Timely tech from ZERUN: the rapid shutdown device

Given the conditions that led to the recent fire season out west, the use of full solar system rapid shutdown devices (RSD) by contractors when they install rooftop solar systems is becoming increasingly important. While microinverters satisfy rapid shutdown requirements, there are vendors that offer stand-alone RSD options. One company that offers an inverter-agnostic stand-alone device is ZERUN. It is a small, compact device that can be installed on a module’s backsheet with adhesive or mounted on the module frame with a metal bracket.
