Product Description Product DescriptionPhotovoltaic (PV) rapid shutdown is a safety feature that is required for PV systems installed on or near buildings in the United States. Rapid shutdown is designed to quickly reduce the voltage and current in a PV system to a safe level in the event of an emergency, such as a fire or an earthquake. This can help to prevent electrical shocks and fires, and make it easier for emergency responders to safely access the PV system.There are several ways to implement rapid shutdown in a PV system. One common method is to use a rapid shutdown controller, which is a device that is installed in the PV system and connected to a switch or other control mechanism. When the switch is activated, the rapid shutdown controller cuts off power to the PV panels and reduces the voltage and current to a safe level.Other methods of implementing rapid shutdown include using specialized PV cables that are designed to rapidly reduce the voltage and current in the event of an emergency, or installing special rapid shutdown devices at key points in the PV system.Regardless of the method used, it is important to ensure that a PV system is properly designed and installed to meet the requirements for rapid shutdown, as outlined in the National Electric Code (NEC) and local building codes. This can help to ensure the safety of building occupants and emergency responders, and can also help to protect the PV system and its components.
