Hello Everyone!
First post here, so let me introduce myself quickly. I have been reading lots and lots lately (including some stickies here) on solar power cause I would like to make the plunge and add a little solar power plant on my stationary RV to extend our really short season here in Quebec, Canada. I want to single pick every components of my system so I can have a better quality system for the price I will invest. But even though I have some basic electricity concepts, the number crunching for my inverter choice is leaving me puzzled. I explain:
Lets take a normal AC household appliance that we all know is 1500 watts like a toaster or an air dryer for example. And let's also say it is connected to an inverter. According to the formula, this same toaster consumes around (1500w divided by 115v) 13 amps AC when working. But inside the inverter, on the battery side, how many DC amps is this inverter pulling on the batteries to supply 1500w to the toaster? More because the voltage is lower? Less because of the RMS equivalent? What's the formula I should go with here? Or has anyone actually measured this current with a meter?
It's that I'm desperately trying to make sense of Sunking's sticky on Inverter size VS Batteries size.
A big thanks in advance to all of you that will take their precious time to answer.
