ELECTRICAL SAFETY SHUTOFF SYSTEM AND DEVICES FOR PHOTOVOLTAIC MODULES

摘要

An electrical safety shutoff system and devices for disabling electrical power output from individual photovoltaic modules in a photovoltaic array, including one or more shutoff circuits, each of which can disable electrical power output from an associated module; and at least one enable signal generator that transmits a signal to the shutoff circuits to enable power output; wherein module power output is disabled in the absence of the enable signal.
