple and convenient, and the expandability and the ability to ward off risks of system are strong, if there is individual component to break down, will can not influence the normal operation of whole system, and comparing present photovoltaic module has all had raising.
Description of drawings:
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the configuration diagram of an embodiment of the utility model.
Fig. 2 is the connection diagram of miniature inverter and photovoltaic junction box among Fig. 1.
Fig. 3 is the connection diagram of miniature inverter and aluminium alloy post.
1. photovoltaic junction boxes among the figure, 2. miniature inverter, 3. aluminium alloy support bar, 4. screw, 5. self-clinching stud, 6. backboard.
Embodiment:
A kind of AC type solar photovoltaic assembly comprises miniature inverter, photovoltaic junction box, and miniature inverter, photovoltaic junction box become one, and forms to exchange terminal box, and wherein two of the outputs of photovoltaic junction box are drawn the input that lead inserts miniature inverter; Exchanging terminal box is contained on the backboard of solar photovoltaic assembly.Be called the AC photovoltaic module.
In Fig. 1, miniature inverter 2 is installed in the below of photovoltaic junction box 1, in order to bear the weight of miniature inverter 2, an aluminium alloy support bar 3 is installed again in the middle of assembly.
Among Fig. 2, the contact portion between miniature inverter 2 and the photovoltaic junction box 1 respectively has two circular holes, and miniature inverter 2 circular holes are alignd with photovoltaic junction box 1 circular hole, and both sides are respectively squeezed into two screws 4 and fixed miniature inverter 2 and photovoltaic junction box 1.The output of photovoltaic junction box 1 is drawn the input that two leads insert miniature inverter 2; through miniature inverter 2 output ACs; miniature inverter 2 adopts the embedding design; the components and parts in the miniature inverter 2 so both can have been protected; can improve the heat dispersion of miniature inverter 2 again; in photovoltaic junction box 1 and miniature inverter 2 junctions a sealing rubber ring is installed, can be prevented effectively that like this steam from entering photovoltaic junction box 1.
In Fig. 3, opening two U-shaped holes on the correspondence position of self-clinching stud 5 on the aluminium alloy support bar 3 with on the inverter, inverter self-clinching stud 5 just in time can be packed in the U-shaped hole, be fixed with screw then, aluminium alloy support bar 3 can largely be shared the weight of miniature inverter like this.And such aluminium alloy support bar 3 designs make miniature inverter bottom leave 5 to 6 mm distance with backboard 6, and the heat that miniature like this inverter 2 work are sent just can not influence very much the temperature of assembly backboard.
