Limit MPPT Current in ESS Mode 3 via ModBusTCP

Hi,

I have a CerboGX with a MPPT 250/100 connected via Ve.CAN.

I looked at the ModbusTCP excel spreadsheet (CCGX Modbus Register List 2.80) and found no possibility to limit the output current of the MPPT on the DC Bus.

My question is: can the output current of the MPPT on the DC bus be limited (by a ModbusTCP accessable parameter)?

I am specifically not talking about a overvoltage feedin option that a Multiplus might provide.

Hi,

Register 2705 if you have dvcc and I understand you correct :)

Thanks for your answer. I am sorry that I reply so very late.

Reg 2705 says that it only applies to ess mode 2 and I run my system with ess mode 3 (external control), sorry that I did not specify that in the original question.
