Abstract

The present disclosure provides a photovoltaic (PV) disconnect device used in an electrical system. The PV disconnect device includes a relay component electrically coupled to a feed circuit of a backup PV power generation system and a connector port electrically coupled to an energy control system. The PV disconnect device includes a sensor circuit to measure at least one of a voltage, a current, and a current frequency of the feed circuit of the backup PV power generation system. The PV disconnect device includes a controller operatively coupled to the relay component, the sensor circuit, and the connector port. The controller receives and processes the voltage, the current, and the current frequency measurements. The controller selectively actuates the relay component based on the processed voltage, current, and current frequency measurements.
