Victron energy Venus GX Manual page 42

No battery monitor is required: the Multi or Quattro is the only product connected to the battery and
has full control over all charge and discharge currents. Therefore it can calculate the correct SOC
itself.
Configuration:
1. Enable and configure the Battery Monitor in VEConfigure.
2. In the CCGX, in Settings → System setup, verify the selected Battery Monitor. It should be set to
the Multi or Quattro.
(B) Battery with Multi or Quattro and MPPT Solar Chargers -ALSO- An EasySolar with CCGX built-in
No battery monitor is required, as long as all MPPT Solar Chargers are Victron products and are
connected to the CCGX. The CCGX will continuously read the actual charge current from all solar
chargers, and send the total to the Multi (or Quattro) which then uses that information in its SOC
calculations.
Configuration:
1. Enable and configure the Battery Monitor in VEConfigure.
2. On the CCGX, in Settings → System setup, verify the selected Battery Monitor. It should be the
Multi or Quattro.
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 here - 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
