2.4.1 Which device should I use for SOC calculation?
There are three products types that calculate State Of Charge (SOC). The CCGX itself does not
calculate SOC, it only retrieves it from the connected devices.
The three products that calculate SOC are:
Battery Monitors, such as the BMVs, the Lynx Shunt, or the Lynx Ion BMS1.
Multi and Quattro inverter/chargers2.
Batteries with built-in battery monitor and a (mostly CAN bus) connection to the CCGX.3.
When to use what?
If you have a battery with build-in battery monitor, such as a BYD or Freedomwon battery; its easy.
Use that.
If the MultiPlus or Quattro inverter/charger is the only source of charge to the batteries and the only
draw then it can function as a basic battery monitor because it counts what went in and counts what
comes out. No need for a dedicated battery such as the BMV.
If the systems consists of an inverter/charger, MPPTs and a GX device, then there is still no need to
add a dedicated battery monitor.
For any other system types, such as a boat or vehicle with DC lights and other loads, a dedicated
battery monitor will be required.
2.4.2 The different solutions explained in detail
(A) Battery and Multi or Quattro (a typical backup system)
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:
Enable and configure the Battery Monitor in VEConfigure.1.
In the CCGX, in Settings → System setup, verify the selected Battery Monitor. It should be set to2.
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.
