Running a hot water kettle on solar power inverter in Cade's Cove.

by Chad Whitney

We love our coffee. We also love the simplicity of an electric hot water kettle.

Running the electric hot water kettle uses a lot more energy than most people think. I wanted to show everyone how much power it takes to heat water using this method.

Plugging in the hot water tank into the back of our Sprinter van is easy. We will let our solar and battery system do all the work. It does a great job, but it really drains our battery bank.

Take a look at the DC load the hot water kettle draws from our battery bank. Our Go Power 2000 Inverter Charger shows the real time DC drain when running items on our batteries. As you can see we are draining 148.5Amps to heat our water. 

It takes about 15 minutes to heat, but when our battery is low from over use, we needed to head out into the sun. While this is a big load, it is only temporary and we decided we didn't care because hot coffee is alright by us. It was too shady at our National Park campsite in Cade's Cove. No worries, a little drive into the sun will let our 320 Watts of solar charge the battery back up in no time.
