I finally got some time to start planning out my Fiat powerwall project. Still a but unsure if I am going to just bolt all of these things to my wall, or if I should put them into a half height server cabinet but the wall is my preference to keep it out of the way.
Planning Design / System Details:
24+ kWh of modules
A nice site to see all of them but my system isn'tgoing to use all the cells... I actually don't need all that capacity but I will most likely cut that in half and use about 12 kWh bolted to the wall.
Can't wait to wire this stuff up... it should be super simple but I have some ideas to really make the wiring clean. Still waiting on parts / crimp connectors but these things bundle up pretty nice.
I did abandon my 18650 collection and testing because it was very time consuming I wasnt getting good cells all the time and the quality and consistency didnt really leave me feeling good about the project long term. These cells test very well, all the same, good consistency, and in comparison to packaging the 18650 cells into modules, soo much less work. Even it wasnt the cost of the cells, it was the time and cost of building which made these a much better value.
I still have a bunch of 18650 cells, I will probably sell most bty keep some for smaller projects. I did get some very good modem packs from Alarmhookup (2600 mah LG), but my crown jewel find was the medical pack 2900 mah Panasonics which I got hundreds of. I will most likely build a smaller 24v Powerwall with the PCB for a portable project, but that will be another thread.
Planning Design / System Details:
- 15s / 48v System
- Victron MPPT
- Victron Inverter
- Bluetooth BMS
