Pole pipe quantity is 2 ~ 4, and the bypass diode quantity of two line terminal boxes is 1 ~ 2, and each bypass diode is connected in parallel one
Solar cell string.
Described four line terminal boxes and two line terminal boxes are installed on back plate surface, its position be located at backboard top or under
Portion.
The present invention sets multiple different types of terminal boxes by module backside, is connected using terminal box lead-out terminal
Connected mode of the various combinations to control between solar cell string, by selecting different connected modes, changes component reality
Output electric property energy parameter.When photovoltaic system end needs DC input voitage higher, the positive pole of different terminal boxes is exported
Terminal and negative output terminals are connected two-by-two, so as to by the series connection of multiple solar cell strings, realize the high output voltage of component；When
When photovoltaic system end needs direct current input current higher, by the positive output terminals and negative output terminals of different terminal boxes point
It is not connected in parallel, so as to by multiple solar cell connection in series-parallel, realize the High Output Current of component.Therefore this many terminal boxes
Set-up mode causes the regulation of the unit for electrical property parameters of component more flexibly and conveniently, is greatly enlarged the range of application of component.
