Overview

This manual provides general settings and is not a comprehensive guide to the programming and configuration of a specific installation. An installation may have unique conditions or use cases that require modification or adaptations of values.
Installers must be capable of reviewing and adapting to the specifics of an installation and its specific use case and optimizing settings where needed.
The key steps required to install and configure the LYNK II Communication Gateway with compatible Discover Lithium batteries and power conversion equipment are as follows:

• Review and confirm equipment compatibility and correct sizing.
• Configure the LYNK II CAN out pins to match the CAN in pins of the power conversion equipment.
• Mount the LYNK II, connect the Discover battery communication network to either the LYNK Port or AEbus Port and then connect the CAN Out Port to the power conversion equipment’s communication network.
• Terminate all networks correctly.
• Set the LYNK II using LYNK ACCESS software to the correct protocol to enable closed-loop communication between the Discover batteries and the power conversion equipment.
• Set up the closed-loop configuration parameters on the power conversion equipment.

3.1 System Overview
The LYNK II Communication Gateway unlocks the full potential of a Discover Lithium battery by enabling the internal Battery Management System (BMS) to provide realtime 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 BMS of the Discover Lithium battery 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 is interrupted between the BMS and Victron inverter-charger, the Victron inverter-charger stops charging until communication is re- established. Figure 1. Example LYNK II with Victron Energy devices
3.2 Compatibility
LYNK II Communication Gateway is compatible with the following:

• AES PROFESSIONAL: DLP-GC2-12V, DLP-GC2-24V, DLP-GC2-48V
• AES RACKMOUNT: 48-48-5120, 48-48-5120-H

Victron Products
Control Panels:

• Cerbo GX
• Color Control GX
• Venus GX

Used in conjunction with:

• Quattro Inverter-Charger
• Multiplus Inverter-Charger
• SmartSolar MPPT

3.3 Minimum Battery System 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. Derive this value 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 demanded by the load attached to the inverter. Match all inverter peak power values with the sum of all battery peak battery current values.
Inverter Peak Amps DC = (Inverter Surge W) / (Inverter Efficiency) / (48V: Low Battery Cut-Off)
Discharge Continuous Amps DC = (Inverter Continuous W) / (Inverter Efficiency) / (48V: Low Battery Cut-Off)

• Turn OFF all devices before connecting cables.
• Do not plug an AEbus RJ45 network cable or terminator into the 10/100 Ethernet port of the LYNK II.
• Do not connect a CAT5 or higher cable from the AEbus, LYNK, or Ethernet ports of the LYNK II to a WAN or MODEM port of a network router.
• Mixing the LYNK Network with other networks may result in equipment malfunction and damage.

NOTICE
Unless specified by Discover Energy Systems, do not connect power electronics directly to the LYNK network or AEbus network.
Refer to the LYNK II Installation and Operation Manual (805-0033) for instructions on network layouts, connections, and terminators of compatible Discover Lithium battery models. Some key points are repeated here for convenience.

• Connect at least one battery to the LYNK Port on the LYNK II.
• A network of batteries will communicate as one battery.
• May connect no more than one network of batteries 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 is internally terminated. AES LiFePO4 batteries are not internally terminated.
When using LYNK II on an AEbus network, install a terminator opposite the LYNK II at the far end of the battery network.
NOTE

• AES LiFePO4 48 V batteries sold before Jan 1, 2020, will not supply power to LYNK II using the network cable connection. An external 13-90 VDC power source connected to the Phoenix 12-pin connector on LYNK II is required for the AES LiFePO4 batteries listed below.
  • 42-48-6650 with a serial number before DET424820275xxxx

LYNK II and AES PROFESSIONAL batteries are both internally terminated. When installing LYNK II with AES PROFESSIONAL batteries, no external termination is required.
LYNK II and AES RACKMOUNT battery modules are both internally terminated. When installing LYNK II with AES RACKMOUNT battery modules, no external termination is required.

5.2 Connecting LYNK II to the VE.Can Network
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. Refer to 4.0 CAN Hardware Termination and CAN Out Pin Configurations.
Insert one end of a CAT5 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.
NOTE
Ensure that the Victron GX device is using firmware version 2.89 or later.

1. VE.Bus: RJ45 socket for connecting to the Victron inverter.
2. 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.

Enabling LYNK II to Communicate with Victron Devices

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.
LYNK ACCESS software for 64-bit Windows 10 is required to configure LYNK II settings for closed-loop CAN communication with Victron Energy devices.
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 to program the inverter-charger 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 OFF and ON the Victron device with the On/Off/Charger Only switch to enable the open-loop settings.
6.1 Victron Open-Loop Configuration
Whenever possible, using a closed-loop configuration is recommended with Discover batteries and Victron devices. However, using 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.
6.1.1 Setting up Open Loop on Victron Devices
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 invertercharger and GX device and then restart the GX device. 6.1.2 Victron Inverter-Charger Open-loop Configuration Procedure

6.1.3 Victron MPPT Charge Controller Open-loop Configuration Procedure
During normal operation, the MPPT charge characteristics are governed by the Victron GX device in a closed-loop configuration based on data and chargerequests provided by the connected Discover Lithium battery.
When closed-loop communication has failed, the MPPT needs to be reset and reconfigured to use open-loop communication. Simply cycling the power does not reset the charger.
To remove the charger from a closedloop system and use it in a system without a BMS:

1. Chargers with LCD display: From the setup menu, change the BMS setting from Y to N (setup item 31). Other chargers: Using VictronConnect, reset the charger to factory defaults.
2. Reconfigure the charger with the recommended open-loop (voltagebased) settings for the Victron MPPT in the table below.

The Victron Connect Bluetooth App is used to configure, monitor, and diagnose Victron MPPT Charge Controller products equipped with Bluetooth.

   Device List > Settings > Services > VE.Can port > CAN-bus profile
   Select VE.Can & CAN-bus BMS (250 kbit/s)

3. Return to the Device List, and the Discover Lithium Battery should now appear as one of the devices.
   Device List NOTE
   If Discover does not appear on the Device List, confirm that the CAT5 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.

4. To confirm that all batteries in the network are communicating with the Victron system, review the actual battery parameters. If multiple batteries are connected, a single entry shows the total limit of all the batteries.

Device List > Discover AES > Parameters 6.3.2 Configurable Closed-Loop Settings
During normal operation, the battery’s charge parameter limits are set by the BMS and communicated by the Victron GX device 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

rated Maximum Charger current, or a lower value if system curtailment is required.
Limit Managed Battery Charge isable| Disable
SVS – Shared voltage sense| Forced off (2)
STS – Shared temperature sense| Forced off
SCS – Shared current sense| ON
SCS status| (Displays the current status)
Controlling BMS| Automatic Selection

1. Limit charge current works across the whole 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.
2. SVS should be set to OFF (Victron support has reported instances of conflicts when SVS is set to ON with a Lithium BMS).

6.3.3 Saving the Configurable Closed-Loop Settings
Device List > Settings> General > Reboot?
After all DVCC menu items have been set, reboot the system. NOTE
To avoid conflicting network information and data, do not use a Victron BMV battery monitor when using the LYNK II Communication Gateway.
