Cummins

Cummins has over a century of experience in power generation and is trusted worldwide for residential, commercial, industrial, and RV applications. Their generators are designed for long-term reliability, high performance, and easy operation. Many Cummins models also include advanced features such as electronic fuel injection (EFI), inverter technology, remote start, and multiple fuel options. These innovations make Cummins a popular choice for dependable backup power.

Cummins Onan portable generators are designed to be moved where power is needed, making them ideal for home backup, RVs, camping, and job sites. Quiet Connect™ generators are permanently installed standby systems that automatically restore power when utility service is interrupted. Portable models offer flexibility, while Quiet Connect systems provide automatic whole-home backup.

Electronic Fuel Injection (EFI) replaces a traditional carburetor with an electronically controlled fuel delivery system. EFI helps improve cold-weather starting, fuel efficiency, throttle response, and overall engine performance. It also reduces routine carburetor maintenance, making it especially useful for generators that may sit unused between emergencies.

The P4500i is a gasoline inverter generator designed for portable power and sensitive electronics. The P5000iDF EFI adds dual fuel capability and electronic fuel injection for greater fuel flexibility and easier starting. The P11000iTF delivers significantly more power and can operate on gasoline, propane, or natural gas, making it one of Cummins' most versatile portable generators for home backup.

For RV owners, the Cummins Onan P2500i, P4500i, and QG 7000i DF are among the most popular options. Smaller inverter generators are ideal for travel trailers and basic RV power, while larger models can support RV air conditioners and additional appliances. The best choice depends on your RV's electrical requirements and whether you need a permanently installed or portable solution.

Yes. Cummins offers compatible manual and automatic transfer switches that allow generators to safely supply power to selected household circuits. Using a transfer switch helps simplify backup power while preventing dangerous backfeeding into utility lines. Selecting the proper transfer switch depends on your generator model and home's electrical system.

Cummins offers a wide range of genuine accessories, including maintenance kits, running covers, generator covers, transfer switches, extension cords, parallel kits, replacement batteries, high-altitude kits, remote display panels, and cold-weather accessories. These products are designed specifically for Cummins equipment to help maintain performance and simplify installation and maintenance.

Yes. Certain Cummins inverter generators, including the P2500i, support parallel operation using an approved parallel kit. Connecting two compatible generators increases available power while maintaining the portability of smaller units. This is a popular option for RV owners and users who occasionally need additional output without purchasing a larger generator.

Yes. Cummins offers portable, RV, and standby generators designed for dependable operation during extended outages. Models with dual fuel or tri-fuel capability provide additional flexibility when fuel availability becomes limited after severe weather. Combined with routine maintenance and proper fuel storage, a Cummins generator can provide reliable backup power for years.

The right generator depends on your application, power requirements, and preferred fuel type. Portable inverter generators are ideal for camping, RVs, and powering essential appliances, while larger tri-fuel generators are better suited for home backup. Quiet Connect™ standby generators are the best option for homeowners who want automatic backup power.
