Overview

Our Most Powerful Inverter Generator

Our DR PRO-3500iO is a “hybrid”, or open-frame, inverter generator. While it looks a bit more like a conventional portable generator, DR inverter technology makes it significantly quieter and lighter than any generator in its class.

And with Surge Starting™, you get the benefit of up to 50% more starting capacity, letting you start up and run additional devices that would overload many competitive products. This is a great unit for contractors who want to keep noise under control in residential neighborhoods.

This inverter was just the right amount of power I needed for my RV. I was impressed with how quiet it was for having an open frame.
