Cummins Onan Generator - QG 2800i Onboard RV Generator w/ Inverter - 2,800 Watts - Gasoline - CARB Compliant A074X611

Power your RV life the modern way with the Onan QG 2800i Onboard RV Generator. Whether you're replacing an aging unit or adding onboard power for the first time, this inverter-based generator delivers clean, dependable electricity for the essentials that make life on the road comfortable, with enough output to run a 13,500 BTU high-efficiency air conditioner along with your fridge, outlets, and small appliances.

Designed to Replace Earlier Onan 2800i Models

If you're swapping in the QG 2800i for an older Onan 2800i, the overall layout will look familiar. Intake, exhaust, and drain locations generally align with earlier models, so major bay modifications usually aren't required. You'll still need to reconnect the fuel line, electrical wiring, and exhaust components, and minor adjustments may be needed depending on your RV's setup. As with most onboard generators, working with an experienced installer is the easiest path to a clean, correct install the first time.

Reliable Power, Every Time You Hit the Button

After a long day on the road or when the weather turns wet, nobody wants to wrestle with a generator. One-touch start, automatic choke, and remote switching capability make powering up effortless, rain or shine. Just press the button and relax. Built-in shutoffs automatically handle low oil, overloads, and engine quirks, so you can settle in for the night with the fridge cold, the CPAP running, and no worries about unexpected shutdowns.

Inverter Technology for Modern RV Living

The QG 2800i pairs inverter-based electrical output with a Permanent Magnet Alternator to deliver stable, high-quality power, ideal for sensitive electronics like induction cooktops, laptops, and CPAPs. Consistent voltage protects your gear from surges and fluctuations, so there are no flickering lights or unexpected voltage dips. If your rig runs an inverter/charger and lithium battery bank, the steady AC output supports reliable charging without nuisance faults or power rejection. And because the EFI system automatically adjusts fueling based on load and conditions, performance stays consistent at higher elevations and in extreme heat.

Quiet Enough to Pass the Neighbor Test

Sound-dampening technology and an enclosed muffler help keep things peaceful at the campsite. You won't have to raise your voice for campfire stories, cut conversations short, or lose sleep to engine noise. The QG 2800i meets National Park Service noise guidelines (60 dB @ 50 ft), so you can take in the Great Smoky Mountains, the Grand Canyon, or your favorite national forest without worrying about generator complaints.

USDA Spark Arrestor & 50-State Certified

The included USDA Forest Service approved spark arrestor muffler makes the QG 2800i safe for national forests and campgrounds with no modifications needed for compliance. It's also CARB-certified, EPA Tier 3 compliant, and National Park approved, making it legal to operate anywhere you travel in the U.S. and Canada.

Simple Upkeep for the Real World

From routine oil changes to air filter replacements, regular maintenance is straightforward. You don't need to be a mechanic. Basic tools and standard service intervals are usually all it takes to keep things running reliably for years. Built-in self-diagnostic capability also makes troubleshooting quicker and easier, so you spend less time chasing down issues and more time enjoying your RV.

A Long-Term Upgrade to How You Travel

For many RV and van owners, an onboard generator quickly becomes something they rely on every trip. It lets you manage heat, run appliances, and stay comfortable without planning every trip around hookups. Whether you're replacing an older unit, stepping up to more power, or adding an onboard generator for the first time, the QG 2800i frees you up to travel without being tied to weather, location, or campground availability — an upgrade that keeps paying off year after year.
