Hi I have home office setup using approximately .300Kw according to the UPS display and that with everything but the laser jet running including a desk lamp. Following one of the videos that's like 7200 watts per day and unfortunately due to my job and always being on call I can't turn everything off at most when I am sleeping the system drops down to about .100Kw draw. If I am following the videos right I would need at minimum 24volt system to handle that and definitely want a mppt so it could flip over to utility power when needed what I am trying to figure out now is how many solar panels and what kind of batteries to run with. Any suggestions would be welcome I am leaning toward Fortune 100Ah packs as I love the modular and almost lego like feature.
