    Key Things to Consider When Choosing the Best Whole House Generator

    Whole House Generator

    There are certain things you should focus on before adding a whole-house generator to the cart. This buyer guide makes it easy for you.

    Noise Level

    You'll find whole-house generators that come with special features to ensure they're less or not noisy. Some units are extremely quiet such that you can't even notice that it's operating.

    Choose the generator that's housed in a case and have sound-dampening lining. This ensures generators work less noisy and no louder than 59db. Despite that standby generator is less noisy, never miss to check out its decibel rating.

    Transfer switch

    It's equally important to focus on the transfer switch. You can easily install a manual switch to control your portable generator. However, if you're going for a whole-house generator, then it features an automatic switch that helps you to detect power outages.

    It turns the unit automatically. In most cases, a 200-amp switch is perfect for your home. Most models in our list come with both 100-amp and 200-amp switches. So, when selecting, match the transfer switch amps according to your needs.

    Portable Vs. Standby Generator

    One thing, choose between a portable and home standby generator. Both models perform the same thing, but they differ in some aspects. Noticeably, portable generators are lightweight and easy to transport.

    Contrary, standby generators are stationary. Also, portable generators are not only louder but also produce less power than whole house generators.

    Additionally, home standby generators come with insulated weatherproof housing hence safe. They start up automatically, while you must turn on portable generators manually.

    Besides, standby models are expensive but can serve you for days or weeks.

    Power Output

    What's the intended use? Be aware of the household appliances you've, and you want to power up. Then, select the model that can run those items and appliances during power outages.

    Approximately, an 8KW generator will serve power to the whole house. However, you're recommended to select beyond 10KW.

    Safety features

    Carbon monoxide leakage is very high in some models. That's why you must choose one with ideal features. For one, it should feature a power-transfer switch where you connect a 3-prong cord and circuit breaker. Beyond that, the fuel source should be well sealed with a container to avoid leakage.

    Warranty

    It's good to note that models don't come with the same length of warranty. A whole-house generator with a lengthy generator is worthy.

    Since you're investing 4000 dollars or more, go for a longer warranty. Some even offer a 10-year warranty and excellent customer service. Other manufacturers give a 5-year warranty.
