 === Operating modes ===
   - Standard \\ The system runs automatically, and uses excess energy harvested during the day to fill the gaps when there is not enough PV power available. Easy configuration in Assistants and on the Color Control GX.
-  - Advanced \\ same as standard, but more flexibility is given to implement time shifting, load management or other energy management optimization algorithsm. Either by ModbusTCP commands or by running additional self implemented code on the Color Control GX. Often the best of both worlds: complete flexibility and benefit from the VRM Portal and all other functionality already available on the CCGX, without having to add additional cost of extra PLCs or other control modules.

 Notes:
-  - The Multi or Quattro used needs to be a recent type with the new microprocessor (26xxxxx or 27xxxxx). All units currently shipping have this new microprocessor. Also, the Multi or Quattro needs to run the latest 3xx firmware. Contact your Victron representative for the firmware files. Update instructions are [[updating_firmware:updating_ve.bus_products|here]].

For example the EM24DINAV53DISX, which measures using Current Transformers. Note that this model is not stocked by Victron Energy, we recommend to purchase it locally.

-During Sustain Mode, the charger is enabled to keep the DC voltage at the sustain level. The maximum charge current during system is 5A. Sustain mode is left as soon as the battery voltages rises 0.1V above the sustain level.

 Note that the normal Hub-4 regulation is suspended during Sustain. And note that, for non-lithium systems, the sustain level is 12 V for the first 24 hours, and after that it is raised to 12.5 Volts DC.

 Instead of used for the Hub-4 regulation, the same three phase meter can be configured to measure output of a PV Inverter. Make sure the check Paragraph 1.3 in the [[ccgx:start|Color Control GX Manual]] for other options of measuring PV Inverter output.
-Installation is similar to the AC sensor on the grid. Terminals 1, 4 and 7 should face the PV inverter. On the CCGX change the //Role// of the meter to //PV inverter//. You can now also chose its //Position//. In the case of a Hub4 setup, this must be //Input 1//.

If you want to connect a single phase PV inverter to a 3-phase system connect all 3 phases to the grid phasing terminals (3, 6 and 9). Now you can chose on which phase you want the PV inverter by connecting the L1 line of the PV inverter to terminal 1, 4 or 7.
 There are 3 options to connect the extra AC sensor:

+This message is a bug. There is no need to reset the device. The mechanism that erroneously triggers that message will be removed in a future VE.Bus firmware version.
