Electric Generators Direct Recommended

The Generac Protector 48 kilowatt is considered the "money is no object" whole house generator.

Yes, it's expensive. But, it's the ultimate whole house solution for several reasons.

1. 200-Amp of Electricity
The Generac QuietSource replaces all 200-amps of electricity supplied by the utility company. Sure, you may not use all it. But, it's there if you want it.

2. 1800 vs 3600 RPMs
The Generac engine runs at half the speed, resulting in less fuel consumption, less wear... more

Very Nice Generator Unit
This is a top of the line generator that is very quiet for it's size. The unit installed easily and worked as advertised. The only down side to this unit is the cost of the unit itself. If you want to push a full 200 amps this generator is what it takes.

Dependable Product
I've installed almost 500 standby generators in the last six years and I trust Generac to be the best. I have purchased many generators and accessory items from EGD and I find their price, availability and service to be above par. This particular 48kW unit had to be configured for LP gas and once that was done it worked flawlessly upon start-up. I give EGD 5 out of 5 stars.
