Cummins RS17A 17kW Home Standby Generator with Automatic Transfer
The Cummins RS17A delivers 17 kilowatts of reliable backup power for whole-home protection during outages. This natural gas or propane standby generator automatically activates when grid power fails, restoring electricity to your home without manual intervention.
Automatic Power Restoration
The RS17A features automatic transfer switch integration that detects power loss and starts the generator within seconds. Remote monitoring capability through the Cloud Connect app allows you to check generator status, modify exercise schedules, and manually run the unit from your smartphone, tablet, or computer.
Intelligent Load Management System
Optional intelligent load management controls up to 4 separate loads, monitoring power requirements for each circuit independently. The system automatically prioritizes and restores loads based on available generator capacity, maximizing the number of appliances you can run simultaneously. Motor starting capacity of 34 kVA handles demanding equipment including 5-ton air conditioning units under full pre-load.
Quiet Operation and Compact Installation
Engineered for residential environments, the RS17A operates at reduced noise levels compared to traditional generators. NFPA 37 certification permits installation just 18 inches from your home. The aluminum exterior with galvanized steel interior is rated to withstand 180 mph wind loads per ASCE7-10 standards.
Dual Fuel Capability
Field-selectable fuel system operates on either natural gas or propane vapor (factory set to natural gas). The QSJ999G engine features a naturally aspirated V-twin design with 999cc displacement, running at 3600 RPM for consistent 60Hz power output with less than 5% total harmonic distortion.
Flexible Exercise Modes
Customizable exercise scheduling lets you set maintenance runs by time, date, and frequency. The patented crank-only exercise mode runs diagnostics without starting the engine, reducing fuel consumption, emissions, and wear while maintaining readiness.
Cold Weather Performance
Standard operating range extends from 122°F down to 0°F. Optional cold weather kits enable operation to -40°F for extreme climates. The 4-amp battery charger maintains starting power year-round.
Technical Specifications
Single-phase 60Hz output with ±1.25% voltage regulation from no load to full load. Isochronous frequency regulation maintains ±1.25% steady-state variation. Single 100A UL-certified circuit breaker included. Direct drive blower cooling system with slip ring heater prevents moisture buildup.
Certifications and Warranty
UL 2200, CSA 22.2, B149.1 certified. EPA emissions compliant. Includes 5-year/2000-hour base warranty with extended coverage available. Synthetic oil, air cleaner, and oil drain extension included.
Features:
Robust Design
The generator is designed to71treme cold weather models can perform down to -40 °F (-40 °C) out of the box. It is tested and certified per the latest EPA, UL, and CSA standards. The generator meets NFPA 37 which allows it to be installed 18 inches from a building. It has powerful motor starting ability and can easily start and run a5-ton A/C¹ under full pre-load.
NOTE: This is not an extreme cold weather model and its operating temperatures are down to O F out of the box.
Intelligent Load Management
The generator can control up to 4 loads and continuously monitors how much
power is required independently for each load. It then controls each load for maximum utilization of generator power by only restoring loads the generator has capacity to run.
Flexible Exercise Modes
Exercise modes can be set for time, date, and frequency that suits the owner. Our patented 'Crank only' exercise mode allows the generator to crank the engine and run diagnostics without starting the engine. This reduces wear and tear on the engine, fuel costs, and further reduces the sound of an already quiet generator.
Remote Monitoring
Remote monitoring is built into every generator. Using a computer, tablet, or smart
phone, an operator can monitor, change exercise modes, and manually run the generator remotely.
