Dan’s backup power system: Frame 1 is of big white box Xantrex SW4024+. It’s a 4000 watt continuous 10,000 watt surge, 24 vdc (volts direct current) to 120 vac (volts alternative current) Sine Wave inverter with built-in battery charger. Small white box is a step-up transformer to make 240 vac to run water well. Large grey box left of inverter is homemade DC Disconnect panel. Battery bank feeds inverter and propane DC generators feed batteries. Two boxes right of inverter are GenTran Transfer panels.
  Frame 2 is of battery bank, set-up for 24 vdc with 1500 Amp hr of capacity. Batteries don’t need water and don’t vent.
  Frame 3 is of 2 Kohler COM 6, 26 vdc Propane generators that feed battery bank. They’re rated at 6000 watts DC each. Solar panel near each generator keeps starting battery charged.
