SMA Rapid Shutdown Initiator ESS-RSD01-RSI50
The SMA ESS-RSD01-RSI50 is an external rapid shutdown initiator (“RSI-US-50”) for SMA Home Energy systems. It provides a convenient, code-compliant way to trigger PV rapid shutdown and/or system shutdown when the inverter and battery are not located at the main service panel—ideal for Sunny Boy Smart Energy (SBSE-US-50) installs.
Key Benefits
Remote RSD Trigger: Adds a clearly located shutdown control when the inverter’s built-in DC switch isn’t easily accessible.
Multi-Inverter Support: Can be wired (via adapter) to control up to three SBSE inverters in one system.
Simplifies NEC 690.12 Compliance: Works within SMA’s SunSpec-certified rapid shutdown solution.
Special Technology
Digital Input Interface: Connects to the SBSE inverter’s rapid-shutdown digital input so either the inverter’s DC load-break switch or the external initiator can trigger shutdown.
SMA Home Energy Ecosystem: Designed for use with Sunny Boy Smart Energy hybrid inverters and SunSpec-compatible RSD components.
Warranty
Manufacturer’s Standard Warranty (SMA).
Best Uses
Remote Equipment Rooms: When the inverter/battery are away from the service panel and an exterior or hallway “red button” is required.
Multi-Inverter Homes: Coordinating shutdown across two or three SBSE units.
