I discovered the use of 18650 cells a few weeks ago while searching about solar panels setup for my house in south of France.
First I was planning to install a simple grid tied system to sell all the production to our national agency. But due to regulations change (as of Oct 2017) this can not be possible anymore with a DIY setup.
The only way to use a PV setup in a DIY way is to feed the house through a "smart inverter" which pick-up the power from where it is cheaper : 1/ PV, 2/ Batteries 3/ grid.
Looking at batteries I found out that this is a really expensive item on the market going from 0,3/Wh(LeadAcid) up to 2+/Wh (LTO). The Li-Ion seems a good alternative but may be a bit expensive.
I found then the videos from Jehugarcia, then some other and at the end the ones from hbpowerwall.
Glad to enter the DIY world of powerwalls.
Cheers
