From the manufacturer

Cummins Onan P4500i Inverter Generator EPA Overview The Cummins Onan P4500i includes a telescoping handle and built-in wheels for maximum portability while still delivering up to 4.5kW to power most household appliances and power tools. It includes three starting options: a push start button, a remote key fob, and a backup pull cord. The 3.4 gallon fuel tank delivers up to 18 hours of run time at 25% load while operating at 52dB. This generator can power an RV campsite or provide backup power during an outage. Key Features of the Cummins Onan P4500i The P4500i produces clean, inverter-quality power safe for sensitive electronics like laptops and audio systems, while still handling heavy loads like RV air conditioners, refrigerators, and power tools. At 52dB it operates about as quietly as a normal conversation, making it practical for campgrounds and residential areas with noise restrictions. The digital display shows remaining fuel level, estimated run time, current power load, voltage, and lifetime run hours so you always know exactly where the generator stands. It includes a dedicated 30A TT-30R outlet for direct connection to most RVs and campers, a standard 120V household outlet, and two USB ports. For situations that demand more output, you can parallel multiple units together. The P4500i is EPA compliant for use in the contiguous United States (not for sale in California). Best Use for the Cummins Onan P4500i The P4500i’s combination of clean power, low noise, and portability makes it a strong fit across a range of applications. The 52dB rating and inverter output make it ideal for RV camping where quiet hours and sensitive electronics are both factors. At 3.7kW continuous, it can handle power tools and lighting on a remote jobsite without a dedicated utility connection. It’s also a reliable home emergency backup for essentials like refrigerators, lights, and communications equipment during an outage. The portability and multiple outlet options make it equally useful for tailgating, motorsports, outdoor events, and food service setups. Solar and Battery System Compatibility While the Cummins Onan P4500i is a gasoline-powered generator, it plays an important complementary role in hybrid solar and alternative energy systems. You can use it as an AC input source for an inverter-charger like the MultiPlus-II 12V 3kVA to charge batteries, boost power output, or provide backup power on days with little sun.
