Hi !
I want to build a 48V system with 16 EVE 280Ah cells, and 1(-2) MPP Solar inverter (5048MK aka Axpert King)
But I want this system as an UPS. So no daily charge and discharge.
I think battery to last long I charge it to 60-70%
I know inverter is stupid. It has only the sum V of the cells and the cells discharge curve is very flat. So it does not know the real SoC of the battery.
I know I need a BMS with shunt to really know the SoC.
Is there a solution where the inverter knows the BMS SoC and I can set the real SoC % to charge the battery ?
So the BMS is connected to MPP inverter ?
Or even BMS controls MPP and tells it when it needs to charge battery ?
