A055E865 3.6KYFA-26120 CUMMINS/ONAN RV QG 3600 LP-3600 WATT 120V SGL PHASE 60HZ FIXED MOUNT LP GENERATOR

Power your RV's appliances and air conditioning from your existing propane supply with the Cummins Onan RV QG 3600 LP Onboard Generator (Part #3.6KYFA-26120 / A055E865). This 3,600-watt liquid propane-powered, fixed-mount generator is part of Onan's quiet gasoline (QG) series — engineered for low noise, low vibration, and reliable onboard power that integrates cleanly with the LP system your RV already has.

Why LP Power Makes Sense in an RV

Running an onboard generator off liquid propane means you can use the same fuel supply that powers your furnace, water heater, stove, and refrigerator. No separate gasoline tank to fill, no fuel stabilizer concerns over winter storage, and no carrying fuel cans. If your RV is already set up for LP, this generator slots right in.

3,600W of Onboard Power

The QG 3600 LP delivers 3,600W of AC running power at 120V, with 30 amps of maximum AC current — enough to run one air conditioner with power to spare, plus your other RV electrical needs. Ideal for mid-size and smaller RVs where you want reliable onboard AC capability.

Quietest in Its Class

The QG 3600 LP is the quietest in its class, with exceptionally low vibration levels — a meaningful quality-of-life upgrade over older noisy generators. Combined with the integrated design with enclosed muffler, you get a generator that's significantly more pleasant to live with at the campsite.

Digital Voltage Regulation

The QG 3600 LP includes digital voltage regulation that delivers clean, stable AC output even as your appliance loads change throughout the day. AC cycling on and off, microwave starting up, refrigerator kicking in — the generator handles those load shifts cleanly rather than letting them affect your sensitive electronics.

Smart Features for Reliable Operation

The QG 3600 LP is built with features that make it easier to live with and easier to troubleshoot:

• Self-diagnostic capability simplifies troubleshooting if something goes wrong
• Automatic choke — no manual fiddling for cold starts
• Automatic low oil shutdown protects the engine from damage
• Integrated design with enclosed muffler makes installation simpler

Onboard Fixed-Mount Design

Unlike portable generators, the QG 3600 LP is a non-portable, onboard fixed-mount generator designed for permanent installation in your RV's generator compartment. That means no extension cords, no loading/unloading, and one-button starting from inside the RV.

Prefer Gasoline?

If you'd rather run gasoline than LP, the Cummins Onan QG4000 EVAP gasoline onboard generator is the same QG series platform with 4,000W output — running on gasoline instead of propane.

Built for Long-Term Use

A 304 cc single-cylinder, 4-stroke, OHV (overhead valve), air-cooled engine delivers durable, proven performance. The QG 3600 LP is EPA Tier 3 certified.
