So my father in-law is a farmer. He irrigates his field via a 20hp continues pump (220v 49.4amp this doesntd equal 20hp but it's what the faceplate says).
He was impressed with my efforts for a diy solar / powerwall and asked me what would it take to run his pump. I asked him how often he would want to run it and he said anywhere between 8-24 hrs a day.
So because I like challenges I tried to crunch the numbers. I wanted y'all'sinsight to the potential obstacles with this hypothetical system.
Run time: 8hrs
Power Consumption: 220v @ 49.4A = 10.868kw/hr x 8hr = 86.944 kwh
Powerbank: 104kwh storage. W/ 20% extra capacity.
Solar Panels: 18.969kw system with 5.5 sun hours.
Run time: 24hrs
Power consumption: 260.83kwh
Powerbank: 312.99kwh
Solar Panel: 56.91kw system
Inverter: ? I found a few 20-60kw 48v to220v inverter /mppt combo units but I'm not at all familiar with equipment of this size.
Has anyone attempted something of this size?
And what are the potential problems that could arise from a system of this size.
