Hi All,
Newbie and first time poster here. I know a bunch of the LG ESS 189AH 48V batteries were sold, but I haven't seen many people posted about them. I know w0ss on this forum is working on one. Has anyone had luck communicating with the LG BMS? How are these batteires being deployed, please share!.
My plan:
Fully Off Grid system in my garage for charging my 30kwh Nissan Leaf (just bought a 2016 SL with 37k miles and 85% battery capacity for 11k. Great deal in my book. I just use primarily for intercity commuting.)
I can fit up to 12 - 60 cell panels on the roof of my garage. So figuring 300watt panels I can have up to a 3.6kw array.
The LG ESS is 9.8 kwh nominal. I would like to charge my leaf during the day when sun is out when possible from panels, but I get home when it is dark most days, so will have to charge the leaf off of the LG battery.
The MPP inverter/chargers look pretty good for this application. I can charge LEAF at 110v or 220v, I guess 220 would be ideal for speed but 110 would preserve Leaf batteries longer.
Questions:
1) Best way to connect LG ESS to BMS and then to inverter/charger.
2) Best inverter/charger setup for this application.
3) If grid ever does go down in my house I would run extension cord from garage to plug in critical load such as my refrigerator.
4) Other things I should consider?
Thanks all!
