How Long Can Generac 20kw Run

Generac 7042

Of course, Generac says its larger generators can run for about 100 200 hundred hours, but we think that statement isnt realistic. There are factors that play a role in how long the generator can last. The first one is the fuel capacity of the generator.

No matter how strong it is, the generator will shut down when it runs out of fuel. And the filled tank can only carry the generator for about 48 to 72 hours.

Another factor is the rate of fuel consumption. The higher the load on the generator, the faster it will consume the fuel. Finally, to make your generator last long, it is not advisable to make it run for long hours without resting. If the power failure is expected to last for days, instead of running your generator for 24 hours every day, let it rest for at least 2 hours every day.

Youll be able to extend its lifespan that way. Remember, nothing shortens the life of a generator like wear and tear that stemmed out from heavy usage.

Why Is My Whole House Generator Draining Battery

A whole house generator is designed to be the primary power source for your home, meaning it needs to be able to hold a charge without draining the battery in order to function properly. If your generator is draining the battery, it may be an indication that something is not working correctly, like a faulty connection or a failing electrical component.

It can also be caused by a lack of regular maintenance, like not changing the oil, not checking the spark plug, or not tightening the terminals on the battery. If left unchecked, this can damage the generator and lead to further drain on the battery.

In order to avoid this, it is important to regularly maintain your generator and check for any signs of wear or malfunction, as well as having any necessary repairs done as soon as possible.
