APsmart Rapid Shutdown Solutions

APSmart logo

APsmart is the brand brought to us by designers at APsystems.  The solutions offer state-of-the-art PV module level rapid shutdown devices that work seamlessly with any new or existing string or central inverter system.  The RSD-S-PLC meets SunSpec requirements, maintaining normal function of the PV system by continually receiving a heartbeat signal from the APsmart Transmitter.  When no signal is present, the unit executes rapid system shutdown.  This solution meets U.S. NEC 2017 & 2020 690.12 Rapid Shutdown requirements. By maximizing APsystems’ proven expertise in module-level power electronics, APsmart solutions are powered by ASIC with internal IP and integrated with TI chips at the system-level application.

APSmart pv module level rapid shutdown at a Glance
