So since my first installation in spring of 2022 with 3 pcs. Growatt SPF-5000 ES and premade batteries with 35mm2 DC cables the system has been enlarged in several steps. This is a 3-phase setup.
Firstly as the Growatts (5kw each) started taking each other out with fires and literal explosions inside from 28.12.22 they were replaced with Deye (Sol Ark) 8kWs 3 pieces. Same 3-phase setup.
Also in spring of 2023 I expanded the battery bank with 2 more 15S 280AH batteries. So now running 1360AH total in 6 batteries.
Was made aware of issues from other manufacturers of placing the premade batteries pointing straight up instead of flat mounted. This makes the cells lying flat and a possibility of leaking fluid from the valves. The MfG was the one saying the packs should point upwards...
I agree that it is always a good idea with a battery to have the valves point up. This is 4 pcs. of a big 200AH battery type.

So looked into what was available in 19" rack system that could be used for this. Not much available used here.
And the ones solid enough to take the weight was expensive.
So, wood it is. 2x4 technology at its finest ^^
