Hi@all,
sorry for my poor english skillsI'm from Germany.
Today, after month of reading, watching, colecting an testing, I've started some prototyping my first power pack.
But at first. Thank you to this great community that has first impressed me and then inspired me to start my own project.
The PV
Off Grid 4*175W and 16*185W(3.6kwp) with room for another 9 Panels.
The Inverter
PIP4048GE
The Plan
I've some small 2HE19" Cases in Stock
For a 48V System I plan to build a 30p14s Setup.
2 drilled 2*2,5mm copper busbars, XT-60 connections for each block and kapton tape for insulation from the steelcase.
All in all I plan to build 5to 6 19" batteries. And put them in a rack in my garage.
Questions
I still have no idea about the bms/balancer..
Each batterie should have about 3kwh.
Of course Batrium is a great BMS but with 84 Longmons it is a little bit expensive.
But what about connecting all blocks parallel before I put them in series to balance them and balancing them monthly again.
If this is enough, I will go for a china smart bms und build an external balancing unit and connect on demand to the batterie that have to be balanced.
Did someone try this before with recycled cells?
Every tip and best practices are welcome.
