Working to get off-grid: Presently we have 12 panels (awaiting more) which are connected to one of our two mppt 60amp charge controllers. They are 12v panels connected in series to 48v. The other charge controller has only one 100w 12v panel feeding it at this time (awaiting more panels). The battery bank is split. We have one bank of 18-6v batteries holding 210ah and connected in series to 12v and parallel for the duration. The wind generator is just a test model and is completely wrong for this present area of only 5-10mph winds.
