I started to do my own solar instellation at my house " will post some photos of that later". After reading and asking around and burning my fingers, i went for the best stuff i can get my hands on. Then i Decided  that i need to peak in to black hall of lithium back-up storage for my setup but that is a really expansive play ground and even the local guys are really expensive, till eventually founded this guy that's new in the market importing Lifepo4 batteries. 

I decided to go the DIY root. Did a bit of google and in youtube i founded that this diy stuff is massive in the state side.  The local manufacturers use the same sort of sells in there builds and use there own design BMS or one from other manufacturer's. I found some on Alixpress that i'm waiting to arrive.

Placed my order for my 16?120Ah Lifepo4s from this local guy and it was here super fast. It's about 6.2kw of power if you use the full 100%, then cycle life is about 2000 then. If you run say between 90%cycle, then you can get way more cycles.

My plans is to build this ine when my BMS arive and test and build then 1 or 2 more for my solar setup. Here some photos:









600mm x 600mm x 250mm cabinet where everthing will go in




Cinnected them that they all can get to 3.297volts resting. 2 where showing 0.015v lower, but that is fine. To thing connected lile this they more them 1900amps.



At the end it will lool something like this
