8.2. Battery state of charge (SoC)
8.2.1. Which device should I use for SoC calculation?
There are three products types that calculate state of charge (SoC). The VGX 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, SmartShunt, Lynx Shunt VE.Can, Lynx Smart BMS or the Lynx Ion BMS
Multi and Quattro inverter/chargers
Batteries with built-in battery monitor and a (mostly BMS-Can) connection to the VGX.
When to use what?
If you have a battery with built-in battery monitor, such as a BYD or Freedomwon battery; its easy, use that. If not, then the options depend on the type of system:
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 monitor 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 RV with DC lights and other DC loads, a dedicated battery monitor will be required.
8.2.2. The different solutions explained in detail
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.
In the VGX, in Settings → System setup, verify the selected battery monitor. It should be set to the Multi or Quattro.
Battery with Multi or Quattro and MPPT Solar Chargers or a EasySolar with GX device built-in
No battery monitor is required as long as all MPPT solar chargers are Victron products and are connected to the VGX. The VGX 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:
Enable and configure the battery monitor in VEConfigure.
On the VGX, in Settings → System setup, verify the selected battery monitor. It should be the Multi or Quattro.
In the System status menu, verify that the option 'Use solar charger current to improve VE.Bus SOC' is set to On. 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 VGX (v2.06 minimum).
Battery 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:
Connect the battery communications cable to the VGX according to the instructions.
In the VGX, in Settings → System setup, verify that the selected battery monitor is the battery.
Note
Note that the battery monitor setting in VEConfigure 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.
Other system types
When there are more chargers or loads than just the Multi or MPPT solar chargers connected to the battery, a dedicated battery monitor is required. Examples are:
House loads in Marine or Vehicle system.
PWM solar chargers
AC chargers, such as Skylla-is, Phoenix Smart IP43 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 (3), then that is the dedicated battery monitor. Refer to section (3). Otherwise install a BMV, SmartShunt or Lynx Shunt VE.Can.
Configuration:
Configure the battery monitor as per its documentation.
In the VGX, in Settings → System setup, verify the selected battery monitor.
It should be the BMV, SmartShunt, Lynx Smart BMS or Lynx Shunt battery monitor.
Finished.
Note
Note that the battery monitor setting in VEConfigure 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.
8.2.3. 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.
More information:
VRM Portal FAQ - difference between BMV SOC and VE.Bus SOC
See Configurable Parameters Section on Battery monitor selection and Has DC system.
8.2.4. Selecting SoC source
(Settings → System Setup → Battery monitor)
In the image above 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 VGX.
In the same image we have chosen the Automatic setting. When automatic is selected, the System setup screen will be as shown in the image below.
The 'Automatic' function uses the following logic:
When available, it will use a dedicated battery monitor, such as the BMV, SmartShunt, Lynx Smart BMS or a Lynx Shunt VE.Can, or a battery with built-in battery monitor.
When there is more than one of those connected, it will use a random one - although you can select one manually.
When there is no dedicated battery monitor, it will use the VE.Bus SoC.
When should I use the 'No battery monitor' option?:
Use that in systems where:
there is a Multi or Quattro installed
no BMV or other battery monitor is installed
the system has other DC loads or other chargers connected to the same battery, which are not connected to the VGX.
A short explanation: The VE.Bus SoC determined by the Multi or Quattro is incorrect in the above situation as it does not take into account the discharge and charge currents by those other DC loads and also unmonitored chargers.
8.2.5. Details on VE.Bus SOC
While the Inverter/Charger is in bulk, the SoC will not rise above the value as set in VEConfigure for the 'State of charge when Bulk finished' parameter on the General tab; default 85%. In a system with solar chargers, make sure that the absorption voltage as configured in the MPPT is slightly above the same setting in the inverter/charger. The latter needs to recognise that the battery voltage has reached the absorption level. If it doesn’t, the SoC will be stuck at the earlier mentioned End-of-bulk percentage, default 85%.
8.2.6. The System Status menu
The System Status menu (Settings → System setup → System Status) contains diagnostic flags that can be useful in diagnosing problems with the system. Note that nothing can be configured here. The on/off flag depends on how a system is set up and what devices it contains.
Their meaning in detail are:
Synchronise VE.Bus SoC with battery:
If On, it indicates that the activated battery monitor in the Multi/Quattro is synchronising its SoC with that of a better source (a BMV or BMS in the system). The system does that automatically.
Use solar charger current to improve VE.Bus SoC:
In a VE.Bus system with no other battery monitor (no BMS, no SmartShunt, no managed battery) but with solar chargers, the solar charge current is taken into account and helps improve the SoC calculation of the internal Multi/Quattro battery monitor. The system does this automatically and indicates that it is active by displaying On.
