Document Type and Number:
WIPO Patent Application WO/2017/175535
Kind Code:
A1
Abstract:
According to the present invention, a solar cell string (11) has a plurality of solar cell units (20) connected in series. In each of the solar cell units (20), a solar cell module (21) is connected to/separated from a cable run (23) by an optimizer (22). A ground fault detection device (34) instructs the optimizer (22) to perform switching to the connection or the separation, and, after the instruction, determines the presence/absence of a ground fault in the solar cell string (11).
