Title:
POWER CONDITIONER
Document Type and Number:
Japanese Patent JP2016086493
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a photovoltaic power generation system having increased efficiency by accommodating high DC voltage input without involving cost increase, as high DC voltage input into a power conditioner requires change of a switch for use on solar panel side to one with a high rated voltage, which incurs cost increase.SOLUTION: The power conditioner includes: a power converter for converting DC power from a solar cell module into AC power; and a DC switch for connecting the solar cell module with the power converter. Wiring of the switch for DC is made in the order of PNP.SELECTED DRAWING: Figure 8
