The solution evolved over a few years from a small 12V system to keep a Fridge and Freezer running for just a few days, to a Powerful DIY Inverter [designed by forum member "wiseguy" with many members, especially "Poida" all contributing to the final Single or Dual power Inverter design]. This runs the entire Home and woodworking workshop completely off grid with no concern for power usage or how many appliances are running at once, all electric including 3.6kW Hot water system, a couple of fridge freezers, Stove, Oven, Air-conditioners, mains pressure water pumps etc, plus huge workshop machinery with startup loads of over 25KW surge, it can easily handle over 13kW of load for long periods, day and night. The posts are a bit of a convoluted read as I tend to go off on tangents, my excuse is I'm getting old Redundancy is 8 x 60A Solar regulators parallel switched, four Low voltage configuration high power panels per Regulator, separately switched parallel banks of high power LiFePO4 batteries, an Inverter built to allow a power module swap in under 10 minutes, fully running and tested spare modules and lastly, a spare smaller Inverter. The system is a nominal 48Vdc system.
