Has the system been set up according to this page https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom#gx_device_settings


On the cerbo under battery and parameters what does it say there?With 2 you should have at least 50A

If weak ac is checked on the inverter programming, this can also happen since you havent mentioned solar i assume you are grid charging.

Hi,

thank you for answering.

In the meantime I've installed a third Pylontech US2000C.

But I see under Parameter only 25A, for my understanding this should be now 75 A.


Now to you questions:

Yes, the system is configured exactly to your offered page.

The weak AC is not checked.


Any ideas ?

Hello Mac, Maybe you can try to change other battery as the master.. See what happens then.
