Pylontech UP3000 DVCC not activated automatically

Hi i just installed 7 US3000 and followed this

https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom

for install


SYSTEM:

CCGX

BMV702

MPPT250|100

MPII 48/5000

all running latest alpha Firmware


According to the above install manual:

When the battery is correctly connected this will also set the following values automatically:

Venus Settings → System Setup Parameter Value

DVCC ON

Shared Voltage Sense OFF

Shared Temperature Sense OFF


I did not get DVCC set to ON in the CCGX and no auto config took place on any devices... any ideas why?

the batteries are visible in the CCGX devices tab and no apparent errors.


I ended up configuring everything manually but curious why DVCC did not work and potentially if there is an issue i need to address.

Hi Jim, no issue on your side. One on ours.

I’ll update the documentation.


thanks for pointing it out!

the issue is that DVCC does not auto config? or does not auto ON?

Yes, the issue is that the dvcc feature doesnt automatically switch on; you have to do it manually

When I turned on DVCC no settings were sent to the rest of my gear! i had to set everything manually... why?

So, in VEConfigure, there should be the limits recommended by Pylontech? The Victron settings are more conservative and protecting more the batteries.

Also in the above install documentation it states that:


5.3 Inverter Settings

In the Inverter tab of VEConfigure

VEConfigure Inverter Parameter Setting

DC input low shut-down 44V

DC input low restart 48V

DC input low pre-alarm* 48V


PylonTech recommended

DC input low shut-down 42V

DC input low restart 45V

DC input low pre-alarm* 45V
