Let's see, 2HP, that's 1500watts nominal, or 1.5kW continuous, that's 36 kWh per day, at 48 volts DC thats 720 AHs from the system, so to never fall below 60% SOC, your battery bank needs to be 1800 AH's which means a small fortune in batteries, then there is the panels, to produce 36 kWh you'll need 18 350 watt panels, two masts, and all the fixins.
Let's see if we can do this with less power. OR...
