Yes,I think it's a good business but it depends on the location you want to set up the business.

If you live in Europe or other develope countries then you shouldn't even consider such business because these places have constant electricity that's why I said earlier it depends on the location.

Let's take for example Nigeria where electricity is a major issues, these are the kind of places suitable to establish this kind of business.

Generator business is a very lucrative business in Nigeria because of poor power distribution.

So if you are interested in starting a generator business of your own, you have to look for places where they have poor power distribution this are the places where your products will be patronize.
