Buying Guide: Generac Home Generators

Almost all of the generators in the market claim to be the best for you. However, that is not the case. You must choose a generator that suits your needs to find the best one. For this, you need to make a list of all the critical features that you require and then find the right price as well. You don’t want to buy an overpriced generator just because it has all your desired features.

To help you out, we have listed down some important features required in generators.

Clean Electricity:

An essential feature to look at while buying generators is the fact that it provides clean electricity. If you are using the generator to provide power to home appliances like fridge, Computers, TV, etc. then using a clean electricity generator is an absolute necessity.

Clean electricity means generating electricity that will protect your sensitive appliances rather than making the appliances malfunction. Users should look for generators that include circuit breakers. It will make sure the power doesn’t flow if there is an overload.


If you are looking for a generator for outdoor power places like picnics and construction sites, then portability is a requirement. The generator must be light in weight, and the design should make it easier for you to carry it.

It would be quite helpful if the generator has handles and wheels to move it around quickly. This will make transporting the generator a convenience rather than a burden.


One of the significant concerns regarding generators is noise. Most of the time, the noise level rated on the generator is quite low than what the generator produces. It is often around the same noise level as a conversation. 

The constant noise of the generator can be quite bothersome for a few. Suffice to say. Noise levels are relative to users, so it just depends on you and what you consider comparatively quieter.

Some generators come with an eco-mode that lowers the noise further, and the auto-adjustment of the engine also allows you to decrease the noise levels. You can do this when not too much power is required.


The motor is the main power generating component of the generator. You must thoroughly check the motor before buying a generator. Motors usually claim to produce clean power or sine wave electricity. One should check if it is keeping up its end.

Another thing to check is the time. One must note down how long the motor runs on 25% 50% of the load. A good motor will run for 5 to 6 hours on a 25% load.

Users should look for 4 stroke engines, which would guarantee much better performance than standard engines.

Control System

What use is a high tech machine if you don’t find it easy to use it. Before you buy a generator, ensure that the buttons and controls are all easily understandable. Try to choose easy tools that have easy control systems.

The engine and oil indicators must be prominent to identify, and the generator must have ample AC and DC outlets. Make sure the generator has multiple starting options. In the case of harmful weather patterns, one of them might not work, so there is another option.


Generators have become a household necessity. If you are living in areas with frequent power outages or make frequent camping trips, then a generator is an absolute necessity for you. In the midst of it, choosing the right generator can be a bit tricky.
