I just purchased 6 x Q.PEAK DUO BLK ML-G10+/t [data sheet] and am a bit confused on what charge controller to get and how to configure them. If I'm reading things correctly, VOC is 45.20, with "at MPP" specs being 37.68V @ 10.48A. Right now I have a tiny 24.8V 150Ah battery and a 3000W inverter which is just my proof of concept setup, but I do have two long range Teslas which will be more than happy to store the energy produced during the day (although, in a highly inefficient manner at the moment thru a DC->120V conversion — end game is split phase 240V, but that's down the line).
Strings are how many are in series right? Most decent charge controllers want 100V+ correct? So 3 in series would would be 113V "at MPP", is this okay to be over (as long as you're not under, I'm assuming)? How would I use all 6? What charge controllers?
Considering that I'm very likely going to 48V as my next battery build, ideally a charge controller that would work at both 24V and 48V would be nice. BUT, if there is something cheap (read: not Victron prices) that will work now for my 24V system, and if y'all recommend the 48V charge controller be a dedicated 48V unit, I will consider something that is 24V only too. Reason I'm thinking this is because sometimes dedicated units (for my future 48V in particular, that is the one I care the most about, and where I will spend top dollar) are much better than units that support dual modes/voltages.
Hit me with some suggestions! I am not opposed to Victron from the getgo. What should I be looking at? What configuration for these panels? This will be ground mount while I play around with things for the time being. Ideally, minimizing wire gauge by doing series vs parallel as much as safely possible would be preferable as I have a longish run and since this is all mostly proof of concept, I don't want to spend a ton on cabling I may not use down the line.
