so I get the whole solar panel charges battery. battery powers inverter thing.
so lets say I have an 8kw system (using a big number for a reason), I get a 6kw inverter. (want extra 2kw to charge batteries, charge controller to suit this model is there for this example)
so I KNOW that you can get 8kw systems. I KNOW you get 6KW inverters from 12volt source.
so the question is why is 200 amps the wire I see on most of these off grid installs?
if, lets go both ways here, the 8kw solar panels are charging batteries then the wire will need to be rated for 8000w/12 which is over 600 amps. I understand that each panel is giving small amps each so this could account for that.
HOWEVER a 6kw inverter is 6000/12 or 500amps..... and that only has 2 wires in..... how do these systems not fry???
