Then that's not a LiFePO₄ friendly charger and shouldn't be used with LiFePO₄ batteries. There is no reason to charge a 48V LiFePO₄ battery at 58.4V. 56.0V - 57.6V would be the maximum for daily use.
3.65v max single sell LiFePo4 Voltage x 16 cells = 58.4V
But of course it is true, one should have lower vmax per cell voltage like 3.5V.
Of course we can lower the max charge voltage at the inverter... this will lessen the problem until voltage delta increases...
However this does not solve the issue of BMS disconnecting when one of the cells
reached VMax (now let us say 3.5v) earlier than the rest (which are still lagging at 3.45v).
And even if the battery is perfectly top balanced and well maintained, no way will all cells age equally.
Show me a 1 year old battery were all cells go up and down in perfect unison (within 10mv delta)?
One or more of the cells will degrade and reach threshold regardless how great the BMS' balancer is.
And once a threshold is reached, it will:
By that statement what were you assuming I meant? That the BMS turned off the inverter?
In that statement, it was obvious the system is in the charging phase and not consuming battery juice phase.
"BMS cuts off power" was clearly referring to disconnecting the battery to the Inverter/charger:
I've seen Daly, JBD disconnects the inverter (Deye, Growatt, Victron)
Disconnecting the battery to the charger is a protection
Inverter/charger will still continue to run like a battery-less on-Grid inverter.
The problem is when using Physical Relay BMS like those big JBD or QUCC.
Closing and Opening degrades contacts of the contactor and it is a thing.
Try observing and you will hear the Contactor clicking during the upper part of the charge cycle.
