Cummins 20kW Quiet Connect Home Standby Generator with 200A Service Disconnect
The Cummins RS20AC/RS20ACE delivers 20 kilowatts of reliable backup power for whole-house protection during grid outages. This natural gas or propane-powered standby generator includes a 200-amp automatic transfer switch for seamless power transitions when utility power fails.
Whole House Power Capacity
With 20kW output and 40 kVA motor starting capability, the RS20AC powers central air conditioning, refrigeration, heating systems, and essential appliances simultaneously. The single 100A UL-certified circuit breaker protects your electrical system while the generator maintains ±1.25% voltage regulation from no load to full load.
Intelligent Load Management System
The optional intelligent load management controls up to 4 separate loads, continuously monitoring power requirements for each circuit. This system automatically prioritizes and restores loads based on available generator capacity, maximizing power distribution efficiency across your home.
Remote Monitoring and Control
Built-in remote monitoring allows control via computer, tablet, or smartphone. Monitor generator status, adjust exercise schedules, and manually start the unit from anywhere. The Cloud Connect app provides real-time alerts and diagnostics for complete peace of mind.
Quiet Operation and Compact Installation
NFPA 37 certification permits installation just 18 inches from your building. The aluminum exterior with galvanized steel interior is engineered to withstand 180 mph wind loads per ASCE7-10 standards. Operation remains whisper-quiet, minimizing disturbance to your household and neighbors.
All-Weather Performance
The RS20AC operates in temperatures from 122°F down to 0°F out of the box. The RS20ACE extreme weather model extends cold weather performance to -40°F without additional kits. The QSJ999G V-twin air-cooled engine with 999cc displacement delivers consistent power in harsh conditions.
Flexible Exercise Modes
Customizable exercise schedules maintain generator readiness on your preferred time, date, and frequency. The patented crank-only exercise mode runs diagnostics without starting the engine, reducing fuel consumption, wear, and noise during routine maintenance cycles.