Solar charger voltage control:
If on, this indicates that the solar chargers are not following their own internal charge algorithm. They're getting a voltage setpoint from somewhere else. Either
a managed battery or
in an ESS system, they get it from the Multi/Quattro.
Solar charger current control:
This indicates that the solar chargers are current limited by the system. In most cases the limiting device is a managed battery or a user-defined Maximum charge current in the DVCC menu.
BMS control:
It indicates that the BMS is controlling the charge voltage setpoint (and not using the value set for absorption and float in the Multi/Quattro or solar charger).
8.3. Customise the logo on the Boat & Motorhome page
It is possible to use a custom logo on the Boat & Motorhome page.
Type the following address into the web browser of a device connected to the same network, using this address as a template: http://venus.local/logo.php or http://[ip-here]/logo.php (inserting your device’s IP address between the square brackets).
The IP address can be found by going to Settings → Ethernet or WiFi. Once the page is loaded, choose an image file from your device. Reboot the GX device.
8.4. LEDs and Push-button
8.4.1. LEDs
On the side of the Venus GX there is a LED. During power-up it goes through these states:
Boot-up
Stage 1: Both green and red illuminate briefly and faintly (it's hard to see the green) for approximately 1 second.
Stage 2: Red illuminates for approximately 1 second.
Stage 3: Green illuminates for approximately 0.5 seconds.
Stage 4: Both green and red illuminate briefly and faintly (it's hard to see the green) for approximately 1 second.
During operation
Slow blinking: built-in WiFi access point disabled
Fast blinking: built-in WiFi access point enabled (default)
Slow blinking is once per second. Fast blinking is twice per second.
8.4.2. Small button located to the right of the green 14-Terminal Connector Block
Short press: WiFi Access point on/off
A single short press toggles the internal WiFi access point on and off. The LED indicates its state: when the LED blinks green slow, then the built-in Access Point is disabled. when the LED is green and blinking fast, then the built-in Access Point is enabled.
Long press: reset all network settings to factory defaults
Press and hold the small button for a minimum of four seconds. The LED will stay on for 2 seconds to indicate that the log press has been recognised; then release the button again.
Ethernet is set back to DHCP
WiFi Access Point is enabled
Remote Console password is disabled
Remote Console on LAN and on VRM is enabled
The same button is available on the Octo GX, button is marked SD_BOOT and available under the lid at the top.
8.5. Temperature relay configuration
It is possible to configure the built in Relay 1, and Relay 2 (if applicable), to activate and deactivate based on temperature.
See Connecting Temperature Sensors section for compatibility and connection instructions. Confirm the temperature sensors are correctly connected and reporting temperature in the Device List.
The temperature relay is controlled from Settings Menu → Relay → Function (Relay 1/2) → Temperature. Once enabled, the Temperature control rules menu will appear in the Relay menu, and inside the temperature sensors that have been detected.
Each temperature sensor can be used to control the relay. Select the temperature sensor you wish to use to control the relay. The temperature sensors that aren't used will display "No actions". It is possible to enable or disable the temperature relay control for each temperature sensor within this menu.
In GX products where two relays are available (Cerbo GX & Cerbo-S GX, Ekrano GX), it is possible to have a single temperature sensor control both relays. It is also possible to have a single relay controlled by multiple different temperature sensors. For example, a Cerbo GX with 2 lithium battery heat pads, and only using both simultaneously when necessary.
In the Relay → Temperature control rules → Temperature sensor menu
Enable Relay activation on temperature
Assign the relay control to Relay 1
Set the Activation value to 5 degrees
Set the Deactivation value to 10 degrees
If that is insufficient to maintain the battery temperature above 5 degrees, you may wish to connect a second heat pad contactor to Relay 2 as well.
Move down menu to Condition 2
Assign the relay control to Relay 2
Set the Activation value to 4 degrees
Set the Deactivation value to 6 degrees
This will mean that Relay 1 will be active if the battery temperature falls to 5 degrees. If the temperature continues to fall below 5 degrees to 4 degrees, then the second heat pad will be engaged via Relay 2. If that is sufficient to raise the temperature back to 6 degrees, Relay 2 will deactivate, and then Relay 1 will remain active until battery temperature returns to 10 degrees.
Note that the physical wiring contacts are available for Relay 1 in Normally Open and Normally Closed configurations.
Caution
Note the specifications for the power limits of the relays. It may be necessary to connect appliances via an additional contactor if power requirements exceed the relay power limit specification.
