SOL-ARK 15K is so pretty

[niktak11]

Why? The Sol-Ark only puts out 160 amps per connection, so at 125%, that's 200 amps, of which the breakers are. Most of the cable I've seen is good for 300 amps at 10 feet for 2/0.

My battery busbars are 15ft away from the inverter battery terminals

I used two pairs of 2/0. Kinda wish I went with 3/0 or 4/0 though.

You moving that much current in/out of batteries?

Dual 2/0 should carry anything you can produce..

Even @ 15ft should carry over 300.

Do you mind telling me what is going on with the MPPT inputs? I've been wondering why there appear to be 12 connectors for 3 inputs, and the manual shows MPPT1+ into connector 1, MPPT1- into 3, 2+ into 5, 2- into 7, 3+ into 9, and 3- into 11. So the even connectors aren't used. My best guess would be that you have 2 serial strings and mounting them together (as you appear to do) makes it a parallel circuit? Guessing, but I'm wondering what is going on, here.

You have 3 mppts. Each can take 2 strings, so that's 4 wires per mppt. So yes, if you hook both strings to one mppt, it will show as one string. At this point, I only have one of my 3 sets of 14 installed, and I chose to run 2 strings of 7. So I ran them to separate mppts to see what each string is doing. Once I install my other 2 sets of 14, I will have to move those 2 strings to one mppt.

lol, I used 4/0 on the grid and load. I can't even find a ferrule that big. ?
I used 2-2-4 on the gen(ac-coupled PV). I did not put on ferrules. I have no intention of undoing the connection.

I used 8 awg for my PV lines, but the input on the PV indicates 10 awg. I think had I put ferrules on the 8 awg it would be too big.

So 8 AWG works on the PV inputs? I have to run 8 AWG because my panels are far away from the house, so I was going to use something (set of IMO Disconnects?) to transition from 8 AWG down to 10 AWG near the 15K. If I can run 8 AWG straight in, it could save me some cost.

I fit 8AWG THHN in mine without issue
