I've got a system with a perfectly working BYD B-BOX 10.0 set of 10kWh (4 modules in a case).
I'd like to expand the system-capacity to 15kWh or even 20kWh but these typical modules are not produced by BYD anymore :-(
I know that BYD produces some units on demand every now and then, but then the modules are quite expensive and I don't know of anyone having the same "expansion-problem" willing to part with their 10kWh set ;-).
If someone does know of such a system, I'm interested in acquiring 5 or 10kWh (depending on the price ofcourse ;-)).
So I'm looking for an alternative solution that maybe one of you have explored and tried and maybe even have in use...
Is there someone out there, that has "mixed" different brands of LiFePO4-sets in parallel, (with their own BMS'es) in one system?
In a way that both sets are seen by a Cerbo and the charging somewhat controlled by it?
As the charging-voltage of LiFePO4-sets is often "comparable", it could be possible to read out the two different BMS'es in the Cerbo and take action to the charging MPPT's if needed and maybe not keep both sets at 100%, but maybe one at 100% and the other at 95% or so.
