If I were building it,8 AWG wire will limit the panels to 40 amps.Yeah, no permit or inspection, but I do want to do it correctly.
8 awg, definitely isn't large enough for the panels I have
Yeah I only have between 60 and 115v to play with as far as the working voltage goes. So that's why I'm at 2s6p to try to make it stay within requirements.If I were building it,8 AWG wire will limit the panels to 40 amps.View attachment 123720
And if you derate that by 1.25, That would leave me with 4s3p. Probably would be too much voltage.
I dislike these games.
Why yes, yes I did, technodave. Pew. I, I, I.did you read the whole thread? I did!

Limit? No.If I were building it,8 AWG wire will limit the panels to 40 amps.
NoSo if I go with 4awg, can I pull a few threads off the connection to get it to fit the 6awg input on the 3080?
I’m considering a 6048 for a project. I think if paneling becomes a problem putting the puzzle of voltage and amperage and wire size, I will hook an SCC to charge from the panels that don’t fit into the all in one.Yeah I only have between 60 and 115v to play with as far as the working voltage goes.

You may build it to what you want. I only hope you do not live next door or park by me.imit? No.
Read your own chart. 1sr column is not THHW.
My example... 7.81 imp *6 = 46.86 amps *1.25 = 58.575.. Array is split in half AND used panels soooo never see that current. Using my linked chart, awg 8 good to 70 amps, using your chart good to 55 amps. So, good

I need to read the manual a little more and check the forums to see what happens when others do this.So you'd have a charge controller and the AIO hooked to the same battery? Do you have to do anything , or put anything in between the connections?
(Sorry, I'm a rookie...)
Sure. Circuit breakers on both sides of a device provides a quick, simple way to completely isolate that device from electricity. Maintenance, upgrades, troubleshooting...So you'd have a charge controller and the AIO hooked to the same battery? Do you have to do anything , or put anything in between the connections?

My opinion is that 4 gauge is overkill and unnecessary. But if you're determined to use that perhaps you can add ferrules to the ends. That might help. Get a good crimper.So any advice on linking the 4awg into the 6awg ports on the 3048?
I also have a 100 amp dc circuit breaker left over from another project. Any issue using that in between the combiner box, and the mpp unit?
So an 80 amp? I'm at 60 amps with no issues...Provided that i it is a DC breaker...
As a simple switch, no issue. But if you have an overcurrent episode, that breaker is too large.
