- I am designing a 3-phase 45kVA marine system with 3 parallel 48V/15kVA Quattro's.
- The DC energy storage will be 218kWh at 48V (~4500Ah) while using LFP Batteries.
- My challenge is that I can't decide how the BMS will took place because of the 5 parallel limitation of Victron BMSes. (Data communication limit)
This is a Victron setup in Romania for a furniture factory using 20 pieces of 25,6V/200Ah Victron LFPs for backup energy storage. But I don't see any BMS in the setup, it probably will be managed via existing SCADA.
- Victron Energy - Install Timelapse - Shipping container full of Victron equipment to power a factory: https://www.youtube.com/watch?v=Lj2L8hcCKfs&t=352s
So, the €/kWh cost for LFP is slightly higher in Victron LFPs but this is not the concern. MG Energy LFP280 with a single Master LV will be the most feasible. But, I can only use Victron solutions at the moment.
My question is that how the 5+ pieces of LFP batteries can be managed my Victron BMSes?
Maybe I can parallel multiple VE.Bus BMS V2 together for parallel operation but I don't know how to parallel control Quattro's with multiple BMS setup. Maybe this can be programmed in GX device for such configuration.
Practical suggestions much appreciated, thank you.
