 +‘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 typicla use are Marine and Automotive applications,​ as they have alternators,​ and lights, fridges, and many more DC loads. For more details, see the ccgx manual.
  
-What is ‘Has DC system’? If 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. Typically used for Marine and Automotive applications. For more details, see the ccgx manual. +  ​* 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.

   * 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.   * The calculated value for 'DC Power' is not used in any way by the GX, beyond just being displayed 'on screen'​.

   * 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.   * 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.   * Multiple AC current sensors measuring multiple PV inverters is supported as well.
-  * These overviews work on energy data read from Victron Solar Chargers. ​They will not work correctly when non-Victron solar chargers are used. They PV yield (kWh) will not be accounted forand the rest of the calculations will become inaccurate.+  * These overviews work correctly when Victron Solar Chargers ​are usedWhen 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 provide any energy data data.   * The VGR, VGR2 and VER do not provide any energy data data.
