Can a Solar Generator Run an Electric Kettle

An electric kettle is an important appliance in your home as you can boil water for your coffee and even for drinking. While the electric kettle is a high-wattage appliance that consumes a lot of power you don’t need to run it for long periods of time. 

The amount of power an electric kettle uses depends on the size of the kettle and the type of heating element.  The bigger the kettle, the more water it can hold and the longer it takes to heat up. The larger the kettle, the more energy it uses, and a heating element that heats up quickly uses less energy than one that takes longer to reach boiling point.

If you want an electric kettle that boils water quickly and then looks for one with high wattage of around 1500 Watts you can opt for a low-wattage kettle but it will take longer.  

In this article, we take you through how to choose a solar generator to run high-wattage appliances like an electric kettle and how long you can run them for. 

What Size Solar Generator to Power an Electric Kettle 

So what size solar generator for a 1500-watt electric kettle? To size the solar generator You’ll need to match the inverter rating of the solar generator to the power rating of the appliance. The Inverter rating should be higher than the power rating of the electric kettle. So for a 1500-watt electric kettle, you’ll need a 2000-watt solar generator. 

While the inverter rating determines if the solar generator can run your electric kettle how long and how often you use your kettle will be determined by the capacity or watt-hour rating. 

How Long Will a 2000-Watt Solar Generator Run a 1500-Watt Electric Kettle?

When you are determining how much energy a device uses, you must consider the amount of time that it will be used. A Watt-hour is a product of multiplying a device’s wattage by its run time in hours. To calculate Watt-Hours you multiply the Wattage of the device or appliance and multiply by the number of hours you use the device. 

Watt-Hours = Watts X Hours 

To run a 1500-watt electric kettle for an hour you’ll need 1500-watt hours. 

However, you won’t be running the electric kettle for an hour as 4 minutes is enough to bring the water to a boil. 

For 4 minutes you’ll need 

1500 x (4/60) 

= 100 Watt-hours

Running Time = Solar Generator Watt-hours/operating power of the device 

For example to get the running time for a 1500-watt electric kettle

= (1600*0.85)/1500 

= 0.90 hrs

2000 Watt-hours is enough to run the electric kettle for around 54 minutes.  This is enough to use the electric kettle over 18 times. 

How Long Will the Solar Generator Last with a Solar Panel?

 A 600-watt Solar panel can charge the battery in around four hours. This will depend on the availability of sunlight. 4 hours of sunlight in an ideal situation should provide 2400Wh enough to recharge the solar generator. 

The extra 600 watts adds to the run time for the electric kettle. 

With 600 watts available:

= (600*0.85)/1500 

= 0.34 hrs

The electric kettle can now run an additional 20 minutes with the solar generator hooked on the solar panel. This brings the total to 1 hr and 14 minutes. Since you are not running your electric kettle all the time this means you can run several other appliances with the solar generator. 


An electric kettle is a high-wattage appliance that uses a lot of power. However, you don’t need that much power to boil your water even for several times a day. A 2000-watt solar generator can provide enough power to run your electric kettle plus other appliances as well in the course of a day or even night.
