Inverter system with Pulse Width Modulation

This industry-leading system produces high-quality, clean electricity. Its pure sine wave is as clean as or cleaner than commercial power, making it suitable for products with built in microcomputers

Noise Block™ acoustically designed sound reduction system

The full generator enclosure uses sound absorbing material in key internal locations. This design, combined with a newly designed muffler and molded fan, ensures unbeatable noise reduction.

Smart Throttle™ load-sensing throttle control

This intelligent system automatically adjusts engine speed to precisely match load - resulting in greater fuel efficiency and noise reduction.

Dual coil alternator stator

By lowering engine speed, this exclusive technology produces a number of benefits including reduced noise, fuel consumption and engine wear.
