With a 0.6-quart oil capacity (recommended 10W-30 and funnel included) and a low oil shut-off sensor, this inverter operates at 64 dBA from 23 feet, which is a bit louder than normal speech.

The optional Parallel Kit, with included standard 50-amp RV outlet, provides a clip-on connection which allows you to increase output by connecting up to two 2800-watt or higher inverters or digital hybrids.

This inverter is EPA/CARB certified. Buy with confidence – Champion Support and our nationwide network of service centers will back up your purchase with a 3-year limited warranty and FREE lifetime technical support.

CO Shield® technology monitors the accumulation of carbon monoxide (CO), a poisonous gas produced by engine exhaust when the generator is running. If CO Shield® detects unsafe elevated levels of CO gas, it automatically shuts off the engine. CO Shield® is not a substitute for an indoor carbon monoxide alarm or for safe operation. DO NOT allow engine exhaust fumes to enter a confined area through windows, doors, vents or other openings. Generators must ALWAYS be used outdoors, far away from occupied buildings with engine exhaust pointed away from people and buildings. Meets the requirements of ANSI/PGMA G300-2018.
