Sturdy, Aluminum enclosure with RhinoCoat™ are naturally rust and corrosion resistant. For salt air or high humidity conditions, aluminum is highly recommended to ensure decades of worry free service.
External “At-a-Glance” indicator lights offer an easy way to tell generator status without opening the generator enclosure.
Added Sound Reduction with enclosures that are lined with sound reducing foam panels for further noise reduction.
Hour Meter monitors run time, providing information to determine maintenance intervals.
Easiest installation on the market and an excellent value when purchased pre-packaged with a pre-wired transfer switch, or customize your system by purchasing the generator and transfer switch separately. Composite mounting pad is included, eliminating the need to pour a concrete base.
