"Anyone who's tried to use a couple hundred foot long extension cord or had to run wire to an outbuilding has experienced how quickly the voltage drop eats up any useful power when you're at double and even triple digit voltages."

Try running 12 DC from the batteries to the inverter.

Paladin’s right - DO NOT run DC any further than you need to. Power your inverter(s) and run everything of AC as you normally would.

Can’t run air conditioners, of course, but lights & refrigeration should be fine. NO COFFEE MAKERS EITHER!
