PROBLEM TO BE SOLVED: To provide a small-sized DC power supply monitoring system capable of achieving cost reduction promotion of size and cost reductions by solving the following problem: In the DC power supply monitoring system for photovoltaic power generation, incorporation of a battery for reducing the number of power supply wires has interrupted promotion of size and cost reductions.SOLUTION: The DC power supply monitoring system includes: a first plus connection terminal and a first minus connection terminal connected with a plus-side power supply terminal and a minus-side power supply terminal of a first DC power supply device and a second plus connection terminal connected with a minus-side power supply terminal of a second DC power supply device, and is powered through the first plus connection terminal and the first minus connection terminal connected with the first DC power supply device.SELECTED DRAWING: Figure 1 |
