That is why solar rapid shutdown and DC isolation need to be treated as separate design functions. Quick answer: A DC isolator opens a circuit at its installation point. A rapid shutdown system controls designated PV conductors after a shutdown signal, using an approved equipment arrangement. An ordinary DC isolator alone does not establish that a rooftop system meets rapid shutdown requirements. This guide is for installers, distributors and project buyers comparing protection equipment. Electrical work and shutdown verification must be performed by qualified personnel using the applicable equipment instructions. What does a DC isolator do?
