Aurora Generators 12kW Yanmar Diesel Generator/ No Canopy Enclosure - PowerGen USA - AGi12Y-O

THIS SIZE GENERATOR IS PERFECT FOR most homes. 12-13 kW allows you to keep everything running with the limitation of possibly not allowing you to use all your heavy appliances simultaneously. For that, we suggest a larger 20 kW Generator

JUST TAKE A LOOK AT WHAT YOU GET:

Long Runtime Diesel-powered engines can work hard 24/7 for extended periods - up to 3 weeks if necessary - and still outlast any other type of engine for a fraction of the operating costs. 

Reliability 

There's a reason the farming, transportation and construction industries have been leveraging the benefits offered by diesel generators for years.

Home Friendly 

New stringent emission regulations have produced clean diesel engine options that fit perfectly for home power generation. These strong, reliable long-life diesel engines have become today's preferred choice for home backup power. 

Clean and Safe 

Diesel fuel is a cleaner fuel that can be safely stored for long periods.

Quieter Running 

The higher the RPM, the louder the noise. Our diesel generators run in the 1800 RPM range, unlike non-diesel products that run at 3600.

Low Maintenance 

You only need to change the oil and filter every 500 hours instead of every 100 hours for a non-diesel generator.

Cost-Effective 

Diesel fuel is the least expensive to run, with natural gas and propane costing much more.

Flexible Warranty 

Diesel-powered generators seldom have any restrictions on use and can be used non-stop if needed. The warranty for natural gas, propane and gasoline-powered generators usually only covers emergency standby use.
