What to look for in 15000-Watt Generators – Buying Guide

There are so many 15000-watt generators available on the market. So to choose the best one for you, consider the following points while shopping.

Fuel

Portable generators often use gas and propane. Gas will be cheaper in the long run, but when you are in an area that is frequently hit by natural disasters, gas can be difficult to find. But in addition to this drop, gas is also simple. A solar power generator is suitable for smaller applications.

There are also hybrid generators that use both gas and propane if you need alternative sources of fuel when needed. So when buying your generator, make sure it runs on gas or propane.

Fuel Economy

You should see how many hours the fuel tank can supply the generator before starting it. Most gas generators are 25% or 50% loaded. To give you an example, if a gas generator can run 20 hours at half load, it can run 10 hours at full load. You should take this into account when choosing your generator.

Design Quality

The quality of the generator is important because you need to make sure that it is durable and reliable. The design should also be good, especially if you take it with you to a sturdy workspace. In your workplace, you probably want to look for one with wheels and outlet covers so nothing is screwed up.

If all you’re looking for is a backup power supply for your home then having all the conveniences probably doesn’t matter as you will only be using them for power.

What to look for in 15000-Watt Generators

Noise

Gas generators tend to be noisy. If you live in the middle of nowhere, that’s probably not a big deal, but if you live in a residential area, noise can be an issue. Since the generators we are talking about today are 15,000. Due to the high output, watts are one of the loudest by default.

You can use a generator cover or exhaust to make the generator quieter, but you need to consider where you are going to live or use the generator as it will be noisy.

Warranty

If you are investing more than $ 2000 in a generator, you definitely want to make sure it has a good warranty. You should also make sure that you are getting good customer service in case you need to troubleshoot your generator.

While most generators require minimal maintenance, you still want a guarantee in case something really goes wrong.

The good news is that most generator warranties are around 13 years and depending on whether you use it at home or at work, you will likely see a different warranty for it.
