    Full Off Grid Solar - Design Help Needed

    It looks like the better/later model is the MS4448PAE so I'll go with that. I guess it stacks better or something. I told my wife about what I'm learning here and the idea that we should run more things while the sun is out and batteries are charged to use the extra power we have. She said...

    It is a solar tracker based on data from some database. So the panels move with the sun's angle and such to get maximum solar.

    Full Off Grid Solar - Design Help Needed

    I've been reading quite a lot this evening. You and Boondox seem to give lots of advice out so thank you for all the contribution to the community. I co-run a very large forum in a completely different subject and it's people like you both that make the difference. For my inverter I'm thinking...

    Oh that is something I didn't consider. Thank you! So would it be better to wire the panels at 4x6 instead? That would yield 150.4v and 49.62a instead right? I might be smart to go with the Victron 250/100 for an extra $200 to have a little more upgradability.

    Thank you so much boondox for explaining that. I think that generator should be good for my needs initially but I'll make the final decision once the rest of the pieces and parts are selected. So now going to the charge controller, I was looking at the Victron 250/70. I'm thinking of Victron...

    So with 56qty 100ah batteries I'll have 5600ah if I wire them at 24v or 48v then? I'm fine with 48v then no problem. What about the solar panels then? Do I wire those at 48v as well then to match the battery bank voltage or will the charge controller manage that? Also is this generator a...

    I'm not sure I see the advantage of going to 48v. Wouldn't I have to buy double the batteries? FYI the maximum watts we would pull at any given time would be 1300 continuous with 1500 startup if we are turning on the mini split. For instance we wouldn't have the AC/heater on and vacuum at same...

    So 24 panels but do I have to double that since I'm wiring my batteries at 24v so I need to feed them 24v or does the MPPT charge controller figure all that out? The cheapest LiFePO4 12V 100ah batter I could find was around $450 where the AGM is $200. Am I a bad shopper? Lol

    So 11kw of PV. From what I have read this is what I'm figuring. Tell me if I'm doing this wrong please. 190 watt panel * 4hrs * .8 = 600 watts from each panel. 11,000/600 = 18 panels. Wait, I'm 24v so that means I need 36 panels? The batteries I'll be using are AGM. I know they aren't the best...

    First post here. Sorry for not being a contributor before asking for help. If there is an Amazon referral link for this forum or a donation page, I'll be more than happy to give back. I'm designing/building my primary residence in E. Washington state. 16ac of very secluded land. No power...
