Whole House Generator
Solid machine. Purchased it after Helene. Love the large fuel tank and extended handles to wheel it around. This unit is well built. It is a little noisy but i can give that a pass as it is 28000 watts and 999cc engine. I would buy it again in a minute.It has one oddity. It comes with a remote FOB to start it. Its a great idea but you cant use it unless the battery switch is already on, the fuel switch is on and whatever you want it to power is already connected. The only bad part for me is that I plug it in to my house panel and i dont use ut except when the power goes out. So the fuel can go bad in the carb and the battery to start it could go bad.But to me that doesnt matter much. The ease of start, the 17 gallon gas tank, the power it provides (2 – 50 amp 220volt, and multiple 120v outlets), and the ease to roll around such a heavy machinemakes it a perfect machine for me.

Amazing Generator and Amazing Customer Service
This generator is all I wished for! I did not want to spend 14,000 dollars for a Generac, but I needed something that could actually light up the house, including AC units, Pool and Freezers for a week whenever the next hurricane comes. This is it. Huge power but still portable and at a 30% the cost of a generac. It is even more powerful than the Generac. It starts and stops super easy from the inside with a remote, it holds 17 gallons of gas so I don’t have to run to the gas station every two days. Also the Customer Service has been amazing. The battery was damaged on delivery, they replied super fast and sent a replacement at no cost and was super easy to ask for it, no hassle. This is a good company. So far I’ve had it on to test for a couple of hours and it is great, the noise is not bad at all, It makes the same noise a small one would make.

Works well – major power and great value – smooth starting
The product worked right away and was quickly cranking out 18000 watts for our house. I really like the electric start and the battery was full when it arrived as well. I installed to 50A inlets and connected them to the 50A outlets through a Generator cord. Works great–just make sure you get a good cord (NEMA, etc.)The unit, like most other large generators is loud, but we’ve been able to find a good spot for it where a some fencing blocks most of the noise from the main house.Beyond that, it IS very heavy. I can wheel it around on level ground in the grass but not up any sort of hill. I eventually used a very small winch to get it up a hill where we needed it to go. I was able to unbox it and set-it up without an other help.The best thing I like about this is the value. It lets me do whole house power, reliably, with dual fuel for less than $4000. As long as you’re willing to do a little work for yourself in set-up, I think it’s a great deal versus an installed whole home generator. I also like the flexibility of the dual fuel. I am planning on using propane as much as possible, but it’s nice to know that I can switch to gas in an extended outage, assuming I can drive out to the gas station and/or keep enough gas around.Overall very satisfied.

It’s a BEAST
Very easy for installation by an electrician. It took about 2 hours. This generator has 2 50 amp outlets so he installed 2 hook up power boxes— one for the main floor and one for the full basement. Just roll the generator out of the basement with the 2 power cords already plugged in, plug in the 2 power cords, turn off the main breaker ( I also turn off the 2 heat pumps and my hot tube), hit the EASY START BUTTON and we are in business. With 28,000 starting watts, the motor basically runs at idle speed which means it runs almost 17 hours with a 17 gallon gas tank. Great addition to our house!!! Also not as loud as I expected.

Poor customer support- Buyer Beware
If I could rate this with 0 stars or even negative stars- I would! I received this brand new Westinghouse generator on July 14, 2023. I spent $3600 for it. I followed ALL the directions in the start up manual step by step. It ran great for the first hour – now it won’t stay running. I followed all of the troubleshooting steps in their manual and all of the YouTube troubleshooting videos but still had the same results- it will not stay running. I called the 877 number and was given a case number #SC209026-“Generator” . That was a week or more ago. No response. I placed another call in the middle of this week and the recording said I was number four in the que. I never did get to speak to a representative. If I had known that this would be the case, I wouldn’t have spent my hard-earned money on their product or with their company. To say I am disgusted is an understatement. It would be nice if someone would get back to me concerning this. Until then- buyer beware.

Thinking about a Generac? Consider this.
Got this to power home for future storms and hurricanes. Just as powerful as a generac but only a 1/3 of what generac cost. I had electrician install 2 50 amp inlet boxes, interlock kit and a 100 amp breaker. With two 50 amp cables to the inlet boxes this powers a 3200 sq foot home with a 6 ton ac/ heat pump, 600 foot well, two refrigerators, every appliance and fixture in our home. We did a four hour test run after set up and this generator performed flawlessly. It’s heavy but easy to roll around. The alternator cover was damaged during shipping but I bent it back in shape and ordered a new one for $12.99 from Westinghouse. Amazon took 10% off the total price for my trouble. Was skeptical that it would power the whole home, not anymore. Zero buyers remorse on this purchase…I have also purchased a portable 48 gallon fuel tank and pump that our small tractor can lift on and off pickup truck. I’ll fill it up when hurricane season starts and use the tank to fuel generator mowers boat cars etc etc…we went without power for 8 days after Helene. We had a 7000 watt generator but we’re not happy with all the cord dragging 5 gallon cans of fuel every 8 hours…this is a much better set up, the electrician was very impressed by the quality of the generator as well. I also like the idea that its not permanently attached like a generac with a big propane tank. I can take it other places or let a friend borrow it…
