An Electric kettle is a common household appliance. They’re used to heat water quickly and efficiently, as well as for boiling water for other purposes such as cooking or cleaning. When it comes to picking an inverter for your electric kettle, there are a few things you need to know. First, you need to make sure that the inverter can handle the wattage of your kettle. Second, you need to make sure that you have a battery with enough capacity to run it.
What Inverter for an Electric Kettle?
When choosing an Inverter you need to pick one that has a higher wattage rating than that of your kettle. If you want an electric kettle that boils water quickly, then look for one with high wattage (upwards of 1,500 watts). If you’re more concerned about conserving energy and money, then look for one with low wattage (under 800 watts).
To run a 1500-watt Electric Kettle you’ll need a 2000-watt inverter.
How Long Will a 2000-watt Inverter Run an Electric Kettle
An inverter is a device that converts DC power into AC power. The source of this power is the battery. The battery capacity determines how long you can run the electric kettle.
In order to get the size of the battery you need to get the number of amps the electric kettle will draw and calculate the amp hours needed.
How Many Amps for a 1500-Watt Electric Kettle?
To find the size of the battery, you divide the watts by the voltage.
In the case, you have a 12-volt system, so you divide 1500 Watts by 12V and for the 24V system, you divide by 24V.
1500/12 = 125 Amps
1500/24 = 62.5 Amps
This however does not give you the size of the battery you need but the capacity of the battery reserve that the electric kettle is pulling through your inverter. So you need a battery that you can safely pull 125 amps per for the 12v system and 63 amps per hour for the 24v system.
How Many Amp-Hours for a 1500-watt Electric Kettle?
125 amps is a lot to pull from any system and will require bigger wires and a size able battery bank so it is best to go with a 24v system pulling the 63 amps.
To pull just over 63 amps per hour you’ll need a 24-volt 300Ah LiFePO4 battery bank.
Even with 63 amps drawn from the battery you still have enough capacity to run other high wattage appliances from the battery even an air fryer. Another thing you will mostly likely not be running your electric kettle for over an hour.
What Battery Capacity to Bring Water to a boil
The time it takes to bring water to a boil in an electric kettle depends on how much water you have in it and how high you set the temperature setting on your appliance. For example, if you have a 1-quart capacity kettle and set it to high heat, then it will take approximately 2 minutes for the water to reach boiling point. To use an electric kettle for 2 minutes you’ll just need 50 Watt-hours of energy.
| Length in time | Watts Requirements | Amp-hours (24) |
| 1 hour | 1500 | 300Ah |
| 30 minutes | 750 | 150Ah |
| 15 minutes | 375 | 75Ah |
You can actually use a 50Ah battery with a 2000-watt inverter to boil water using an electric kettle.
