My question is: does it make any sense to invert the power at the array and use this ac to make the long run to the batteries THEN connect to a typical battery charger rather than a dc charge controller? Im mostly concerned with huge dc conductors making this run across the property. Havent delved into the specific design enough to size said conductors yet, or specify any equipment, but wanted to know if im barking up the wrong tree ir not.
