Since NEC 2014, rooftop solar systems have had a new requirement: Rapid Shutdown. The goal is simple – protect firefighters and first responders by de-energizing PV conductors quickly during an emergency.

The problem: Even when a grid-tied inverter shuts down during a power outage, the PV source circuits (the wires from your array to the inverter) stay live. That's a hazard for anyone chopping through a roof or wall.

The solution: Article 690.12 requires that conductors more than 5 feet inside a building or more than 10 feet from an array be limited to 30V and 240VA within 10 seconds of shutdown.

That's where we come in. We carry MidNite Solar's line of Rapid Shutdown equipment, including components to disconnect battery-based systems, inverters, and AC generators.
