I am putting together a system to permanently power essential systems (well pump, refrigerator, freezer) My problem is that my well pump is a 2 wire with high startup loads, I need around 5kw surge capacity and pure sine wave (explicit manufacturer warning). I have a 2500/5000 12v inverter and 4 12v 125 ah deep cycle batteries. I have measured the amperage when the well pump is running at 12.5 A. Thats about 30A out of the batteries for roughly 30 seconds around 24 times per day. The other draws are relatively low in comparison. I could set it up as a 24v system, but pure sine wave inverters in that range are wll over $1000 (I'm assuming that the $400 chineese models on Amazon are junk?). Will this setup work? Or will it ruin my batteries and justify the purchase of the 24v inverter? I could also buy more batteries, but if I have to spend the money I think I would rather spend it on the inverter.
