Embodiment

[0047] Such as figure 1 As shown, it is a schematic structural diagram of a photovoltaic inverter power generation system according to an embodiment of the present invention,

[0048] A photovoltaic power generation system, comprising: a PV panel 1, a photovoltaic inverter 2,

[0049] PV panel 1 is used to convert the received solar energy into direct current;

[0050] The photovoltaic inverter 2 is used to convert the direct current generated by the PV panel into alternating current, and the alternating current is supplied to the grid or the load 4 through the LC filter device 3; the PV panel 1 has 2-way (PV1, PV2) outputs, and the inverter 2 has 2-way MPPT enter.

[0051] Such as figure 2 As shown, it is a principle diagram for judging when the voltage of the 2-way PV panel of the embodiment of the present invention is less than 10V,

[0052] When the voltage of the two PV panels is less than 10V, the goal of distinguishing the voltage difference between the two PV pane...

Abstract

The invention discloses an automatic identification method for input types of a multichannel MPPT inverter. The automatic identification method is used for solving the problem that an existing dual-channel (multichannel) MPPT inverter product is incapable of automatically identifying the types of input PV panel groups; meanwhile, during PV panel examination, only one PV input panel group needs to be switched off rather than all the input PV panel groups, and therefore, the operation efficiency of the system is improved.

Description

technical field [0001] The invention relates to a photovoltaic inverter, in particular to an automatic discrimination method for multi-channel MPPT input types on the direct current side of the photovoltaic inverter. Background technique [0002] In recent years, the scale of development and utilization of renewable energy has gradually increased, and many countries and regions have introduced renewable energy systems such as photovoltaic power generation and wind power generation. With the in-depth development and widespread promotion of photovoltaic power generation technology, the requirements for the flexibility and diversity of input photovoltaic cell array (PV) configurations of photovoltaic inverters are also getting higher and higher. [0003] Photovoltaic cell array refers to the whole battery with a certain voltage and power level, which is composed of standard units of photovoltaic panels combined in series and parallel, that is, PV panels. [0004] Most of the e...
