Dennis' 14s200p x 2.
#1
Hello guys...

25-01-19
All cells tested. Starting to design my packs. My minimum cell voltage will be 3,25v and max is 4,09v. Batrium setting will be at 4,1v. The average is then 3,67v which result in 50,5kW powerwall.

The build will be in a rack (Check pictures). I got the ABB S5N from US. Pretty good deal, so I can shut down the batteries, just as an extra precaution. 

Anyways, here is some pictures of the progress. 

Shelf's for my battery packs: Will be mounted in a rack (Like Average Joe, but higher) The 30x30mm are aluminum. The shelf is from Legrand, and is a metal sheet made for cables mounted on a wall. The aluminum i got from Motedis. German site, also in english. Good fellow.



This is how my battery packs will look like. 7x6mm2 wire in each Anderson plug. Let's do some math. 6mm2 is equivalent of 9/10 gauge. Let's say 10, just to be sure. When you put that into the gauge Calculator it equals 5 gauge. So the two rows on the side of the batteri is 5 gauge (16.8mm2) and the three middle once are 7 gauge (10.6mm2) 

5 gauge / 16,8mm2 can do 79A.
7 gauge / 10,6mm2 can do 60A.

So the Anderson is rated for 175A, but I use one for plus side and one for minus side. I've found some cheap 35mm2 high flex cable. Which I use for my first 2 14s. Så if I expand to 3 x 14s i will go down in mm2 and in plugs. Because I will limit the power to each pack to 65-70A (Approx) Also went with another design, check that out further down.
