Engineered specifically for off-grid use, our EcoGen Series automatic standby generator is your green solution for affordable, reliable, low-emission, off-grid standby power.
Greener, Efficient, Abundant
Clean-burning propane fuel increases efficiency, contributes to longer engine life, and produces significantly less carbon monoxide than gasoline-fueled engines. Propane gas can be stored indefinitely and is available at many off-grid locations.
Our exclusive premium oil-recovery and circulation system virtually halts the oil degradation, resulting in greatly extended maintenance intervals—an unprecedented five times the industry standard, with 500 hours between oil changes.
At least 10 dB(A) quieter than competitive units and significantly quieter than a standard portable.
Purpose-built for the rigors of generator use, and requires significantly fewer scheduled maintenance checkups than competitive engines.
Easily control generator diagnostics and get information at a glance with Generac’s user-friendly Nexus™ Controller—the most comprehensive controller available.
It can be summed up by saying that Keystone has truly been the easiest and most accommodating company to deal with at my summer cottage at Crystal Lake. Thank you for that.
