PHOTOVOLTAIC GENERATION SYSTEM, POWER CONVERSION DEVICE, AND COLLECTOR BOX

摘要

A photovoltaic generation system includes: a solar cell array that includes a plurality of solar cell modules; a collector portion that collects power from the solar cell array; a power control portion that is connected to the collector portion and includes a power conversion portion which converts first power from the solar cell array into second power; a first electric wiring that connects the collector portion and the power control portion to each other; a first connection terminal that is supplied with the first power from the solar cell array; and a first switch portion that shuts off output from the solar cell array for the power conversion portion; wherein an alternative power control portion is connectable to the first connection terminal.
