+Read Victron manuals for guidance on product features, functions, and parameters and for using the product safely.//**
-AES LiFePO4 batteries must be set up to work with Power Conversion and Monitoring devices in either an Open Loop or Closed Loop configuration.
+**WARNING: ELECTRIC SHOCK AND FIRE HAZARD**
-AES LiFePO4 battery charge and discharge settings in a Open Loop configuration are set up manually through the controller for the Power Conversion device at the time of installation. This is commonly referred to as a ‘lead acid drop-in replacement’ configuration. For information on Open Loop set up with Victron devices please visit the Discover Battery web site [[www.discoverbattery.com]] >> Solutions >> Solar >> Resources >> Application Note >>> Discover-AES-Lithium-Open-Loop-Integration-Victron-Energy.
+  * This equipment must only be installed as specified.
+  * Do not disassemble or modify the battery.
+  * If the battery case has been damaged, do not touch exposed contents.
+  * There are no user-serviceable parts inside.
-In a Closed Loop configuration the battery charge and discharge rates and settings are dynamically controlled by the BMS of the AES LiFePO4 Battery over a connection with the power conversion devices in the network. These instructions are for a Closed Loop configuration.
+**Failure to follow these instructions can result in death or serious injury.**
-To connect with the communication network of a specific brand of inverter charger or solar charge controller, the LYNK Communication Gateway requires an AES LYNK Edge Card with the appropriate communication port.
-.2 Minimum Battery Capacity
+**CAUTION: ELECTRIC SHOCK HAZARD**
-Battery charge and discharge rates are managed automatically by the AES LiFePO4 Battery and Victron CCGX device. Using very large solar arrays with battery banks that are too small can exceed the operating limits of the battery to charge and possibly lead to the BMS triggering over-current protection. Battery capacity must be sized to accept the maximum charge
-current of the system, or the the charging devices must be curtailed to charge below the operating limit of the installed batteries. This value is derived by adding together the charge capacities of all inverter/chargers and solar charge controllers in the system. Additionally, battery peak capacity must be sized to support the surge requirements demanded by the load attached to the inverter. Match the sum of all inverter peak power values with the sum of all battery peak battery current values.

+===== 3. Overview =====
+==== 3.1 System Overview ====
+{{:battery_compatibility:aes-systemoverview.png?direct&600|}}
+The LYNK II Communication Gateway unlocks the full potential of a Discover Lithium battery by enabling the internal Battery Management System (BMS) to provide real-time data in a closed-loop configuration to other devices. This configuration allows hybrid inverter-chargers and solar charge controller systems to optimize control over the charging process in solar applications. LYNK II also enables the remote monitoring of Discover Lithium battery SOC and data logging of multiple sites using the data monitoring services offered by off-grid inverter systems.
+Discover Lithium batteries must be set up to work with power conversion and monitoring devices in either an open-loop or closed-loop configuration.
+In an open-loop configuration, charge and discharge settings are set up manually through the controller for the power conversion device at the time of installation.
+In a closed-loop configuration, the Discover Lithium battery's BMS sends the battery status over a network data connection with the power conversion device. Power conversion devices use the Discover Lithium battery BMS data to fine-tune the output of their charger and deliver other functional controls based on battery voltage, temperature, and percent State-of-Charge.
+If communication between the BMS and Victron inverter-charger is interrupted, the Victron inverter-charger stops charging until communication is re-established.
+==== 3.2 Minimum Battery Capacity ====
+Battery charge and discharge rates are managed automatically by the Discover Lithium battery and Victron Energy device. Using large solar arrays with battery banks that are too small can exceed the operating limits of the battery to charge and possibly lead to the BMS triggering over-current protection. Either curtail the charging below the operational limit of installed batteries, or the battery capacity must accept the maximum charge current of the system. This value is derived by adding the charge capacities of all inverter-chargers and solar charge controllers in the system. Additionally, battery peak capacity must support the surge requirements of the load attached to the inverter. Match all inverter peak power values with the sum of all battery peak battery current values.

+  * Connect at least one battery to the LYNK Port on the LYNK II.
+  * A network of batteries will communicate as one battery.
+  * No more than one network of batteries may be connected to the LYNK II.
+  * Proper system function requires network termination – some batteries and devices may auto-terminate.
+  * LYNK II requires power from one of three possible sources (13-90 VDC power supply, a USB device, or AEbus Port or LYNK Port enabled Discover Lithium battery).
+  * Discover Lithium batteries must be set to ON to supply power and communicate with LYNK II.

+LYNK II and AES RACKMOUNT battery modules are both internally terminated. No external termination is required when installing LYNK II with AES RACKMOUNT battery modules.
+Before connecting LYNK II to the VE.Can network, ensure that the Victron GX device uses firmware version 2.89 or later. Also, ensure the CAN out pins on the LYNK II are configured correctly.
+Insert one end of a CAT5e or higher communication cable into the LYNK II CAN out port and the other end into one of the two VE.Can ports (A-B) on the back of the Victron device. As the LYNK II is internally terminated, the external terminator provided with the GX is not required.
+{{:battery_compatibility:victron-gx-device-004.png?direct&600|}}
+  - VE.Bus: RJ45 socket for connecting to the Victron inverter.
+  - VE.Can: RJ45 socket for connection to LYNK II CAN Out.
+    * Insert a terminator in the other VE.Can port to terminate the CAN network.
+===== 5 Configuring Victron Products =====
+When the LYNK II is in a closed-loop network using the CANopen protocol, LYNK II will transmit real-time parameters from the Discover Lithium battery, including voltage, current, temperature, state of charge, and fault conditions, to a Victron Energy device. LYNK II also transmits charge voltage and current requests from the Discover Lithium battery to the Victron device.
+If there is a break in communication between the Victron Energy device and the LYNK II, the Victron device stops charging. Charging only resumes after communication between the Victron device and the LYNK II communication gateway is restored. If communication cannot be restored, you may have to set the system to open loop until an installation professional is available.
+As a precautionary measure, it is recommended that the inverter-charger be programmed with the correct voltage-based parameters before setting up the system to operate in a closed-loop configuration. If closed-loop communication fails, after the open loop parameters have been configured, turn the Victron device OFF and ON with the On/Off/Charger Only switch to enable the open-loop settings.
+==== 5.1 Setting Up Open-Loop Configuration ====
+Whenever possible, using a closed-loop configuration with Discover batteries and Victron devices is recommended. However, an open-loop configuration may be required if the closed-loop communication system encounters an issue, such as a failure of the LYNK II gateway, cables or connections, or the Victron device.
+In such cases, you may have to set the system to open loop until the issue is resolved. The following describes how to set up open-loop on Victron devices.
+{{:battery_compatibility:victron-configure3-005.png?direct&600|}}
+You will need the latest firmware on all connected devices. The following presumes familiarity with VE Configure software. After setting the voltage-based open-loop parameters using the VE Configure 3 software, ‘send’ all parameters to the inverter-charger and GX device and then restart the GX device.
+**Procedure**
+  - Set the Discover Lithium batteries to ON and the inverter to ON.
+  - Connect your computer to the Victron GX device or inverter.
+  - On the computer, start the VE Configure 3 software configuration tool.
+  - Enable and disable parameter values according to the tables below.
+  - Send the parameters in the following tables to the Victron inverter-charger and GX device.
+  - Toggle the On/Off/Charger Only switch to turn the inverter OFF and ON.

+==== 5.1 Setting Up Closed-Loop Configuration ====
+Refer to the latest Discover Energy Systems documentation for battery values and the latest Victron documentation for menu navigation and details on the setup procedure.
+  - Set the Discover Lithium batteries to ON and the Victron GX device to ON.
+  - Using a touch screen or other user interface of the GX device, set the VE.Can port and CAN-Bus BMS communication rate to 250 kbit/s to match the communication speed set up on the LYNK II communication gateway.
+**Device List > Settings > Services > VE.Can port > CAN-bus profile**
+  * Select **VE.Can & CAN-bus BMS (250 kbit/s)**
+ (Select Victron solar inverters may operate with CAN-bus BMS 500 kbit/s)
+{{:battery_compatibility:victron-closed-loop001.png?direct&400|}}
+  * Return to the Device List, and the Discover Lithium Battery should now appear as one of the devices.
+**Device List**
+{{:battery_compatibility:victron-closed-loop002.png?direct&400|}}
+**NOTE:** If **Discover AES** does not appear on the Device List, confirm that the CAT5e or higher communication cable is a normal patch type, not a cross-over type. Use manufactured cables to avoid bad crimps and reduce the risk of a poor connection.
+=== 5.1.1 Configurable Closed-Loop Settings ===
+During regular operation, the BMS sets the battery’s charge parameter limits, which the Victron GX device communicates to the inverter-charger and MPPT.
+To optimize the performance of a Victron system, manually set the following DVCC menu items using the Victron GX device and reboot the system.
+**Device List > Settings > DVCC**
+{{:battery_compatibility:victron-closed-loop004.png?direct&400|}}
+{{:battery_compatibility:victron-closed-loop005.png?direct&400|}}
+^ DVCC Menu ^ Setting ^
+^ DVCC (Distributed Voltage and Current Control | Forced on |
+^ Limit charge current | ON <sup>1</sup> |
+^ Maximum charge current <sup>1</sup> | Installed number of Discover batteries x rated Max Charge current|
+^ Limit managed battery charge voltage | Disabled |
+^ SVS - Shared voltage sense | Forced off <sup>2</sup> |
+^ STS - Shared temperature sense | Forced off |
+^ SCS - Shared current sense | ON |
+^ SCS status | (Displays the current status) |
+^ Controlling BMS | Automatic Selection |
+<sup>1</sup> Limit charge current works across the system. MPPTs are automatically prioritized over the mains. In cases where the BMS requests a maximum charge current different from the user-configurable setting, it uses the lesser of the two.
+<sup>2</sup> SVS should be set to OFF (Victron support has reported instances of conflicts when SVS is set to ON with a Lithium BMS).
+=== 5.1.2 Saving the Configurable Closed-Loop Settings ===
+**Device List > Settings > General > Reboot?**
+After the DVCC menu items have been set, reboot the system to complete the closed-loop configuration.
+{{:battery_compatibility:victron-closed-loop006.png?direct&400|}}
+**NOTE:** To avoid conflicting network information and data, do not use a Victron BMV battery monitor when using the LYNK II Communication Gateway.
