TCP Modbus - registers for values from MPPT regulators

I’m trying to get some information about the daily production of controllers, but unfortunately I’m only able to do it for the first MPPT controller.

If i read registers 784,785,786,787 there are values, but only from first regulator.

I need to read the same informations from other regulators.

There are avialble registers 3708…3727 but i can read only zero, no correct values.
Next possibility are registers 3148…3167 but there i don’t have any answer.

Please, if exists any possibly how to read these informations via TCP Modbus, give me feedback. Thanks.

If you go to Settings → Services → Modbus TCP → Available services, what do you see there?
Do you see all controllers?
If yes, you may need to change the device ID with the ones there for reading individually.


I can see ID Units:
com.victronenergy.battery - ID225
com.victronenergy.solarcharger - ID1
com.victronenergy.temperature - ID26
com.victronenergy.temperature - ID25
com.victronenergy.temperature - ID24
com.victronenergy.solarcharger - ID100
com.victronenergy.vebus - ID227
com.victronenergy.hub4 - ID100
com.victronenergy.system - ID100

registers 3708…3727 are in com.victronenergy.solarcharger ID1 or ID100.
I tried all of IDs from CERBO ID list (1,100,225,227…)
I can read this registers via TCP Modbus (ID=1 or 100), but values in these registers are zero.

These registers are working (but that are values from MPPT 1)

These registers are not working (i expect values from MPPT 2 …)
