xAPsmart RSD-D Dual-Module Rapid Shutdown Device
The APsmart RSD-D is a specialized safety solution that provides rapid shutdown for two solar modules simultaneously. Fully compliant with SunSpec interoperability protocols, this device uses Power Line Communication (PLC) to integrate seamlessly with compatible SunSpec-certified inverters. It is an ideal choice for installers looking to satisfy NEC 2017 & 2020 690.12 requirements while minimizing the total number of components on the roof.
Cost-Effective Dual-Module Safety
- Dual-Module Control: Monitors and shuts down two PV modules with a single unit, reducing labor and hardware costs.
- SunSpec Certified: Communicates via PLC for broad compatibility with SunSpec-compliant inverters and transmitters.
- High Power Capacity: Supports two modules with an input power of up to 800W per channel (1600W total).
