Very nice build Domingos. Must have taken quite some time to get it looking that well done. Can you post some more information about your build? Perhaps make a thread in the DIY Battery Project Builds section

Welcome to SecondLifeStorage. I just ask to please use English as this is a global platform. :)

It looks like you have only 15 cells in series?
For "48V" nominal systems with LiFePo4 cells, usually people use 16s for best voltage range.

Nice setup! Would you care to share the high level setup info?
- How large is the battery bank?
- What amount of power can you produce / are these MPP Units in parallel?
- Do you have PV?, what size?
- What are you goals?

Looks very good Domingo, congrats! Very professional, I like the project you made :love:

I was wondering what that small box does with the green connector. If it carries current more than 10 ampere do check the rating, I had some of those green connectors melt with a lot of smoke and nearly fire! :cautious:

Ficou muito bom Domingo, parabéns! Muito profissional, gostei do projeto que você fez:amor:

Eu queria saber o que essa pequena caixa faz com o conector verde. Se ele carrega corrente superior a 10 amperes , verifique a classificação, eu fiz alguns desses conectores verdes derreterem com muita fumaça e quase fogo! :cauteloso:

suporta até 200 amperes mas tem que ser instalada uma peça para medir os amperes, você encontra no ebay, amp 200 amp DC
