Victron Multiplus limiting total output to SOK 48V 100ah server rack battery (16 cell Pylontech BMS) charge limit.
System is off grid with 3kw of Solar and 20Kva Generator for backup. Cerbo running v3.00-22 also tested with v2.93
I have 3x Multiplus-ii 5000 with a set of SOK 48v 100ah batteries commanding a charge rate of 95a (well below the 210a max available from the Multis when charging via generator) that's great, I'm happy with the 95A however when I place a 4kw AC load on the charge rate of the battery goes down to about 1100w or 20a. Still giving a total output of the commanded 95a.
The generator is only running at 25% capacity so it's not a genny issue.
The way I understand is that the Multi s should be providing the 95a in DC to charge plus an additional 4kw to the AC load?
Now, if I remove the load the batteries continue to charge at the low 20a rate. Turn off the Gen and restart full 95a to the batteries again until a load is applied.
Current limit by switch is off on the Cerbo and each Multiplus is set to max charge rate of 70a.
Any ideas why total max output (AC and DC) is limited by BMS charge limit?
