Description

Cost-Effective Dual-Module Rapid Shutdown Protection for Solar PV Systems

The APsystems RSD-D (446101) is an advanced, high-efficiency rapid shutdown device (RSD) engineered to meet NEC 2017, 2020, and 2023 (690.12) requirements for module-level rapid shutdown. Designed to manage two PV modules simultaneously, the RSD-D significantly reduces hardware costs and installation labor compared to single-unit alternatives.

Powered by SunSpec-compliant Power Line Communication (PLC), the RSD-D seamlessly integrates with string inverters and certified transmitters, ensuring optimal rooftop safety for installers and emergency first responders.

Key Features & Benefits

Dual-Module Control: Connects directly to two separate PV modules, cutting the required number of shutdown hardware units in half and lowering overall system balance-of-system (BOS) costs.
SunSpec PLC Communication: Utilizes standard SunSpec Power Line Communication (PLC) over existing DC lines, eliminating the need for dedicated communication wiring or wireless setup.
NEC 690.12 Compliance: Accurately attenuates array voltage below safe limits within seconds of system shutdown, ensuring full compliance with national electrical safety codes.
Automatic Safety Shutdown: Automatically drops module output voltage when utility AC power is interrupted or when the PLC transmitter signal stops.
Rugged Weatherproof Build: Features an IP68 / NEMA 4X enclosure designed to withstand extreme rooftop weather, UV radiation, and severe temperature fluctuations.
