Hello guys!
I am the happy owner of a QUCC BMS 500A, 4 contactors, 2 pre/dis/charge resistors and hall sensor - the full package from QUCC . This BMS has distinct charge and discharge contactors, and on each of them it can do pre-charge or pre-discharge with additional contactors and an resistor (50R, 100w). It looked simple when I ordered, but now I am trying to figure out how to connect it in an efficient way to the hybrid inverter, that does charge/discharge on the same port.
So, for short, my battery bank will be a 16S2P setup with 32x 302A CATL LiFePo, resulting (hopefully) a 48V ~600A bank. My inverter is an DEYE SUN-12K-SG04LP3, 12KW 3P; I plan to not discharge more than 200A, and charge with less, let's say 100A, but this is not extremely important now.
On their Aliexpress product page, they show multiple connection methods: https://www.aliexpress.com/item/1005002859512726.html?spm=a2g0s.12269583.0.0.721673bdhS9yIN
What should be the best connection method and schematic btw the BMS/contactors/inverter ?
They also list some MD* diodes or diode modules (MDC, MDK), 50-350A/1600V ; my fear is that such diodes will have a significand voltage drop and impact the performance of the system.
Any advice is welcomed....
Thanks,
