Thanks for the diagram, that is about as I suspected, my problem will be that the + and - are on the same end of the batteries, will make wiring and testing a bit hard. My last battery setup was 14 years ago and I did not pay much attention when I ripped them out for salvage. Y'all talk about 70 MM wire, that is huge. I did use a 20 foot run of 600 MCM, about 28/30 MM , when I was at 12 V, but have been on 4/0, 212 MCM for last 20+ years. My current battery setup is about 10' further away so may add to the 212 MCM, as we are hitting a lot of 3+ KW loads with the new setup but rarely get over 150A at 24 V. I have been off grid for 32 years, if I can be of any help here with the solar end, just let me know. I looked for a message setup but have not located it here. Cheers.

Smileypete's battery layout has been posted about the solar forums. Seems years ago I had a similar layout but for series and parallel. The diagrams here seems to be mostly parallel I wondering if y'all could suggest a best balanced diagram for series and parallel of a 24 Volt system using 8 -- 12 V. batteries. Cheers, and Thanks.
