If you need good power, you’ll have to select a high-power generator. That’s why we are going to disclose some of the pro tips that will help you to get the best generator.


Power output

The most crucial thing that you check before buying a generator is power output. Consider buying a generator according to your power requirement. It also depends on house appliances. If you have high-power appliances in your home, you need a high-wattage generator. For example, 3500w to 5000w is enough for a small house. However, for a big house, you need a 10000w to 120000w generator.


There are online power calculators for generators that can be used to have a better idea of your power needs.


HP Rating

HP rating means the horsepower rating of a gas engine. This is another important aspect that should not be ignored. Check the HP Rating of a generator before making a choice. 10 is a standard HP rating for a generator. However, some good-quality generators have more than 14 HP ratings.


Output ports

You’ll connect devices to a generator to power them. Therefore, it is necessary to check out the output port of a generator. Generally, Ac ports, Rv ports, and transfer switches are available in a generator. But some manufacturers provide USB ports too.


Engine Capacity

Generally, the whole house generator is equipped with a gas engine that produces electricity. It is essential to check the engine capacity. If you are not very technical and don’t know how to check engine capacity, you can check the cc of an engine. CC stands for cubic centimeters. You should try to get a high cc engine generator as it will be more efficient compared to the lower cc engine.




What power capacity is suitable to run a whole house?

There is no exact answer to this question as power consumption varies from person to person. If you have heavy-duty appliances, you’ll need a high-power generator. It is estimated that a 7000w to 10000w generator can be good for the running of the whole house.


Are whole house generators durable?  

Whole house generators are reliable because they need frequent maintenance and they have a long life span. In short, you can trust a whole-house generator.


Is it hard to install a whole-house generator? 

Honestly speaking it is neither hard nor easy. It depends on the person. If you have prior knowledge, you can install it by yourself. However, if you do not know how to install a whole-house generator, it is recommended to hire a professional to avoid any mistakes. Because there are many tasks that an ordinary person can’t do such as electric wiring. It is better not to take a risk and hire an expert.
