Rapid Shutdown isn’t just for solar panels—it also applies to battery backup systems. During a grid outage or emergency, battery storage systems continue to provide power to the home. However, if a shutdown is needed, these batteries must automatically stop delivering electricity to prevent electrical hazards. Why is this important?
Even if the solar panels stop producing power, batteries store energy and can continue feeding electricity into the home’s circuits. Without Rapid Shutdown, this could create a shock risk for firefighters or maintenance personnel. How does it work?
Solar rapid shutdown refers to the ability, mandated by regulation, to easily shut down a solar panel system in case of an emergency. Rapid shutdown regulations were first implemented in 2014 as a safety precaution by the National Electrical Code (NEC), offering a fast and effective way of cutting off the electricity running through the system.
To prevent this, the National Electrical Code (NEC) mandates the Rapid Shutdown feature to ensure a safer working environment. Traditional solar PV systems are DC-based, meaning they produce direct current (DC) electricity, which remains live as long as sunlight is available.
Our photovoltaic systems and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
