Title:
CONNECTION BOX AND PHOTOVOLTAIC POWER GENERATION SYSTEM
Document Type and Number:
Japanese Patent JP2013191635
Kind Code:
A
Abstract:

To achieve a connection box with which calorific values of backflow prevention diodes when solar cell strings are connected in a reversed polarity can be reduced with a simple configuration.

A connection box connects a plurality of solar cell strings in parallel to a power conditioner. The connection box includes: a plurality of pairs of input terminals configured to connect the plurality of solar cell strings thereto; a pair of output terminals configured to connect the power conditioner thereto; a plurality of first backflow prevention diodes connected between the plurality of pairs of input terminals and the pair of output terminals; and a plurality of second backflow prevention diodes connected between the plurality of pairs of input terminals so as to respectively form closed loops when the solar cell strings are connected in a reversed polarity.
