8.4. DVCC features for all systems

These features apply to all types of systems when DVCC is enabled: with or without ESS Assistant, and with lead or other normal
batteries as well as when an intelligent CAN-bus BMS connected battery is installed:

8.4.1. Limit charge current

This is a user-configurable maximum charge current setting. It works across the whole system. MPPT Solar Chargers are
automatically prioritized over the mains/generator.
This setting is available in the "Settings → "System Setup" menu on the GX device.
Particulars:
1) If a CANBUS-BMS is connected and the BMS requests a maximum charge current that is different from the user-configurable
setting, the lower of the two will be used.
2) This mechanism only works for Victron inverter/chargers and Solar chargers. Other chargers, such as Skylla-i's are not
controlled and also their charge current is not taken into account. The same applies for devices that are not connected to the GX
device, such as an alternator. Worded differently: the total charge current of the inverter/chargers and all MPPTs will be controlled,
nothing else. Any other sources will be extra charge current, unaccounted for. Even when installing a BMV or other battery
monitor.
3) DC Loads are not accounted for. Even when a BMV or other battery monitor is installed. For example, with a configured
maximum charge current of 50 Amps, and DC Loads drawing 20 Amps, the battery will be charged with 30 Amps. Not with the full
allowed 50 Amps.
4) Current drawn from the system by the inverter/charger is compensated for. For example, if 10A is drawn to power AC loads,
and the limit is 50A, the system will allow the solar chargers to charge with a maximum of 60 Amps.
5) In all situations, the maximum charge limit configured in a device itself, ie. the Charge current limit set with VictronConnect or
VEConfigure for the Solar chargers or Inverter/chargers will still be in effect. An example to illustrate this: in case there is only an
Inverter/charger in the system, and in VEConfigure or VictronConnect the charge current is configured to 50 Amps. And on the
GX Device, a limit of 100A is configured, then the working limit will be 50 Amps.

8.4.2. Shared Voltage Sense (SVS)

Works with VE.Bus devices and VE.Direct Solar Chargers.
The system automatically selects the best available voltage measurement. It will use the voltage from the BMS or a BMV battery
monitor, if possible, otherwise it will use the battery voltage reported by the VE.Bus system.
The voltage displayed on the GUI reflects the same voltage measurement.
Shared Voltage Sense (SVS) is by default enabled when DVCC is enabled. It can be disabled with a switch in the Settings →
System Setup menu.
