    Largely because 12V requires larger conductors, and because well pumps are relatively high draw power users. Since you are going to have a mix of AC and DC, put the well pump on 120VAC instead.

    Buck transformer. I'd never heard that term until reading Cruisin Sloth's post. I looked it up. Interesting.

    You may want to look at grundfous pumps.
    They have one pumperson that will run off pretty much any voltage up to 300v AC or DC. But I don't think it will run off standard 12vdc power. I think it needed 24 or 30 volts minimum.

    12v systems and gear are super common but suffer really badly from voltage drop. A 1 or 2 volt drop in a 12v system is really bad like the difference between stuff working or not. A 1 or 2 volt drop is not nearly as detrimental to a 24v system and a 2v drop is negligible in a 48v system.

    I've been considering a Grundfos pump for awhile now, and in fact I spent some time on line today looking at this one. It requires 115V AC, which is fine for my situation.

    photo-3. You NEED to Learn IER or Power , & the Basic of a harvest .
    You are caught in a LIE of lost . Learn POWER and the formula of the build . We are at a set of set formulas .Voltage drop as has been mentioned ,
    you need to harvest more that you can use in 2 days use .and store 3 days use is just a break even system..

    Just that pump you posted is needing a 3000w plus inverter . or something will burn out.
