The Cummins RS13A delivers 13 kilowatts of reliable backup power for your home with industry-leading quiet operation at just 65 dB(A). This air-cooled standby generator features the QSJ999G V-twin overhead valve engine, designed to automatically power your home during outages when paired with an optional transfer switch.
Built with an aluminum exterior enclosure and galvanized steel interior, the RS13A withstands wind loads up to 180 mph per ASCE7-10 standards. The generator operates in temperatures from 0°F to 122°F out of the box, with extreme cold weather kits available for -40°F environments. NFPA 37 compliance allows installation just 18 inches from your building.
Monitor and control your generator from any computer, smartphone, or tablet. Built-in remote monitoring lets you check status, adjust exercise modes, and manually run the generator from anywhere. The under-hood display provides quick access to system information on-site.
The RS13A starts and runs a 5-ton air conditioning unit even under full pre-load conditions, with 26 kVA motor starting capacity at 30% voltage dip. Intelligent Load Management monitors up to 4 loads continuously, restoring power based on available generator capacity for maximum efficiency.
Set exercise schedules by time, date, and frequency to match your needs. Cummins patented "crank only" mode cranks the engine and runs diagnostics without starting, reducing wear, fuel costs, and noise from an already quiet generator.
Field-selectable for natural gas or propane vapor operation (factory set to natural gas). Fuel supply pressure requirements: NG 3.5-12.0 in H2O, LP 6.0-12.0 in H2O. The system includes a 4-amp battery charger and requires a Group 51R 450 CCA battery.
