If I want to have precise control of the charge current going to the battery, will I need a Cerbo-GX with DVCC enabled or is a VE.Smart Network sufficient? If I have attached varying loads, the MPPT should adjust its current output to match the loads, and charge current. For example, during bulk charging, the MPPT max current output should rise and fall to meet both the max charge current and the load demands at any point in time:
In the MPPT manual, I read the following under the VE.Smart Networking heading:

A comment on the Victron community forums says that a GX device is required with DVCC.

Is a GX device with DVCC still required for precise charge current control or is VE.Smart network alone enough?
Thanks!
Charge Current | Load Current | Total MPPT Current |
---|---|---|
30A | 4A | 34A |
30A | 2A | 32A |
30A | 3A | 33A |
In the MPPT manual, I read the following under the VE.Smart Networking heading:
- Current sensing - The measured battery current is used by the charger so it knows the exact tail current at which the absorption stage should end and the float (or equalisation) stage should start. To measure the charge current all charge currents from all chargers are combined, or if a battery monitor is part of the network the actual battery current will be used.
