total battery capacity needed.

Solar panels usually don't produce rated power because conditions usually don't match standard test conditions. They can produce more, typically in a clear, cold, high altitude location, but more commonly produce less. This could be because of non-optimal tilt, haze or thin cloud, hot panels, dirt, etc., so having more isn't a bad thing. You could add a second controller if you want to fully use panels, maybe with an opportunity load like water heating.

Except for the pump, all your loads should run nicely on something like a Morningstar 300w pure sine wave inverter. Using an inverter like this keeps tare load (power used just being on or very lightly loaded ) to a reasonable amount. A larger inverter to run the pump might take 30w or so in tare losses, which could add nearly 50% to your daily power use. The big inverter may have a search mode to reduce tare losses, but running the small loads will keep it out of search. One solution would be to get both a large and small inverter, and use the big one just for the pump. 1/3hp isn't a huge pump, so likely can be done on a 12v system. Would need specs though.

2000w daily use is around 160ah. 2 days would be 320ah which would be about 50% state of charge on a 700ah bank, which is about as low as you want to take a lead acid deep cycle battery. L16s are pretty common and can make a 700ah 12v bank without using lots of parallel strings.
