Introduction And Features - Victron energy Venus GX Manual

4.1 Introduction and features

Enabling DVCC changes a GX device from a passive monitor into an active controller. The available
features and effects of enabling DVCC depend on the type of battery used. The effect also depends on
the installed Victron components and their configuration.
Example 1 - Managed CAN-bus batteries For example, in systems with an Managed CAN-bus BMS
battery connected, the GX receives a Charge Voltage Limit (CVL), Charge Current Limit (CCL),
Discharge Current Limit (DCL) from that battery and relays that to the connected inverter/chargers
and solar chargers. These then disable their internal charge algorithms and simply do what they're
told by the battery. There is no need to set-up charge voltages or choose the charge algorithm type.
Example 2 - Lead batteries For systems with lead batteries, DVCC offers features such as a
configurable system wide charge current limit, where the GX device actively limits the
inverter/charger in case the solar chargers are already charging at full power. As well as shared
temperature sense (STS) and shared current sense (SCS).
