I recently purchased a 20kw home generator and I’m here to tell you how to pick the right one. First and foremost, consider your power needs and the size of your home. Do you want to power all appliances, lights, and other necessities or just a few? Once you know your power requirement, you can begin to look at the different types of generators available.

Next, look for features like automatic start, self-diagnosing systems, and noise reduction features. A generator that automatically starts when the power goes out is a great feature to have, as is one with a self-diagnosing system that can detect when something is wrong with the generator. Additionally, noise reduction features can help keep the generator from becoming too loud and disruptive.

Also consider the warranty, as some generators may come with a limited warranty or none at all. Additionally, find out how long the generator is expected to last. The longer the expected lifetime, the better.

Finally, consider the cost. A 20kw home generator can easily cost in the thousands of dollars. Make sure you shop around and compare prices to find the best deal.

Overall, choosing a 20kw home generator can be a daunting task. But by taking into account your power needs, the features of the generator, the warranty, and the cost, you can make an informed decision and find one that will best meet your needs.
