I am installing an off grid solar array with a battery bank. my house is in the woods, so I have to put the panels 200 feet from the house (and consequently from the charge controller and batteries) I have 6 300 watt renesola panels. They will be wired 3 in series and 2 in parallel. Planning to use Midnight Mnpv3 DC combiner box near the panels so I can use a slightly smaller wire to the house. How do I calculate how big of wire I need coming from the combiner box to the Charge Controller roughly 200 ft away? I calculated this online some time ago and got AWG-6, but forget how I got there. any help is appreciated!
