 SOC stands for State of Charge. The BMV SOC is the state of charge measured by the BMV Battery Monitor. It calculates this value based on measurements taken by the shunt. And, assuming the shunt is installed in the correct place in the system, it takes into account all the loads and chargers.
-The SOC taken from VE.Bus is calculated by our Multis and Quattros. To calculate the SOC, they use only the internally measured charge and discharge currents. Because of this you can only use it in a system where you have only AC loads, and no other (solar) chargers. The battery capacity can be configured with VEConfigure.
+The SOC taken from VE.Bus is calculated by our Multis and Quattros. To calculate the SOC, they use only the internally measured charge and discharge currents. Because of this you can only use it for some system types, see [[https://www.victronenergy.com/live/ccgx:start#battery_state_of_charge_soc|here for which ones]]. The battery capacity can be configured with VEConfigure.
 **BMV SOC vs VE.Bus SOC algorithm**  The BMV has the advantage in its calculations that it sees all DC currents: so this includes MPPT solar charger currents, DC loads (typical in marine and automotive applications, for example alternators, lights and pumps), or other DC chargers. The Multi and Quattro have the advantage that it knows when the bulk state is finished, and can then sync the VE.Bus state of charge to 80%. Instead of (as the BMV does) having to wait until the battery is really full (sync parameters are met), and only then will it sync to 100%.

+These graphs work on information calculated by the GX device (Cerbo GX or Venus GX), based on energy counter values read from connected devices.
 General requirements:
-  * Color Control GX with latest version
+  * [[venus-os:start|GX device]] eg Cerbo GX with latest version
   * Multi or Quattro with a 26 or 27 hardware: the 7 digit firmware number needs to start with 26 or 27. If it starts with 19 or 20, the product has old hardware. To get the consumption and solar yield tabs working for these products, the product needs to be replaced or get an control board upgrade.
   * Multi or Quattro firmware needs to be recent as well:

-  * There's an issue with hub-4 systems where grid power and PV power are measured using a single AC sensor (grid on phase 1 and PV power on phase 2). In this case the solar to grid value is incorrect. We are working on a solution of this issue.
+  * There's an issue when a single EM24 three phase meter is used to measure both grid- and PV-power (grid on its phase 1 terminals and PV power on phase 2). In this case the solar to grid value is incorrect. The solution is to use an ET340 or ET112. See [[energy-meters:start|Energy Meters]] for details.

-Other notes:
+=== 'Has DC system' related limitations ===
+‘Has DC system’ is a feature on a GX device. When that config switch is enabled, a new box called 'DC Power' appears on the GX display. Its value is calculated from the differential between the power measured by the bms or battery monitor, and the power flow measured by the inverter/charger and other sources that are actively monitored by the GX. Its typical use is in Marine and Automotive applications, as they have alternators, and lights, fridges, and many more DC loads. For more details, see the GX device manual.
-  * DC consumption or charging, for example by an alternator or other charger that is not reporting to the CCGX, is not yet taken into account in the calculations.
+  * If this feature is enabled, and the used battery monitor is a BMV 700 or 712, then the minimum required BMV firmware version to make the VRM Energy dashboards operate correctly is v3.08.
-  * A system with multiple mppts, even a mix of VE.Can and VE.Direct, is supported: the algorithm will totalize all the counters
+  * The calculated value for 'DC Power' is not used in any way by the GX, beyond just being displayed 'on screen'. In particular it is not logged on the VRM portal and it is not included in system calculation and it does not appear as part of the recorded Solar Yield.
+=== Other limitations ===
+  * A system with multiple MPPTs, even a mix of VE.Can and VE.Direct, is supported: the algorithm will totalize all the counters - as long as they are all actively monitored.
   * Multiple AC current sensors measuring multiple PV inverters is supported as well.
-  * Other brands (not Victron) Solar Chargers will not work: the CCGX needs to read the kWh data from the solar charger.
+  * These overviews work correctly when Victron Solar Chargers are used. When one or more non-Victron solar chargers are used, the system cannot read their Energy yields, and because of that the resulting overviews are incorrect and unreliable.
-  * The VGR, VGR2 and VER do not work: only the CCGX provides the necessary kWh data for these graphs.
+  * The VGR, VGR2 and VER do not provide any energy data data.
-  * Combining MPPT Solar Chargers and PV Inverters in a system works.
+  * Combining MPPT Solar Chargers and PV Inverters in a system is supported.
-===== How does the system overview work? Old products are still showing =====
-This is the system overview on the VRM Portal:
-{{  :vrm_portal:faq-3.png?direct&  }}
-It shows all products, their firmware version and some other additional information. After disconnecting a product from the Color Control GX or the Victron Global Remote, it is necessary to power cycle it (the CCGX or VGR). This will make the VRM Portal to empty the list and re-populate it based on the new information.

@@ Line 69: / Line 67: @@
 The screensaver is disabled by default but can be configured in your profile settings to automatically show after a period of inactivity. You can also open the screensaver directly by pressing the "s" key twice.
-The screensaver displays which source of energy your site is currently running on. This is determined by looking at which source of energy (the sources being solar, generator, battery and grid) is delivering the largest amount of energy to consumers (locally connected devices using the energy). Then, if no consumers are using any power, it looks at which source provides the largest amount of energy to the battery. Then, if no battery is connected or it is not being charged, it looks at which source is delivering the most energy back to the grid. If at this point the source is still not determined, apparently no energy is being produced or used anywhere, and the state defaults to 'on grid'.

@@ Line 85: / Line 95: @@
 In case the data is too old, which means older than would have been expected from the configured logging interval, the value will be shown red. Use the System overview page to check if there are products that are not connected anymore. One typical example where this might happen is:

+If you are seeing that the GX device is connecting to VRM, then it can take up to a few hours or more for the data to sync to VRM and for the updates to show, depending on how much data there is to catch up.
