#1. Westinghouse WGen12000 Portable Gasoline Generator with Electric & Remote Start

Westinghouse is a well-known brand in the portable generators industry and it has a series of high-quality models under its name. The WGen 12000 is one of them.

Westinghouse WGen 1200 is a top-performing portable generator specifically designed for heavy-duty usage a fact that makes it one of the best choices for anyone looking to power the whole house.

With a tough and very powerful V-Twin engine, this Westinghouse generator has a whopping 15,000 watts of peak surge power and 12,000 running wattage.

Due to these large amounts of power, the WGen 12,000 can easily run almost all of your home appliances from small appliances to large electric equipment like garage door openers, light, heating, well pump, refrigerator, and even microwaves.

It can meet your household power needs and features a variety of outlets including, four 5-20R GVCI household outlets, one 14-50ZR receptacle, one Lf-30R outlet, and two 5V USB ports.

In other words, you will be able to power all your household essentials with ease plus all the outlets have rubber covers for added safety.

The alternator is equally a heavy-duty unit and comes equipped with an automatic voltage regulator (AVR). What's really impressive about this kind an alternator is that it has a very low Total Harmonic Distortion (THD).

Most non-inverter or rather standard generators often produce THD levels above 20% which end up damaging sensitive electronic equipment.

The WGen 12,000 has a THD level of less than 5% which is perfectly safe for electronics although not as good as quality inverters that usually have THD levels of less than 3%.

For a generator that has to run all day long, a fuel-efficient engine coupled with a large gas tank is essential. The WGen 12,000 does not disappoint in this area.

The powerful V-Twn engines are very efficient and the unit features an enormous, 10.5-gallon tank. In other words, you are guaranteed long runtimes.

At a quarter load (an average load of 25%), it can run for 16 hours and when used at half capacity (50% load), ut can run up to 11 hours straight. These are no doubt very impressive runtimes for a unit that's pushing out around 15,000 watts of power.

You will also appreciate how low the fuel consumption is with this Westinghouse generator. For consumes one gallon to generate 6.3 KWh which is much better compared to the average fuel consumption for many similar portable generators out there.

Starting this generator is also pretty simple. It utilizes an electric starter which is just a simple push of a button. It's also equipped with a recoil starter that serves as a backup.

Even much better, the WGen 12,000 offers the convenience of using a remote control to start the unit from as far as 100 yards away.

That's something extra that you are not likely to find on most generators and it means no more walking back and forth so as to start or stop your generator. One common issue with a lot of heavy-duty units like this is that they tend to produce so much noise.

The WGen 12,000 is not the quietest but it does have a low idle mode that helps keep the noise levels fairly down to about 74 dB which is not that bad at all considering that it's an open frame generator.

In general, from its construction to its immense power and superb engine, this Westinghouse WGen 12,000 is undoubtedly built for nothing but heavy-duty usage.

If you are in search of a reliable generator that can effectively power your whole house, then this is an option that's certainly worth checking out.
