The customer has purchased 2 x 24 volt 10Kw lithium battery banks
and he wants two separate banks connected to the 2 x 24v 8000va Quattros
and 2 x 250 volt 85 amp smart solar mppts with 2kw of panels on each
these 2 quattros are connected in parallel and they both will be connected to a common battery bus, that has both battery banks connected to that same bus
Now I am wanting to install a VE BMS on each bank these will control the inverters and will have a alarm trigger by the faulty bank as well.
Plus generator autostart is being installed through a CCGX unit
so far all is ok
However how do I do this connection to the VE BUS ????? just install the 2 bms in series so that each will control the inverters if a fault occurs in the LV and HV cell bms units. (will this work)
IE switching off the inverters if a fault occurs in any one bank with LV or turning off the chargers if a HV occurs in any one bank.
the big question is this possible, I suspect Not
any advice out there please on the 2 x VE BMS connections, possible or not,
if it cant be done and its maybe a better option anyway, ill just use the ve bms units to turn a large relay off on each bank thus isolating that bank only. this is the way I am leaning.
but I am interested if this is possible as well
