Problems solved by technology
There are many problems in the networking and operation of the series-parallel mode: how to find out the failed photovoltaic cell modules in time? How to prevent internal circulation between multiple square arrays connected in parallel? How can we effectively prevent damage caused by outdoor lightning strikes? The solution to the above problems requires the development of a scientific and effective photovoltaic confluence system
The disadvantage of this control method is that all photovoltaic units in the photovoltaic array 11 can only apply the same control strategy, and the flexibility of the control method is not high.
Moreover, once the control panel 13 that performs centralized control fails, the photovoltaic units in the photovoltaic array 11 will not work.

Embodiment Construction
[0014] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.
[0015] The embodiment of the present invention provides a technical solution of a photovoltaic confluence system with a charging function. see figure 2 , in the photovoltaic confluence system with charging function provided by the embodiment of the present invention, the photovoltaic units on each branch are directly connected to the corresponding control board 32 . That is to say, the setting position of the control board 32 is changed from after the original confluence to before the confluence. In this way, i...

The embodiment of the invention discloses a photovoltaic convergence system with a charging function. The photovoltaic convergence system comprises at least two control boards and buses, wherein the two control boards are respectively connected with a photovoltaic unit and the bus, and are used for performing MPPT (maximum power point tracking) control on the output current of the photovoltaic unit, and outputting the output current controlled by the MPPT to the bus, wherein each photovoltaic unit is arranged on a branch line of the corresponding control board; the buses are respectively connected with the at least two control boards and loads, and are used for converging the output current of all control boards, and utilizing the converged current to drive the loads. The photovoltaic convergence system with the charging function is used for conveniently and independently controlling the different photovoltaic units.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of photovoltaic power supply, and in particular to a photovoltaic confluence system with a charging function. Background technique [0002] Solar photovoltaic (Photovoltaic, PV) power generation is a new technology that converts solar energy into electrical energy by using the photovoltaic effect generated on the semiconductor surface of solar cells. Since solar energy is a low-density planar energy source, it is necessary to combine solar photovoltaic arrays of a certain scale in series and parallel to achieve the required voltage and current values in order to achieve the best power generation efficiency. There are many problems in the networking and operation of the series-parallel mode: how to find out the failed photovoltaic cell modules in time? How to prevent internal circulation between multiple square arrays connected in parallel? How can we effectively prevent damage cause...
