Received our order in about 3 weeks, which shocked us after the supply problems of the past year. Had it installed by a certified Generac electrician, who recommended a test run of 24 hours. Just completed it and we’re highly impressed with the results. No noticeable drop in available power in our house, even with AC running some. Fuel consumption was much less than we anticipated, as well. If it functions as reputed and for as many years, it will be a worthwhile investment. Time will tell.

Previous models had service receptacles on generator. This is not a part of this delivery. Wi-Fi is great addition but not used to it’s potential.

With an installer it was easy.

Great unit, runs entire house, including heat pump. Consider using a Genpad base. Makes install a breeze.

Love always having power.

The generator was delivered from Home Depot sooner than expected. Worked with the Home Depot recommended installer, Beck Electric. They did a phenomenal job. The Wi-Fi shows the status of the generator. Started the first time when they mimicked a power outage. Took about 30 seconds for generator power to transfer to the house. He seamless transfer back to normal power. Very pleased at this point.

Generac generator is great. The confused part was trying to get the people at HD to find it after they notified me that it was in.

It’s installed and runs the tests fine. Only had a month and haven’t needed it yet. It was missing facia trim pieces and the company is a real pain to get them on the phone. It’s taking lots of calls to get them to send replacements. So customer service hasn’t been very good so far. But I did find a local Generac service company that is good to deal with. Home Depot got the generator in earlier than projected. HD was the only place I could find the generator. The big box blue store took my order and 1 wk from estimated delivery it cancelled with out of stock. But HD was great to work with.
