So I'm thinking about buying some aquion S stacks to replace my slowly dying Lead Acids.
Current Setup is 3600w in panels. Outback controller and inverter. and 12 batteries: 12V - 190amp/h - cheap mexican brand LTH. Hard to find good quality gear down here. 4 in series to make 48V and connected in parallel to make 570 amp/hours.
The aquion S stack is 1200 usd and only 43 amp hours. Max amp output is 17amps and max continuous watts is 680. per battery. So i would need like 4 connected in parallel just to run one of my larger powertools (air compressor or water pump).
I would need like 12 S'stacks to get close to my current amp/hour of 570. Making for a cost of like 15,000 usd.
They just seam incredibly expensive for the amount of energy they store. Besides the deep discharge and high number of cycles, is there something that i'm missing here for which makes the batteries worth it? Anybody have an off the grid setup with them and can share their experiences
