-These tabs work on information sent by the Color Control GX.
+{{  :vrm_portal:faq-1.png?direct&  }}
-General requirements:
+Consumption:
-  * Color Control GX with latest version (v1.20 or newer)
+{{  :vrm_portal:faq-2.png?direct&  }}
-  * 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 products 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:
-      * 1xx firmware (virtual switch), needs to be xxxx154 or newer
-      * 2xx firmware (assistants gen1), needs to be xxxx205 or newer
-      * 3xx firmware (assistants gen2), needs to be xxxx300 or newer
-      * More information: [[http://www.victronenergy.com/upload/documents/manual-VE.Bus-firmware-versions-explained-EN.pdf|VE.Bus firmware versions explained]]
-Extra requirement for systems with AC Coupled PV, for example hub-2:
+These graphs work on information calculated by the Color Control GX, based on energy counter values read from connected devices.
-  * PV Inverter power measured with our AC Current Sensor or our Wireless AC Sensors
+General requirements:

-Extra requirement for systems with DC Coupled PV, for example hub-1:
+Extra requirements for systems with AC Coupled PV (ie a grid-tie inverter on the output), for example ESS:
-  * BMV-700 or BMV-702. The BMV-600 series do not work because they do not calculate discharged and charged energy (kWh)
+  * PV Inverter power and energy needs to be measured. For example a [[ccgx:ccgx_fronius|direct Fronius connection]], or with our [[https://www.victronenergy.com/accessories/AC-Current-sensor|AC Current Sensor]] or [[https://www.victronenergy.com/accessories/wireless-AC-sensor|wireless AC Sensors]]
-  * For Multis or Quattros connected via our VE.Bus to VE.Can interface: this interface does not yet support the kWh data needed for these graphs.
+  * 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.
+  * When using the AC Current Sensor, make sure to use the latest version of the Assistant, as released in October 2014. [[https://www.victronenergy.com/blog/2014/10/13/ac-current-sensor-assistant-no-more-pv-power-at-night/|more info]]

   * A system with multiple mppts, even a mix of VE.Can and VE.Direct, is supported: the algorithm will totalize all the counters
   * Multiple AC current sensors measuring multiple PV inverters is supported as well.
-  * Three phase and/or parallel Vebus systems works ok.
   * Other brands (not Victron) Solar Chargers will not work: the CCGX needs to read the kWh data from the solar charger.
   * The VGR, VGR2 and VER do not work: only the CCGX provides the necessary kWh data for these graphs.
   * Combining MPPT Solar Chargers and PV Inverters in a system works.
-  * Systems with multiple Multis or Quattros per phase (parallel systems) need to run firmware version xxxx159, xxxx209, xxxx306 or higher, to support parallel kWh counting. Otherwise there are two options:
-    - Use an earlier VE.Bus firmware in combination with CCGX version v1.20 and lower: incorrect values will be reported.
-    - Use an earlier VE.Bus firmware in combination with CCGX version v1.21 or newer: kWh measurements (for the solar yield and consumption tab) will not be reported.

This will make the VRM Portal to empty the list and re-populate it based on the new information.

 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'.

+===== What is the column logtime Offset in the XLS/CSV download for? =====
+Use it to see the quality of the Internet connection.
+The values relate to the backlog feature. Usually the column is either empty, or you see series of rows with a decreasing logtime offset. Once zero, the columns are empty again. These series mean that there was a problem with the Internet connection. And the value shown is the number of seconds for which that particular row of data had been backlogged.
