Let us explore some of the important considerations surrounding tiny house generators before we explore our top choices.

What Size Generator Do I Need for a Tiny House?

The easiest way to do this is to call an electrician for an energy audit of your tiny house with all your appliances already in place. If you would rather do this yourself, you need to evaluate your recent electricity utility bill to get a broad picture of the current electricity consumed in your house.

Once this is determined, subtract the appliances you would no longer need and add any new appliances you plan to use to get the total.

On average, you will need anywhere from 3,000 to 5,000 watts to power a tiny house.

If you live in a tiny house and want to power an additional shed, two tiny houses, two trailer houses, or run electricity to some high-power tools off the grid, then you will need a tiny house generator with an estimated output of 10,000 to 12,000 watts.

A high-wattage gas-powered generator offers the possibility to live off-grid without cutting yourself off from using some modern appliances. You can keep the lights on in your tiny house and still have enough power for other activities. 

If the sound they produce is your biggest issue, then you can use a soundproof shed to reduce the noise pollution or purchase a tiny house generator that produces 60 dB and lower for your tiny house.

Now that you understand the right size to pick for your tiny house generator, let us get right into our best picks for all off-grid living conditions in 2022.

Ultimate Buying Tips for Your Tiny House Generator

In addition to our top five best picks, we have outlined the following buying tips to ensure that you are picking the right portable generator for your needs.

Buy One with an Electric Start

The beauty of an electric start is that you can easily start the engine at the push of a button. This can come in handy when in the middle of the night or when you need electricity backup in an emergency. It’s not a make-or-break feature in tiny house generators but one that is worth considering.

Consider Standby Hours on a Full Gas/Propane Tank

You should pay a lot of attention to this feature, so you don’t end up overpaying for a portable generator that guzzles up your fuel source. What you need is something that efficiently maximizes the fuel to give you up to 7 to 15 hours of run time on a full tank, depending on the tank size. Ideally, a 4-gallon tank should run for at least 15 or more hours on a full tank.

Alternative Fuel Capacity

Flexibility is always a welcome choice when living off-grid in a tiny house. Tiny house generators with alternative fuel capacity, will come in handy when you cant get your hands on one of the fuel sources, either gas or propane. 

Automatic Carbon Monoxide Shutoff

This safety feature helps to reduce the risk of carbon monoxide (CO) poisoning. It is an inbuilt feature that automatically shuts the portable generator off when the CO levels are critically high. This feature is a must-have on any modern tiny house generator.

Buy One with Multiple Electrical Outlets

This feature is increasingly useful outdoors and off-grid. With multiple electrical outlets, you can spread the load to different units, like sheds, additional tiny houses, and more. With multiple outlets, you can also easily share the load more effectively. With this in mind, you should buy one with four or more outlets.

When you decide to pick up your tiny house generator, make sure you go through the buying tips we have highlighted here. The other features like low-oil shutoff and fuel gauge or indicators are increasingly common in today’s generators, so you shouldn’t have any problem there.
