I am of the understanding every SC module, commonly have individual CMS circuit boards.
CMS is the same as BMS, and should come with each SC Module, I believe each cell has a Voltage Diode.
Well the SC modules I’ve been using are only 16V, the Vehicle’s systems Rail Voltage are 12V & 24V, some with Failing LAB for Testing.
However, commonly most Residential Energy Storage systems are 48VDC, where a SC module would be approx. 52VDC.

From our Tests when Charging a Mixed Systems;
The SC Module will/should Charge First, then from what I understand, as the SC Cells reach 2.7V, the CMS Cell Diodes Stop a Charge going to that Cell, SC Modules are commonly a slightly higher Voltage.
Discharging a SC Module’s GREATEST aspect is 100% DOD with NO Damage, and said 30’000+ Cycle life!
I have found SC Energy Storage # long term = Month+, being very good, as Energy Storage in Not really about Long term storage, it is about Consumption on a Daily basis & during extended bad weather.
(#) If SC module is wired to a Failing Battery/System that drop’s down less than the Set Voltage when Not charged, the SC module will safely sacrifice it’s energy in an attempt to Charge the Failing Battery Cell/System.
So, Why should be an issue with Charge Voltages ?
SC appear Happy to be Punch Charged with High Amps or Trickle charged to the Buss-Bars Rail Voltage.
As for the Inverter, is it not the Inverter that instigates the BMS Voltage Settings of say 48VDC etc.?
Am I missing something, becides a few grey cells
