i do not find where i can disable the " external control" , because i only use my bms as a last protection , victron must be the boss all the time…
what are the parameters to get SCS status Enabled?
already i have controlling BMS = no BMS ( as you can see on picture )
@guystewart is it possible to give me the conditions that must be met for the SCS status to become enabled?
i can not find a setting that is wrong, my thinking is something in the ESS ( VE.config ), but not sure?
After you disabled BMS control. Did you restart the whole system?
Have you tried to see if the old GUI allows you to change it?
hello @nickdb
tests i have done on my working system ( KG - vijver ) :
ve.config : tab charger : removed the Lithuim batteries option
Assistants : changed from lifepo4 to lead acid.
restarted everything , cerbo , MP
never will this SCS option be seen enabled.
restarted the Multiplus several times
on my system KG-Home :
thats a 3 phase system ( now test running )
without a battery ( only a 56v charger- emulating a battery )
changed ve.config like i did with other system = no luck
on this system there is not even a bms connected , and i have never put that option on.
did reboot everything = no change.
if you want you can login to my systems.
old GUI is the same problem.
ok, i did some more testing,
on my working installation ( KG-vijver ) and on my 3 phase test sytem ( KG-home = no BMS connected )
For the love of god, i do not get the SCS status to be active. (always shows Disabled ( external )
test on both system the same =
reset from everything on the inverters , for that i mean, a blank VEconfig file , meaning = nothing selected fom Lithium batteries and no Assistant programmed
=> did nothing, the only change was SCS = Disabled ( no charger )
so in my view , it must be something in the Assistant ESS
so i installed the Assistant ESS again, BUT nothing selected that was with the name Lithium or BMS ,so lead acid style .
i uploaded that to the MP2 ( restarted ) and rebooted the Cerbo gx the same time
for a split second i saw SCS - Active but that went away to SCS - Disabled ( external )
I know it can work, 11 months ago i had Lead acid batteries with ESS installed , 100% sure it worked than . ( on Quattro 8k = Changed it to MP2 5000 )
but for some reason i can not get it to work now.
the reason i want this to work =
I have to many PV for my battery ( 200A max. input ) and i have 200+ Amps from my PV, so i want to limit that to about 180A
i do not care about the BMS style - i only want the readout from BMS and Victron regulates everything, just like its no " NO BMS Controle " ( under the max. voltage and max. current of the specs of the BMS )
= like a Lead Acid style setup but with lifepo4 cells
