An air fryer is a great addition to any kitchen. It’s a different way to cook foods that are crispy without the use of oil. If you using an inverter off-grid using a battery you’ll need to make sure the inverter can provide enough power to run the air fryer.
So can an Inverter run an air fryer? Yes, it can. In this article, we take you through matching an Inverter for your air fryer and choosing a battery to run alongside it.
What Inverter for an Air Fryer?
The most important thing to consider when choosing an inverter is its wattage capacity. Wattage is a measurement of how much energy an appliance uses over time.
If you’re looking for an air fryer that can cook meals quickly and evenly, we recommend choosing one with at least 1800 watts of power. The best way to find out how much power your new air fryer requires is by reading its manual or looking at its label, which will list its wattage (or volts).
You will need an inverter that is rated higher than the appliance. For an 1800-watt air fryer, you’ll need an inverter rating of at least 2000 watts. A 2000-watt inverter with 6000-watt surge watts is a powerful inverter that can run high-wattage appliances like your air fryer. You can also go higher to a 3000-watt Inverter.
What Size Battery for an 1800-Watt Air Fryer
To ensure the inverter provides enough power, it’s important to choose a battery with sufficient capacity. To size the battery we’ll first calculate the number of amps required and estimate the battery capacity in amp-hours
How Many Amps for an 1800-watt Air Fryer
To get the number of amps the Inverter will draw from the battery in order to power the Air Fryer you divide the Watts by the voltage of the system.
For a 12v system
1800W/12v = 150 amps
For a 24V system,
1800W/24v = 75 amps
How Many Amp-hours for an Air Fryer
Amp-hours is 1-amp of power expended over one hour. This can tell you if a battery can work for the intended use or not.
Batteries are not designed to be depleted over a short period of time. Most solar batteries are labeled deep cycle and are intended to be used over a 20-hour period max. But with LiFePo4 batteries, it is possible to stretch these limits as they have a 1C rating which means you can discharge the whole battery at once. This is not recommended however but a 50% discharge in one hour is possible.
So if we were to use a 24v 300Ah LiFePO4 battery bank (or more) it can support the 75 amps draw from the air fryer for one hour of use.
The battery will not be fully depleted and you can use it to run the air fryer for longer or even use another high-wattage appliance like a space heater on the inverter.
What size Battery for different settings on the Air Fryer
As stated before there are different settings and times on an air fryer for different foods. From what we’ve calculated as the requirements for an hour we can estimate the power needed to run the air fryer for other periods of time.
| Food | Length in time | Watt-hour Requirements | Battery (24v) |
| 1 hr | 1800Wh | 300Ah | |
| Baked Potatoes | 30 minutes | 900Wh | 150Ah |
| Chicken Tenders | 15 minutes | 450Wh | 100Ah |
| Brocolli | 10 minutes | 300Wh | 50Ah |
