RVMP Flex Power 5500e | 5500 Watt EFI Dual-Fuel Installed RV Generator - 4L1-RV551-EFI

The next generation of RV generators. The RVMP Flex Power® 5500e RV Generator is designed for permanent installation.  It runs on a flexible and reliable single-cylinder 224cc OHV air-cooled engine with a digital governor. 

Features
  • Electronic Fuel Injected for increased efficiency and clean power
  • Dual Fuel - 2 types applicable in one unit: Gasoline or Propane.
  • Hassle-free electric start system with remote start lets you start the generator from inside the coach.
  • Designed for reliable service with all total low harmonic distortion for use with sensitive electronics.
  • Emergency backup recoil start gives you further peace of mind when you are using the Flex Power 5500e – No other generator has this capability
  • Multi-pole PM brushless alternator incorporates a digital voltage regulator. The total harmonic distortion is only 3%, which makes it safer to power all types of electronic devices.
  • Offers stepped-up power-on-demand, eliminating issues of overload. The motor slows down when you reduce load and will speed up when you resume a higher load. High performance, low cost, quiet operations, and fuel efficiency make this RV generator the best in its class by every measure.
  • Compared to the competition: The Flex Power® 5500e is lighter, more fuel efficient, lower in harmonic distortion, quieter, has a higher base load, and has many more features.
  • 100% replacement for Onan installed generators - Fits in the same space as Onan and other competitors.
  • Your safety is our concern, the Flex Power® 5500e includes many safety features that go above and beyond industry standards. Including a digital valve controller that offers auto shut-off for fire prevention.
  • Exceeds U.S. Forest Services (USFS), CSA, RVIA, and EPA emission requirements.
  • Original equipment for Forest River, Brinkley, and Thor Industry.
What our Experts Think
  • High-Power RV Upgrade: Delivers 5500W EFI dual-fuel output, making it strong enough to run RV air conditioners, kitchen appliances, and full off-grid setups.
  • Dual-Fuel Flexibility: Supports gasoline and propane operation, giving RV owners better fuel availability, cleaner running options, and extended travel independence.
  • EFI Efficiency Advantage: Electronic Fuel Injection improves fuel economy, smoother operation, and reliable starts in different weather conditions with reduced maintenance needs.
  • Clean Inverter Power: Produces low harmonic distortion (~3%), making it safe for sensitive electronics like laptops, TVs, chargers, and modern RV systems.
  • Quiet & RV-Friendly Design: Engineered for low-noise operation (~around 50+ dB range), ideal for campgrounds, national parks, and long stays.
  • Safety-Focused Engineering: Includes auto shutoff protection, heat sensors, and advanced fuel control systems designed to reduce fire and overload risks.
  • Best For: RV owners who want a premium installed generator with maximum power output, dual-fuel flexibility, EFI reliability, and clean inverter-grade electricity for full off-grid living.

Maintenance Tips
  • Run the generator monthly (20–30 minutes) to keep the EFI system and engine components properly lubricated.
  • Check engine oil before every use and follow scheduled oil changes for reliable 5500W performance.
  • Inspect dual-fuel (propane & gasoline) lines regularly for leaks, cracks, or loose fittings.
  • Keep air filter, cooling vents, and exhaust system clean to prevent overheating and power loss.
  • Use fresh fuel and fuel stabilizer during storage to protect the EFI fuel system and injector.
  • Monitor operating hours and perform timely service on spark plug, filters, and general tune-ups.
  • Ensure mounting hardware and electrical connections remain tight due to RV vibration.
  • Test remote start and safety shutdown features periodically for safe and dependable operation.
