10kw Standby Generator System
Install was on a pre existing 200 amp residential service. The prewired 100 amp, 16 circuit transfer switch, and premade 30 ft generator whip, made the installation a breeze. The home is located outside of town with LP rather than NG. Conversion was simple and piping installation went smooth because of the included 1" x 12" flexible line. Installed battery from local supplier and cold weather kit. Temps regularly drop below 0 deg F here in Wisconsin.

Pros: Easy To Use, Exceeded Expectations, Fast, Reliable

Not What I Expected
This product was not what it was advertised to be. The circuits in the transfer switch are not as stated in the brochure. The wiring diagram is horrible.
Cons: Bad Instructions

It Works
Arrived intact, no shipping damage. The manuals are for someone that has experience in electrical work and that can read wiring diagrams. The generator display is inconvenient to read. Have to sit on the ground. You have to disassemble the cover panels to do maintenance.

But all in all, it does what is expected. Comes on upon utility failure and provides power. So far, I'm pleased.
Pros: Easy To Use, Price, Light Weight, I'd Buy It Again
