In order to achieve the above object, the utility model adopts following technical scheme:
A kind of solar panel array cascaded structure, described cascaded structure is connected with controller by the panel array group and forms, described controller has one or more input ports, each input port of described controller is connected with negative pole with the positive pole of a Battery pack plate array group, described every Battery pack plate array group is composed in series by two panel arrays, the positive pole of one of them panel array is connected with the positive pole of controller input, the negative pole of another one panel array is connected with the negative pole of controller input, the tie point place ground connection of two series-connected cell plate arrays.
The number of cell panel is more than or equal to 1 in described each panel array, and the number of institute's series-connected cell plate equates or unequal in two panel arrays of connecting in every Battery pack plate array group.
Identical or not identical with the position of the number of cell panel series connection in each panel array group that each input port of controller is connected and earth point.
Because controller has one or more input ports, therefore the present invention includes one or more groups panel array group that is connected with the controller input, by two panel arrays are connected, the positive pole of one of them panel array is connected with the positive pole of controller input, the negative pole of another one panel array is connected with the negative pole of controller input, realization system positive-negative power supply, can realize on the constant basis of original cell panel voltage withstand class in this way the High Level DC Voltage output of system's twice, effective raising system DC side supply power voltage, reduce the power loss of line loss and relevant device, improve system effectiveness.
