For starters, a 25kwh server rack LFP battery is around $6500 so this may not pencil out right now. Battery prices are falling by around 40% per year so you may want to wait a bit. A quality LFP battery is probably good for 10 years but battery tech is still moving forward rapidly in terms of energy density and cost per kWh. Solar panels are really pretty cheap now so you may want a mixed system for the best energy leverage.

100kwh per day on average sounds like a lot. My house averages around 20kwh per day. Does it make sense to chase efficiency first and follow with a properly sized energy flex system?
