I'm skeptical this is actually 750W, or that it'll only run for an hour a day, or in that case, that it'll do anything beyond provide lukewarm water. I gave up on hot water planning a 30kWh battery bank, I say go propane.
How many GPM is your pump? Do you have at least 60 times that in water capacity? lol, your estimate is too high.
All of these, use a Kill-a-Watt or other meter and actually measure your weekly usage. Your grinder really runs for an hour?
Yesterday my yield was 1.62kWh. I used about 600Wh (25W load running 24/7) Net yield, ~1kWh. 24/7 loads are the killers.
I went EV lithium/Tesla. Systems with an internal BMS like the battle-borns and others are more or less plug-and-play. Everything else you will be doing it all yourself. If you enjoy tinkering with electrical, go for it. If you don't like watching voltages, or are uncomfortable in the slightest with any of this stuff spend the extra $ on the premade solutions.

Thanks for all the advice and real world numbers. I said in another post I don't have any of this stuff to use a kill a watt meter on to test. Just going by averages I'm finding online. I'm actually glad all my assumptions are high.
You've got a great build. I will get to asking specific questions again in a week or two about your system if you don't mind.
