If you have the overkill solar BMS then no problem. They will replace it even if you fried it. Once you get it connected up to the load, then the App should show you if everything is working.
48v system check my work please?

Hey guys, I'm back with another question (thanks to everyone reading these, I appreciate it and I'm sorry for soooo many).
The instructions call for a 4 AWG size cable for ac output, but the cables are twice the size of the connectors, am I missing something?

Your image looks like aluminum wire and not 4 awg copper. More like 2/0 aluminum at that. Unless you simply have to I would avoid ever using aluminum wire in your setup. If you do use aluminum you likely will need a reducing connector between it and your terminals.

I checked before I posted, it's 4, but I could not find copper in that Guage. This was literally the only thing lowes had in 4. I'll see if I can find an electrical place that has all copper. Will the copper 4 awg be smaller than the 4 awg aluminum or will I be at the same inpass with better wire lol?

If you read the markings on that cable it shows 4/0* (0000awg) which is even bigger than my guess. 4 awg copper is much smaller but in aluminum you need larger wire size for the same amperage of copper wire.
You likely need to order the 4 awg online.
* wire size goes up as the awg gets smaller 16 awg is smaller than 12 awg is smaller than 0 awg is smaller than 2/0 awg and so forth.

I think I remember what happened (I did not know what/0 meant but I did understand the normal gages without the /0, i also bought these about 5 months ago lol). I told the man I needed a 2/0 gage for my battery and a 4 for my line out. He must have thought I meant 4/0 and sold me this three line stuff cause it's got 1 2/0 and 2 4/0s. I'll order them online, thanks for putting the 0000awg, it finally clicked with that.
