Color Control GX Manual

8.4.3. 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 Color Control GX (and same for other GX devices that have a temperature input)
• Multi/Quattro inverter/charger
• Solar Chargers (if fitted with a temperature sensor)

8.4.4. 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.

8.5. 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 the following 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:
For such batteries, there is no need to wire allow-to-charge and allow-to-discharge connections to the AUX inputs on a Multi or a
Quattro.
When inverting, ie in Island mode, Multis and Quattros will shut down when the max discharge current is zero. They will
automatically start again as soon as either AC mains returns, or when the BMS increases the max discharge current again.
See previous chapter, "Limit charge current", the user setting, for details about how the Maximum charge current is used, how it
prioritises solar and more.
All above means that setting up charge voltages or charge profiles in VEConfigure or VictronConnect is not necessary, and will
also have no effect. The Multis, Quattros and MPPT Solar Chargers will charge with the voltage as received via CAN-bus from the
battery.
