Digital Hybrid Open Frame

The digital hybrid inverter design was created to bring you both the price and ease of maintenance of an open frame with the efficiency of an inverter. Inverters do not run at full capacity constantly. Instead, they will put energy out as needed. This is essential for any generator to run efficiently.

Many open frames tend to be very loud and disruptive, especially one as powerful as an 8750-watt generator. However, Champion designed their 100520 8750-watt powerhouse to maintain all the benefits of this hybrid model and reduce any drawbacks!

Push-Button Electric Start

This digital hybrid features an electric push-button start included. Plus, cold start technology allows for an easy start in all weather conditions.
