Therefore, be necessary to provide a kind of improved photovoltaic generation connected system to address the above problem.
Utility model content
The purpose of this utility model is to provide a kind of wiring simple photovoltaic generation connected system.
For realizing above-mentioned utility model object, the utility model provides a kind of photovoltaic generation connected system, it comprise one-level header box, some photovoltaic module arrays and be connected in one-level header box and photovoltaic module array between some secondary header boxs, described photovoltaic module array is connected to described one-level header box by described secondary header box, and the distance between described photovoltaic module array and secondary header box is less than the distance between this secondary header box and one-level header box.
As further improvement of the utility model, between described secondary header box and photovoltaic module array, be also provided with LED monitoring device, this LED monitoring device is provided with for showing electric current and the whether normal LED light of voltage ratio in the photovoltaic module array of place.
As further improvement of the utility model, between described one-level header box, secondary header box and photovoltaic module array, adopt cable to connect, and the cable number of connection between described secondary header box and one-level header box is less than the cable number of connection between described photovoltaic module array and secondary header box.
As further improvement of the utility model, described photovoltaic generation connected system include 16 groups described in photovoltaic module array, and every 4 groups of photovoltaic module arrays are parallel with one another is connected to a secondary header box.
As further improvement of the utility model, described in each, secondary header box comprises four input cable connecting pieces and an output cable connecting piece; Described input cable connecting piece is connected with four groups of photovoltaic module arrays by cable, and described output cable connecting piece is connected with described one-level header box by cable.
As further improvement of the utility model, described secondary header box has non-metal shell and is arranged on the metal base plate in non-metal shell, and described input cable connecting piece and output cable connecting piece are arranged on described metal base plate.
The beneficial effects of the utility model are: the utility model by arranging some secondary header boxs between one-level header box and photovoltaic array, after being confluxed via secondary header box, photovoltaic module array accesses again one-level header box, not only can save cable thus, and because one-level header box place only has the several wire cable access that connects secondary header box, thereby make wiring more simple.
