The unit installed pretty easily. The electricians said that there was plenty of room (better than others) for internal wiring hook up and battery installation. Since exhaust was through the front panel, physical placement of the generator was a bit more flexible. I really like having a "smart system" like this where the transfer switch can temporarily shut off lower priority circuits during periods of peak power use. Essentially the entire house has electricity during power outages. The transfer switch comes with an internal load shedding capability for the air conditioning system and additional load shedding circuits are easily added by installing separate power control modules. In the case of our house, the electricians set up load shedding for the AC and two other high-power circuits. The generator control panel is simple to use. I was also impressed with how quiet the unit runs. Given the sales price and the extended 10 year warranty for parts and laobr, I consider this generator to be one of the best buys out there.

Unit came ready to install. All we needed to do is hire an electrician and find a good spot outside our house. Delivered complete except for battery (car size) which I had to purchase separately. Heavy oversized pallet deliv so watch out for that surprise. Took 3 big men to move.
