#3. Generac XD5000E 5,000 Watt - Portable Diesel Generator

Modern diesel generators are known for being more efficient and providing a long life while requiring less maintenance. The Generac XD5000E is one perfect example of these diesel generators.

It's a mid-range model of high-quality standards and offers great power and reliability, factors which have made it stand out against the best diesel generators that the market has to offer.

Under the hood of the unit is an air-cooled 435cc Yanmar LW Series engine which is capable of producing around 5, 000 watts of continuous power and 5,500 watts of surge power.

That's sufficient output to keep almost everything in a house running in case of an extended outage. Beyond power, this Generac model guarantees balance and smooth operation with minimal vibrations.

It utilizes a direct fuel injection engine which delivers 9.3HP at a consistent speed of 3,600 RPMs plus it's counterbalanced to facilitate smooth operation even at such high speeds.

Therefore, vibrations which used to be a major issue with older diesel engines won't be a point of concern with this model.

Like many other diesel generators, the XD5000E is not an inverter but it does feature a true power technology which allows it to provide cleaner power compared to a lot of other diesel generators.

Despite the enormous output, this technology is able to deliver power with a total harmonic distortion of less than 5% which makes it safe enough to distribute clean and smooth electricity.

That means you can use it to power even the most sensitive electronics like your smartphone and computer without having to worry about them getting fried by surges.

Another thing that stands out in this Generac XD5000E model is its incredible runtime. It has a 12-gallon fuel tank which is really generous and ensures continuous power supply for a long time during an outage.

Operating at 50% load, the unit can run for up to 32 hours straight which means you can use it for a whole day from morning to morning before you have to refill it. At full load, it can go for up to 16 hours which is still a decent runtime compared to that of similar models.

It's one of the best fuel-efficient diesel generators available in the market and it comes with an automatic shutdown feature, so in case the oil level gets too low, it will immediately shutdown.

Operating this generator is also no hassle at all. You can use either a push-button electric start or a recoil pull start to start it both which are straightforward. The unit also features a compression release lever which makes it easier to start it in cold weather.

However, the battery for the electric start is not included which is unfortunate plus there's no remote start option. Another notable downside is weight. At 254 pounds, it's quite a heavy unit which considerably limits its portability.

The good news though is that it features a dual grip handle and 2 never-flat wheels to make it a bit easy to move. Further to this, it's equipped with an integrated lifting eye to allow you to bring it anywhere you want.

Noise will neither be an issue as the unit utilizes a set of high-quality mufflers which help make it quite and suitable to use in most neighborhoods.

Overall, considering the powerful engine that produces clean power and the longer runtime, the Generac XF5000E indeed represents excellent value for money. It's a solid, reliable diesel generator that's efficient, quiet and durable.

It's good enough for not just home use but also for most outdoor applications like powering electric power equipment and tools if you have a small garage or workshop.

Best 5000 watt generator - Buyer’s Guide

Once you have your shortlist of generators, it will be a lot easier to make an informed choice. The right 5,000-watt generator depends on what kind of power source and budget that are most important for you!

What Can I Run With A 5000 Watt Generator?

A 5000 watt generator can power an entire household in a blackout or storm, except for air conditioning and heating. Other common uses for a 5000 watt generator include powering tools at construction sites, tailgating before football games, camping trips, RVing, grilling out by the poolside on hot summer days... the list goes on and on!

Quiet Generator 5000 watt - which one to choose

The quietest 5000 watt generator is the DuroStar DS7000Q. This model has a high-efficiency muffler that makes it much quieter than most other generators of this size. It also uses fuel efficiently (so you don't have to refuel as often), and its eco mode means all but one light on the control panel will shut off during operation, so you can reduce noise even further!
