Yamaha 5500W/6300W Electric Start Gas Inverter Generator with CO Sensor – 120/240V

Secure reliable backup power for your home, job site, or RV with the Yamaha 5500W/6300W electric start gas inverter generator (model EF6300iSDE). Delivering 6300 peak watts and 5500 rated watts, this unit runs an RV air conditioner, microwave oven, and power tools all at once without breaking a sweat.

The advanced inverter system produces pure sine wave (PWM) power, safe for sensitive electronics, computers, variable-speed tools, and appliances. Electric start with automatic choke means push-button convenience – battery included. Smart Throttle automatically adjusts engine speed to match the load, reducing noise, fuel consumption, and engine wear.

With a 4.5-gallon fuel tank, you get up to 13.3 hours of continuous operation at 1/4 rated load. Noise levels are remarkably low at 58–64 DBA, making it neighborhood-friendly. The built-in CO sensor shuts off the engine if dangerous carbon monoxide levels are detected – essential safety for garages or enclosed spaces. Low oil shutoff protects the engine from damage.

Lightweight at only 200 lbs with twin carrying bars, the generator is easy to transport. Dual voltage 120/240V outlets include two 5-20R standard receptacles, one L5-30R twist lock, and one L14-30R twist lock. This model is legal for sale in all 50 US states (CARB & EPA certified) and fully compliant with European Union standards for customers in Germany, France, Poland, and beyond. Comes with a 3-year limited factory warranty from an authorized Yamaha dealer.
