3. In the same menu, verify that the option 'Use solar charger current to improve VE.Bus SOC' is enabled. Note that this is not a
setting - it just an indicator of an automatic process.
Note that this feature requires recent firmware versions in both the Multis or Quattros (402 minimum), and the CCGX (v2.06
minimum).
(C) Batteries with a built-in battery monitor
In cases where the system includes a battery which has a built-in battery monitor and SOC calculation - such as many of the
batteries listed
- a dedicated battery monitor is not required.
Configuration:
1. Connect the battery communications cable to the CCGX according to the instructions.
2. In the CCGX , in Settings → System setup, verify that the selected Battery Monitor is the battery.
Note that the Battery Monitor setting in VEConfigure3 is irrelevant. For systems like this, changing this setting will have no effect
on the charge or any other parameters in this type of system.
(D) Other system types
When there are more chargers, or loads, connected to the battery than just the Multi or MPPT Solar Chargers, a dedicated
Battery Monitor will be required. Examples are:
• House loads in Marine or Vehicle system.
• PWM Solar Chargers
• AC chargers, such as Skylla-is, Phoenix chargers, non Victron chargers, etc.
• Alternators
• DC-DC chargers
• Wind turbines
• Hydro turbines
In case a battery with built-in monitor is used, such as explained in (C), then that is the dedicated battery Monitor. Refer to section
(C).
Otherwise, install a BMV or Lynx Shunt VE.Can.
Configuration:
1. Configure the battery monitor as per its documentation.
2. In the CCGX , in Settings → System setup, verify the selected Battery Monitor.
3. It should be the BMV or Lynx Shunt Battery Monitor.
4. Finished.
Note that the Battery Monitor setting in VEConfigure3 is irrelevant. For systems like this, changing this setting will have no effect
on the charge - or any other parameters - in this type of system.
5.2.3. Notes on SOC
• Note that this is all about showing an accurate state of charge to the user, rather than being required for an efficient system.
The SOC percentage is not used for battery charging. It is, however, required when a generator needs to be started and
stopped automatically based on battery SOC.

5.2.4. Selecting SOC source
(Settings → System Setup → Battery monitor)
In the image below you can see a range of selectable choices for the SOC values which are shown in the main Overview screen.
Choose the source you want to see on the main Overview screen of your CCGX.
