Pros and Cons of Propane Generators
Before diving into our Buyer’s Guide, we wanted to cover the pros and cons of propane generators compared to diesel or gas-only generators. See best gas generators.
Propane generators are typically dual fuel, meaning you can also run them on gasoline. However, they’re significantly more expensive than a gas-only generator.
So why is it worth investing in a propane generator?
Advantages of Propane Generators
- Propane generators start easily in all climates, including cold temperatures
- Propane burns cleaner than gas or diesel, producing half as much carbon monoxide as gasoline
- You can store propane in a tank on your property, so you don’t have to worry about filling up at a gas station – Read how much propane does a generator use
- Unlike diesel or gasoline, propane doesn’t degrade over time making it easier to store
- Propane generators require less maintenance and are a better option if your generator only gets infrequent use
- Propane generators are quieter than gas or diesel – Read how to keep a generator quiet
Disadvantages of Propane Generators
- Propane generators are less efficient than gas or diesel, so you’ll burn more to get the same power output
- Propane is less readily available if you run out
- Propane engines have a shorter life expectancy than diesel or gas generators
- It typically costs more to run a propane generator
Conventional vs Inverter Generators
Most large generators you come across are the conventional kind with a large steel frame, fuel tank, and wheels for maneuverability. They are cheaper and more powerful than inverter generators and likely to be the best option if you want an emergency power source for your home.
However, inverter generators do have some advantages. Although they’re less powerful, they are more efficient, giving a longer run time. They’re also much quieter than conventional generators and produce fewer emissions.
The main benefit of an inverter generator is that it produces “clean electricity.” Whereas a conventional generator produces AC electricity, an inverter produces AC converted to a DC, then back to an AC. This means that the current produced is much more stable, making it a better option for charging sensitive electronic devices.
Generator power output is measured in watts. When shopping for a propane generator, you want to look at the continuous power output rating and the peak power output.
The continuous output provides power for the normal working load. The peak output enables appliances to draw on the additional capacity for a short period of time when starting up.
But how do you calculate how much power you need?
First, you need to know how much power your appliances and electronic devices need to run. Add these up to get an estimate for your total power requirement. This will help you decide which generators meet your requirements. Don’t forget to take into account the additional power appliances need when starting up.
To give you a rough idea, a 5,000-watt generator should enable you to run a refrigerator, sump pump, TV, microwave, and some lights. Heaters and air conditioning units typically draw a lot of power, so it’s worth thinking of alternative ways of heating and cooling your home in an emergency.
For a more accurate calculation, have a look at our generator size calculator.
Connecting a Generator to Your Home
If you want to use a large generator (5000 watts or more) to power hardwired appliances, such as a water heater or well pump, you’ll need to install a transfer switch. This looks a bit like your circuit breaker panel and allows you to select which circuits you want to power from your generator. Rather than connecting lots of appliances (or extension leads) directly to the generator, you have just one cable running between the generator and the transfer switch.
Installing a transfer switch isn’t cheap. An interlock device is a more affordable option, specific to your generator model, but you’ll still need to get an electrician to fit it.
