Westinghouse14500 Peak Watt Tri-Fuel Home Backup Portable Generator, Remote Electric Start, Transfer Switch Ready, Gas, Propane, and Natural Gas Powered

Thus far, I am thrilled with the product, performance, and delivery. I've had it 3 weeks. I completed the 5 hour break in period at <50% output capacity, oil change, then 1 more hour of testing and power usage measurements up to the 40 running/50 peak amp max capacities on natural gas*. I intend to continue using only Natural Gas. I can run my entire house including 2 central A/C** and a pool pump.I do get a quick, sub second flicker when the central A/C unit starts, but it's not long or deep and no worse than when I'm on utility power. I have mostly LED lights and the power definitely seems cleaner than my previous portable gasoline generator; no constantly flickering lights or humming sounds.I agree with other's comments. Although it is heavy, it is easy to move/maneuver once you have it assembled with the wheels(No, it does not come assembled). It is noisy, but no louder than my previous portable gen.Delivery/Damage: I was a bit nervous buying through Amazon due to all of the delivery and damage issues in other reviews, but my experience was good. It does not come on there regular delivery vehicles. Given the weight, I could see how easily it could be dropped, damaged, etc... I think it boils down to the quality, physical strength, and equipment(like a lift gate on the truck) of the delivery people/service.Mine came with a 10' natural gas hose, which is stated as "not included"- creating a return for one I bought separately.My only complaint is the charger/charger port on the generator, which sticks out when plugged in to keep the battery charged. I've already hit mine and bent it. I wish the end that plugs into the generator was flat or where it plugs in was recessed to protect it from damage.*Natural Gas: You need 5-7 inch in water column gas pressure; anything less and it may not run well or may not run at all. Pipe/Hose size and distance from your gas meter matter, impacting the energy generation capacity. The longer the distance, the diameter of the pipe/hose increases for the generator to be able to provide the maximum 12k/9.5k watts on ng. If it starts OK but you experience brown outs, engine sputtering like it's about to stall, long/heavy dimming when you start heavy loads like air conditioners, pumps, some microwaves, etc.... it is likely your hose/pipe diameter is too small for the distance from the gas meter. I personally experienced this with a 3/4" 100' long line. When I moved it closer with a short 3/4" 50' long line directly off a lower pressure port at the meter - I no longer had such issues, even when reaching the max capacities.**Central Air Conditioning:I am able to run everything in my 4k sq ft home, including both of my 2.5 ton central A/C units at the same time. I do have MICRO-AIR EasyStart FLEX 398 soft starts installed on both AC units, which lowers the LRA(starting amps required) from 72.5 to 24.6 amps. If both compressors started simultaneously, I would likely exceed the 50 amp peak natural gas capacity while running the regular load from the house simultaneously. But, I think the chances of them starting exactly simultaneously are slim. While running, they each pull approximately 5 amps each - so having both running at the same time isn't a problem for my home. During a real outage, I would likely only run one A/C unit for the area of the house we are using to minimize fuel consumption.My supplemental heat source in the winter is natural gas, so I cannot speak to how it would accommodate electric. "Supplemental heat source": additional heat source used by your furnace to add to our replace the heat from the heat pump when it is very cold and cannot provide enough heat on its own. Additionally I also cannot speak to how well/if it could accomodate a fully electric heat furnace.I rarely write reviews, but a great deal of research and time went into this. I hope this helps guide someone else, or at least gets you started.

Great Generator, was able to power my 5-ton AC with a soft starter installed no problem, along with 2 refrigerators, and tv when hooked up to my panel through the 50amp plug. Power was very stable, no issues with any LED bulbs flickering or other electronics not functioning. It fired right up on the first go, its loud but I think that's par for the course with traditional generators of this size. I look forward to getting my natural gas plumped for this to be prepared for hurricane season. It comes with a remote starter which is a plus. One thing that wasn't super obvious from any instructions is that if you are running this to back feed a main service panel, you need to unbond the neutral from the ground on the Generator. This involves taking off the cover of the alternator and removing a small green and yellow wire that bonds the neutral to the chassis. This was hinted at in the owner's manual but asked the reader to refer to local regulations, but unbonding the generator seems to be a pretty widely accepted convention in the US. This may or may not be applicable if you're using a transfer switch between the generator and panel. In all, great generator for the money, performs as advertised.
