SOLAR POWER GENERATION NETWORK SHUT-OFF UNIT AND SOLAR POWER GENERATION NETWORK SHUT-OFF SYSTEM COMPRISING SAME

摘要

This solar power generation network shut-off unit (1) comprises a first breaker (20) and second breakers (30). The first breaker (20) is provided in a power line (14) that connects a plurality of solar power generation modules (11) and a power conditioner (12) in series, and when an emergency shut-off button (13) is operated, the supply of power from the solar power generation modules (11) through the power line (14) is shut off, and an emergency shut-off signal is transmitted. The second breakers (30) are each provided to each of the plurality of solar power generation modules (11), and when the emergency shut-off signal is received from the first breaker (20), the second breakers (30) shut off the supply of power from the plurality of solar power generation modules (11) through the power line (14).
