It connects, wherein N=1,3,5；Wherein the connection structure of m-th photovoltaic group string is the anode connection second of first photovoltaic module
The cathode of photovoltaic module, the cathode of anode the P+2 photovoltaic module of connection of the P photovoltaic module, wherein P=2,4,6,8,
10,12,14,16,18,20, the cathode of the Q photovoltaic module connects the anode of the Q+1 photovoltaic module, wherein Q=1,3,5,
7,9,11,13,15,17,19, the cathode of the 21st photovoltaic module and the anode of the 22nd photovoltaic module are connected to terminal box；
The G photovoltaic group string and the N+1 photovoltaic group string are respectively connected to a terminal box, and each terminal box is sequentially connected with and connects inversion
Device.
The plug-in type lead photovoltaic component terminal box and solar photovoltaic assembly string of the utility model have below beneficial to effect
Fruit: in normal operating conditions, the inversion efficiency of entire battery array is unaffected.When battery array is because irradiating uneven, portion
When the reasons such as point blocking keeps part photovoltaic group string working condition bad, the degree of susceptibility of all groups of strings and whole system is down to
It is minimum, it is ensured that inversion efficiency.
Detailed description of the invention
Fig. 1 is that a kind of novel photovoltaic group of the utility model concatenates the structural schematic diagram of cable architecture.
Specific embodiment
As shown in Figure 1, the present embodiment proposes a kind of novel photovoltaic group concatenation cable architecture, including six photovoltaic group strings, each
Photovoltaic group string includes 22 photovoltaic modulies；Wherein n-th photovoltaic group string is sequentially connected with by 22 photovoltaic modulies, wherein N=
1,3,5；Wherein the connection structure of the N+1 photovoltaic group string is anode second photovoltaic module of connection of first photovoltaic module
Cathode, the cathode of anode the P+2 photovoltaic module of connection of the P photovoltaic module, wherein P=2,4,6,8,10,12,14,
16,18,20, the cathode of the Q photovoltaic module connects the anode of the Q+1 photovoltaic module, wherein Q=1,3,5,7,9,11,13,
15,17,19, the cathode of the 21st photovoltaic module and the anode of the 22nd photovoltaic module are connected to terminal box；N-th photovoltaic group
String is respectively connected to a terminal box with the N+1 photovoltaic group string, and each terminal box is sequentially connected with and connects inverter.
A kind of novel photovoltaic group of above structure concatenates cable architecture and has the advantages that in normal operating conditions, entirely
The inversion efficiency of battery array is unaffected.When battery array makes part photovoltaic group because irradiating the reasons such as uneven, partial occlusion
When working condition of going here and there is bad, the degree of susceptibility of all groups of strings and whole system is minimized, it is ensured that inversion efficiency.
It should be appreciated that those skilled in the art according to the present utility model can conceive without creative work
Make many modifications and variations.Therefore, all technician in the art are according to the design of the utility model in the prior art
On the basis of by the available technical solution of logical analysis, reasoning, or a limited experiment, all should be by claims institute
In determining protection scope.
