24 panel Iron Ridge with some extra panels and braces. 42' of 3" galvanized pipe across, had to use it all, too expensive to cut off.
Adding four more (at the bottom) after the original group drops to near 60 percent.
The dual bank shelf is made of repurposed utility pole Cross Arms, approximately 3.5"x4.5" Douglas Fir. Be assured, those 5 unit Current Connected racks are lagged to the back wall too.
1"x½" - 55" copper busbars. The length between the top and bottom battery terminals is 52⅞” so I went with 25% of that to space the cables.
After following this man's thread, I choose the 25% figure as there was no 7 battery example and he mentioned anything was an improvement.
So far after monitoring all 14 batteries with Solar Assistant, they all seem to be nearly the same. The four newest act differently, but do balance.
As of this, the original 10 are at 11 cycles and the other 4 at 8 cycles, so basically the same.
Phase II of PV panels
4 - 4x8 sheets of OSB
IronRidge can be seen through the trees on the right.
Temperature was in the 40s all day and was 46 degrees until 5am, then slowly dropped into low 30s by noon. Forms removed, 2" foam board on top and covered with another foot of dirt to keep from freezing, so it could cure properly.
More parts arriving.
