APsmart specializes in advanced PV module rapid shutdown solutions, delivering state-of-the-art safety and compliance for solar power systems. Developed by APsystems, APsmart's offerings include the SunSpec Alliance Certified RSD (Rapid Shutdown Device) System, which maintains constant communication between the RSD and a Transmitter-PLC to monitor voltage and current. In the event of an anomaly or loss of proper voltage, the system instantly initiates a module-level rapid shutdown sequence, ensuring critical safety for emergency responders and compliance with U.S. NEC 2017 & 2020 690.12 Rapid Shutdown requirements.

The company's innovative product line features devices such as the RSD-S-PLC and RSD-D, which are powered by ASIC with internal IP and integrated with TI chips, leveraging proven expertise in module-level power electronics. These solutions are designed for both new and existing string or central inverter systems, offering high reliability, flexibility, and powerful performance with benefits like extended daily module operating periods due to low minimum operation voltage. APsmart also provides the Transmitter-PLC, a crucial component for enabling the rapid shutdown functionality. The technology is engineered to be stable, eliminating unwanted AFCI nuisance tripping while providing robust safety for residential, commercial, and utility-scale solar installations.
