Hi all,
I have been contemplating the idea to build a powerwall and so far all I did was buying a couple of 18650 or recycling some without doing anything with them really... Now I just jumped the gun and I bough :
QTY : 3
Type of cells : LiFePO
Manufacturer of the cells : A123
Maker of the pack ( yes i plan to use the pack as a whole ) : BAE Systems ( yes the military corp )
Max discharge current : 70A per cell ( crazy hein! )
Voltage of the pack 40V
Voltage of the cell : 2.3/3.3V
I am still missing a couple of infos but so far that is what I bough.
Here's the link :
https://www.ebay.ca/itm/3-used-test...e=STRK:MEBIDX:IT&_trksid=p2060353.m2749.l2649
So I got a couple of questions :
1- Since I plan to use these pack as is, should i go and use the 3 of them in series to get 120v DC? I think that could be great to lower the cable gage and by doing so the overall cost of this system?
2- This summer I plan to test it and add packs later on...
3- I only have 1 solar panel that is rated at 160W ( Eventually the goal would be to have 10KWh+ solar panel + wind turbine )
4- I am quite good at programming so I am considering an exterior to the house powerwall in an aluminium enclosure with sensors to regulate the humidity and temp lvl of the pack and of the enclosure using pi + arduino.
5- I gonna need some advise regarding the charge controller.
Still in the planning phase, but I am quite excited
