Hello,
I've read several posts on BMS's and battery options and this is where I think I'm going to start. Any constructive feedback would be appreciated. I’m going with a battery backup for now and plan to incorporate solar panels at some point in the future. My home is already wired with a manual transfer switch where I plug in my gas generator and the battery backup will offer another (quieter) option when the power goes out.
I’m going a 48V DIY approach because I like to know the ins and outs of how things work. You know, so when it breaks on a Saturday night you know how to fix it.
DIY purchase list:
Qty 1 - EG4 12000XP 48V Split Phase Off-Grid Inverter - Constant Current.com
Qty 32 - EVE LF280K V3 Grade A Cells - 3.2V LiFePO4 280Ah Battery $72 each 18650batterystore.com
Qty 2 - JBD Smart BMS 16S 100A 48V Lithium Battery PCB Can’t find in stock???
I decided to go with the JBD BMS based on several positive posts, but I’m not sure which model to go with for a 48V 280ah set up. Does the charging current matter other than charging faster? Like would a 60amp BMS work basically the same as a 200amp version? I don’t think that it would change anything other than the charge time and the size of the charger I can attach to it. But I thought I’d ask…
Also where’s the best place to buy hookup wire? Connectors and crimpers too? I’d like to build my own cables for something like this.
Any vendors to stay away from?
Thank You
