I need some help to figure out the amps used in the following situation.
I have a hot water heater element on my boat that is 240v 1500 watts. I want to use an inverter on my battery bank ( 360 amps total ) to convert 12V DC to 240v AC. If I do the maths on the amps drawn using the 240v it says 6.8 amps.
So it's all good.
Then I was looking at heater elements that are native 12v 600watts. That maths says 50amps. So that's not good.
So is it correct to do the amp calculation only after the conversion to 240v?
I'm confused.
