I have a set of 12V, 400AH LiFePO4 ABS batteries connected in series to produce a 24V system. I am charging the system with a MPPT 100 | 50 from a set of 48V panels which can provide up to 900W. The BMS is configured correctly for the voltage of two of these batteries in series. Unfortunately, the battery system is not charging, and I suspect it is due to the BMS' on the batteries.
I would like to implement a dual-bank system fed from the MPPT. I could install two MPPTs, but I would prefer to collect one set of measurements for the whole system, so am looking at installing two DC-DC converters (or 12V-12V chargers), wiring up the isolated chargers to each battery, and setting the MPPT to charge in 12V Li mode.
Just wondering if there are any clean "Victron" solutions to achieve this. I'm looking at using a set of Orion isolated 12V-12V converters. Would a second MPPT be more advisable?
