Solar energy storage in LiFePO4

[Dacian Todea electrodacus]

Hi, I'm new here this is my first post.
I'm an electrical engineer and live offgrid somewhere in Canada :)
I have already two years of full time OffGrid designed and build my own super efficient house also designed the solar energy storage solution for my house.
I decided to use LiFePO4 for my hose for many reasons but amortization cost was an important one.

Here is my setup and my 7 day energy production and consumption graph you may find interesting.
