Alright. got the panels now. this guy apparently sells used ones all the time so I can add on if i wanted to that way, but I probably wont. now I need to get batteries and the AIO. Found a local guy who may have some battle born LiFeP 12v 200ah for 700. may get those but it seems a little steep for what im doing. That or some sealed lead acid batteries or something. I don't know yet
Test run with a small system first?

Yeah. i am probably sticking with that PowMR AIO for this set up. may just go ahead and order it. i think that the battery is a little tougher decision for me now.
The best price I can spot on the PowMr 3kW 120vAC, 24vDC, PV-450vDC at the moment is $429.99 for in stock US ship off Ebay https://www.ebay.com/itm/1456250648...-afdf-6e974495c736|iid:1|vlpname:vlp_homepage
You might try offering a bit lower and see if it flies considering there has been recently lower prices for this model.

Kind of a terrible drawing. But it seems like I need to have a 4 AWG wire for the batteries because the charger operates at 80 amps and I need an 8 or 6 AWG wire for the AC output since the absolute max amps is 33. In the sub panel I can connect to either a 25amp breaker or a 30 amp breaker so that it cuts off if is too much of a load draw. Not sure which amp breaker I should choose or if the standard ones you find at home depot are correct for this application or not. Connecting the remaining loads to the breaker panel would just be standard 12 gauge.
Should I have a switch between the batteries and AIO? I am not sure. I have seen some people do it and others not. Would the 15 amp DC switch also serve as an emergency stop? What do I need to do about that? I can't think of any other switches or things that need to be on the wire between each of the 4 components.
Any other tips on keeping it safe are welcome too.

235W x 6 / 28V charging = 50.3A
But discharge:
4000W / .85 efficiency / 20V cutoff = 117.6A
oh. ok. thank yall for catching. I see in the manual now too. its actually 2AWG wire instead of 4AWG and 10 instead of 8. wow. very thick. Holy cow 2 gauge wire expensive.
if i wanted to add more panels, would I have to do it in another string? It seems like that would be the case
looks like i found the same model AIO i'm looking at getting on ebay for $50 less

Be careful when reading specs! The one from Ebay you link to is the low voltage PV model (max 100Voc) with only 60a charge. The one I gave you was the higher PV model 450Voc) and 80a charge and listed at $429.99
They are very similar but the low voltage one will not work with your panels all in series.
Hopefully you have not already ordered.

Oh yeah. I had realized that after I posted it and forgot to edit. I am getting the correct one directly from source.
Still debating what to do with batteries though. I could go for the two $700 for 12v 200ah battle born battery deal. 1.4k for a test system though. I mean I could use them with something still but I don't think I would build a full battery system around battle born batteries. at least at this point I dont see why I would do that.

Battleborn isn't worth the money, you can get the same capacity for a LOT less money elsewhere.
From another thread.
I got something far cheaper. like half as cheap. lol. Everything will all come in over the next week or so and I will build it next week.

Even half as cheap as a Battleborn is still twice as expensive as other decent brands.
Really? what brands are those?
Can I just bring the solar into a standard breaker panel with a standard breaker fuse? My idea, like i have in the drawing above, is to put a 30 amp breaker in a smaller breaker panel and just move the loads I want to test in there.
This is my main electrical panel. It looks a bit messy to me. I also don't think its anywhere close to what is code now. this is probably the original panel installed in the late 60s early 70s. There is no main switch and I can't even tell if its connected to a grounding rod (i think its there but i just dont see it).
I would certainly need to get a whole panel upgrade to add solar and meet code and to even do a critical loads panel or something, if thats worth it for my situation.
I see a heavy bare copper wire that appears to connect to the neutral bus (If it loops up and over under the mess of wires at top) which would make it the NG panel for your home. That bare wire should lead outside your home to the ground rod. Fairly typical electrical panel though it would be better to have a Main Breaker since there is no way to kill it locally for doing work. Is there a Main disconnect out at your pole or anywhere?
Likely you will need a local electrician to explain your options.
ETA: What are those reddish pink small squares on the corner edges of the solar panels? You do not want anything blocking or shading the fronts of the panels.
Doesn't seem like there is a main breaker anywhere. Unless its tucked away in the meter box that I have never tried to open.
they are little foam squares. I will pull them off later. I kind of didn't want to fool with them after lifting all the panels by myself. Almost threw my back doing that, which is bad because I am young (33). lol. They are heavier than i thought they would be together and it was hard setting them just right on the wooden posts i put in the ground.
