Can a Solar Generator Run a Furnace? (Furnace + Generator Examples)

Furnace units are essential parts of a building, especially in regions where you may need to keep warm during winter or harsh weather conditions.

As compared with the conventional furnaces used in olden times, most heaters now run on electricity.

Solar generators are also a vital part of our lives. Apart from being a requirement for camping and outdoor life, they serve us in cases of power outages or blackouts.

Hence, solar generators have established their position as a reliable alternative source of electricity for human use.

Considering the importance of furnace units and solar generators, a question arises. Can you power your furnace units at home with portable solar generators?

This question remains important because most furnace units run on electricity. In the case of power outage or blackout, can solar generators step up to power the furnace units? There is a simple answer to this question.

Yes, some furnace units and several portable heaters can be powered by solar generators. However, not all furnace units can be powered by solar generators. Electric boilers or furnace units require a powerful continuous source of energy. Generators as powerful as 10 KW are needed to power them; hence, they cannot be powered by solar generators.

In this review, we are going to examine different types of furnace units and heaters that can be powered using portable solar generators. We are also going to discuss the criteria for choosing solar generators that can power furnace units and heaters.

Powering a Furnace Unit With a Solar Generator

While a solar generator can power most furnace units, some furnace units cannot be powered by solar generators. In this section, we will discuss why some furnace units can be powered using solar generators while others cannot.

In other words, we will examine the factors that determine whether or not solar generators can power the furnace units.

As a general rule, you cannot run electric furnace units or boilers on portable solar generators. This is because they consume a lot of electricity, which cannot be supplied by portable solar generators.

An average electric furnace unit requires as much as 10,000W. It is rare and almost impossible to find a portable solar generator with that capacity.

Furthermore, it is vital to consider your furnace unit’s rating and wattage while selecting a portable solar generator for it. An average gas furnace unit or boiler utilizes about 600 watts of electricity.

Hence, the capacity of any solar generator that will be used to power the furnace unit must be well above 600 watts.

It is advised that a generator with a capacity twice the wattage of the furnace should power it. This is to prevent overloading of the generator when other household appliances are plugged in.
