4.4.3 Shared Temperature Sense (STS)
Select the temperature sensor to use; and the GX device will send the measured battery temperature
to the Inverter/charger system as well as all connected Solar Chargers.
Selectable sources for the battery temperature are:
BMV-702 battery monitor
BMV-712 battery monitor
Lynx Shunt VE.Can battery monitors
Temperature inputs on a Venus GX (and same for other GX devices that have a temperature
input)
Multi/Quattro inverter/charger
Solar Chargers (if fitted with a temperature sensor)
4.4.4 Shared Current Sense (SCS)
This feature forwards the battery current, as measured by a battery monitor connected to the GX
device, to all connected solar chargers.
The solar chargers can be configured to use the battery current for its tail current mechanism that
ends absorption when the current is below the configured threshold. For more information about that,
refer to Solar charger documentation.
This feature only applies to systems that are not ESS, and/or don't have a managed battery, since in
both of those cases the MPPT is already externally controlled.
Requires MPPT solar charger firmware v1.47 or newer.
4.5 DVCC Features when using CAN-bus BMS Battery
This chapter applies to all systems where an intelligent battery BMS is installed, and connected via
CAN-bus. Note that this does not include the Victron VE.Bus BMS.
Such intelligent BMS sends four parameters to the GX device:
1. Charge voltage limit (CVL): the maximum charge voltage that the battery currently accepts.
2. Charge current limit (CCL): the maximum charge current requested by the battery.
3. Discharge current limit (DCL): the maximum discharge current as requested by the battery.
For all three parameters, some types of batteries transmit dynamic values. For example they
determine the maximum charge voltage based on cell voltages, state of charge, or for example
temperature. Other makes and brands use a fixed value.
Here is the page in the menus showing the parameters:
