 === Introduction ===
-Hub-4 is a Grid-parallel Energy Storage system, using the Multi or Quattro bidirectional inverter/charger as its main component. It optimizes self-consumption: at times when there is excess PV power, the PV energy is stored in the battery. And that stored energy is then to power the loads at times when there is a shortage of PV power.

   - Advanced \\ Same as standard, but more flexibility is given to implement time shifting, load management or other energy management optimization algorithms. 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 4xx firmware. Contact your Victron representative for the firmware files. Update instructions are [[updating_firmware:updating_ve.bus_products|here]].
-  - The RS485 to USB interface cable from the CCGX to the AC sensor can be extended up to 100 meters max.

For example the EM24DINAV53DISX, which uses Current Transformers and can therefore work in systems > 63A per phase. Note that this model is not stocked by Victron Energy, we recommend to purchase it locally.

 In a multi-phase system, the charge current is configured per phase. There is not a total charge current which the system adheres too. This means that, for example when there is a relatively small battery bank, and a huge over production of PV on L1, and not on the other phases, only part of that over production on L1 will be used to charge the battery.

 ==== BatteryLife ====
-The battery life feature prevents low battery state of charge over a long period. This may happen when there is insufficient PV power available to recharge the battery every day, for example in winter.
-BatteryLife will make sure that, on average the battery will be recharged to 70 to 100% SOC, every day.
+=== What does it do? ===
+In case the expected Solar energy reduces, because of less sun shine, the system will automatically increase its low SOC limit. So that, with this reduced expected Solar Energy, the battery will still be fully charged at the end of the day to approx 100%.
+In case the expected Solar energy increased, because of more sun shine, the system will automatically decrease its low SOC limit. So that, with this increased expected Solar Energy, the battery will still be fully charged at the end of the day to approx 100%.
+Ask yourself, "Why should the battery be fully discharged, and stay that way? With as a result no reserve power in case of mains failure, and possible also a damaged battery".
+=== Details ===
+The BatteryLife feature prevents low battery state of charge over a long period. For example in winter, when there is insufficient PV power available to recharge the battery every day.
+BatteryLife ensures that, on average, the battery will be recharged to 100% SOC, every day.
+It has several advantages:
+  * Operating in a partial state of charge is bad for lead acid battery life
+  * Certain lithium batteries need to be fully charged regularly, in order to balance. This includes the [[https://www.victronenergy.com/batteries/lithium-battery-12-8v|Victron 12.8V lithium batteries]], and therefore it is also mandatory to enable BatteryLife for those batteries.
+  * In case of mains failure, it is best to have spare energy available to power the loads from the battery. Continuously operating in a low state of charge serves no purpose.
 To do this we introduce a dynamic lower limit on the state of charge. Discharging is allowed only if the state of charge exceeds the limit. The limit is adjusted every day. On days with little or no surplus PV power the limit will be raised. And on 'good' days the limit is lowered again.

-===== 9. Using the Wired HUB-4 AC Sensor to measure PV Inverter output =====
-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 to 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.
+===== 11. Troubleshooting =====
-There are 3 options to connect the extra AC sensor:
+=== The system is not discharging ===
-    - Wired connection with an extra RS485 to USB converter cable. Works just like the grid meter.
-    - Wired connection with modbus multidrop (both AC sensors connected to the same RS485 to USB converter cable). In this case you need to change the modbus address of one of the AC sensors (see below).
-    - Wireless connection: the AC sensor is connected to an additional Zigbee to RS485 converter just like the grid meter. Also requires change of the modbus address.
-Changing the modbus address:
+  - Is the battery already fully discharged?
-    - Press the joystick down until until the display shows 'Pass'. The joystick on the right side on the display, above the front selector).
+  - Is State of Charge at or below the [[#batterylife|BatteryLife]] level?
-    - Press the joystick down again and release immediately.
+  - Is the system in [[#sustain_mode|Sustain mode]]?
-    - Press the joystick right several times until 'Address' appears. Press the joystick down. Now you can adjust the address by pressing the joystick up and down. Set it to 2.
-    - Press down again. 'Baudrate' appears.
-    - Press down again twice. 'Address' appears again.
-    - Press right until 'End' appears.
-    - Press down. The display now shows measurements again.
-On a single phase setup, you can use a single AC sensor to measure both grid and PV inverter. For wiring see the diagram below.
+=== The system is not charging ===
-{{:system_integration:carlo-l1grid-l2pv.jpg|}}
+  - Is the battery already fully charged?
+  - Is there a high load?
-On the CCGX go to the grid meter in the Wired AC sensor settings. Make sure 'Phase type' is set to 'Single phase' and 'PV inverter on phase 2' is enabled.
+=== The system is in passthrough, not charging and not discharging ===
