Built for modern commercial solar installations, the ProJoy PEFS-EL50 delivers a practical and scalable rapid shutdown solution for rooftop PV systems in Canada. Designed to support projects where inverters are installed away from the array, it enhances safety by automatically de-energizing DC circuits when AC power is interrupted, while integrating easily with existing building safety infrastructure. Suitable for a wide range of system voltages, it provides a streamlined and cost-efficient alternative to module-level shutdown devices, helping simplify design, reduce hardware requirements, and maintain dependable system performance. cETLus listes for Canada & USA.
