The DuroStar DS10000EH is the first unit to feature an OHV Air Cooled Engine. Look around and you will not find another unit with this large of an engine. This powerplant produces the 10,000 watts of peak power that feeds the fully functional power panel. A newly added feature is the Idle Control (referred to as Auto Throttle) which enable the motor to maintain RPM's under varying loads. This help maximizes fuel efficiency while minimizing the noise output. By utilizing an engine, the DS10000EH can handle heavy electrical loads as well as easily power multiple small load appliances simultaneously.
