Best Dual Fuel Inverter Generator

There are three kinds of generators in terms of fuel: single fuel, dual fuel, and tri fuel generators. 

Dual fuel generators are expensive upfront but cheaper in a longer run than single fuel generators due to less cost of propane. Dual fuel generators give flexibility in choosing fuel type. There are differences in propane and gasoline, which are given below.

Gasoline	Propane
On gasoline, the generator produces more power	On propane, the generator produces less power
Gasoline is more expensive	Propane is cheaper
Gasoline produces excessive toxins	Propane releases fewer toxins
Gas must be kept in an extra amount	Your home may contain a propane tank for other purposes

Inverter and simple generators differ in many ways. Inverter generator provides true sine wave current who’s THD is less than 3%, which is required for sensitive equipment.  

In this article we gave a wide range of best dual fuel inverter generators. We made categories on the basis of output power ranges from 2000 to 9000 watts. In each category we have given the best possible choice available in the market.
