I'm not combining my strings, they go directly to the Inverter. If i do it like the second picture, it will keep my wire runs closer to the same length.Whatever is easiest for you is fine.
I also have 2 strings in parallel. I done mine like the first picture. I ran a single negative to the far end and combined the negatives from the two strings there. And then combined the positives at the close end.

Maybe I misunderstood?2 strings per mppt
Seems like a waste of wire. But maybe you have future plans that require doing this.Inverters have 2 inputs per mppt, thats where they get combined.
That makes sense. I wasn't aware of the #10 limitations.I would have had to up size my wire to #6 to keep the voltage drop down. #8 was getting to close to 3% V loss for my liking.
Unless I'm mistaken, sol-ark 12k pv inputs limit you to #10 wire.
I wonder why some manufacturers do not allow bigger input into an SCC to account for longer runs to help with voltage loss. I had the same limit with my Victron SCCs.I would have had to up size my wire to #6 to keep the voltage drop down. #8 was getting to close to 3% V loss for my liking.
