I am planning on building an off grid home this coming June and have been looking in to solar power recently. I am not incredibly knowledgeable so when I watch videos from evtv (or anywhere for that matter) I am lost after about 10 seconds. I understand basics, I just dont know what is needed to interface everything together. Is there a laymans guide somewhere you can point me to? One without a guy saying You need to remember the EVS and the BBAMT and the whatever other acronym exists that I have no idea what it means.
Basically I want to build a powerwall using the Tesla modules out of a Model S such as this
https://www.ebay.com/itm/Tesla-Mode...m2ac6e33656:g:1~sAAOSwFAtcQm0g&frcectupt=true
I am confused about a few things.
1) The controller I need to buy must be able to interface with the Tesla built in BMS right? The only ones I could find
http://store.evtv.me/proddetail.php?prod=esp32bms $2495
or
http://store.evtv.me/proddetail.php?prod=basicsmodulecontroller $1295
Whats the difference between these? They seem kind of pricey just for a controller but I could be wrong. Also, does DC from the solar panels enter through the controller? If not, how do you connect the panels to the batteries?
2) Coolant. I don't see any type of coolant system available for these modules. Any recommendations? Does the coolant systems (IE Chiller) connect to a controller so it knows when to turn on and off?
3) Inverter. Again from evtv I can find this
http://store.evtv.me/proddetail.php?prod=12kw $2195
Do I really need to buy an inverter specifically made for these Tesla modules?
Maybe I am mistaken but I thought it would be price beneficial to DIY vs buying a Tesla Powerwall (even though you have to wait forever to get one).
From what I can see an absolute minimum ill need
1) Module - $1300 Each for 5Kwh
2) Controller - $2495
3) Coolant System - $?
4) Inverter - $2195
Total: $5990 plus coolant
$1198 per KWH
Maybe the price per Kwh becomes cheaper for bigger systems? IE, using 10 Modules instead of 1?
Any help would be greatly appreciated.
