Hi,
I finally got my build started and decided to either go big or go home.This is after I installed a 2.4kW Pylontech battery and Goodwe inverter for the prettiest penny in my pocket! having "supervised" the installation of the solar system I told my inner self "that isn't too hard..."So I started off with a 24V system with 1120 cells on a 7S 160 configuration which I kept running for a few months before I found a secondhand Goodweinverter.
with another 14S 80P pack ready i scaled up to a 48V system andcurrently have 2240 cells in service in a 14S 160P setup.
This system has been primarily servicing light loads (lights only) as I monitored temperature, balancing of the packs as well as the voltage sag. It has gone pretty well so far...no explosions, no fires so a few more critical loads have been added on to the DB and so far life is good.
The initial setup wasn't the tidiest (and it hasn't improved much) but the plan to improve it is slowly coming together. So I currently have a Chinese 14S BMS running with this pack and it seems for now to be up to the job. I have my eye on a batrium system but the cost is a bit of a hurdle soit will wait a while longer.
My goal is a 50kWh power wall and hopefully to learn faster than I am building at the moment! I am using an old sever cabinet as my box and haven't used thespace efficiently in it but now hope to slowly fix that by building my new 14S 80P packs so that they can snugly fit into the cabinet. I am considering building sliding shelving so as to make maintenance and upgrading/adding to the powerwall easier, but time will tell whether my welding skills are up to the job.
