Essential Components of a Home Generator

It is quite easy to start discussing the working of a generator, but what if you do not know the main components of a generator? Therefore, we will first discuss some of the most important components of a home generator.

1: The Engine (Internal Combustion Engine)

You would probably know that a home generator, whether heavy or portable, has an engine. This engine is responsible for creating all that raw power that produces electricity. So, without an engine, a generator is not a functional generator.

Now, coming to the type of an engine and its working. The engine that you get with a generator is a 4-stroke air-cooled engine. The working of this engine is similar to any other internal combustion engine.

Like most vehicles, this engine runs on either petrol or diesel. In short, a fueling system is there, and you have to top it up to generate electricity. Furthermore, most of these engines require engine oil (which must be replaced at regular intervals).

So, the maintenance is there, but it does not take too much of your time. Only after some usage, you have to replace the engine oil. Rest, there is no special maintenance required.

2: The Alternator

Though the alternator of a generator is counted as the second essential component, a generator is nothing without an alternator. Why is it so? Simply because an alternator converts that mechanical energy from the engine to electrical energy.

This electrical energy is what your home appliances demand and run on. So, in simple words, alternate takes that mechanical energy and converts it back into AC (Alternating current).

3: Electric Starter

This specific component should be pretty much understood. Anyhow, the electric starter is the starting motor of your generator. It is directly attached to your generator’s 12 V DC (Direct Current) battery.

So, its job is to start the engine of your generator. That’s pretty much it.

4: Power Outlets

There are power outlets available on all types of generators. This power outlet will be delivering electrical power to your home appliances.
