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 requiring value modification or adaptations. 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 LITE Communication Gateway with compatible Discover Lithium batteries and power conversion equipment are as follows:

Review and confirm equipment compatibility and correct sizing.
Mount the LYNK LITE, and connect the Discover battery communication network to either the LYNK Port or AEbus Port.
Match and connect the LYNK LITE CAN out pins to the CAN pins of the power conversion communication network.
Terminate all networks correctly.
Set up the open-loop configuration parameters on the power conversion equipment.
Set the LYNK LITE 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.
Set up user preferences and enable the use case using the power conversion control system.

3.1 System Overview
The LYNK LITE 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. LYNK LITE also enables the remote monitoring of Discover Lithium battery SOC and data logging of multiple sites using the data monitoring services offered by 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 installation time.
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 finetune 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 uses the charge and discharge settings specified for an open-loop configuration. Discover 805-0059 LYNK LITE Communication

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 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)

INSTALLATION AND CONNECTING LYNK LITE TO THE VE.CAN NETWORK

4.1 Networking Discover Lithium Batteries with LYNK LITE
NOTICE

Turn OFF all devices before connecting cables.
Mixing the LYNK Network with other networks may result in equipment malfunction and damage.

NOTICE
Unless specified by Discover Battery, do not connect power electronics directly to the LYNK network or AEbus network.
Refer to the LYNK LITE Installation and Operation Manual (805-0035) 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 LITE.
A network of batteries will communicate as one battery.
Connect no more than one network of batteries to the LYNK LITE.
Proper system function requires network termination – some batteries and devices may auto-terminate.
LYNK LITE requires power from one of two possible sources (an AEbus/LYNK Port-enabled Discover Lithium battery or a USB device).
Discover Lithium batteries must be set to ON to supply power and communicate with LYNK LITE.

The LYNK LITE is internally terminated. AES batteries are not internally terminated.
When using LYNK LITE on an AESbus or LYNK network, install a terminator opposite the LYNK LITE at the far end of the battery network. LYNK LITE and LITHIUM PROFESSIONAL batteries are both internally terminated. No external termination is required when installing the LYNK LITE with LITHIUM PROFESSIONAL batteries.
4.2 Connecting LYNK LITE to the VE.CAN Network
Ensure that the Victron GX device uses firmware version 2.89 or later before connecting LYNK LITE to the VE.CAN network. Also, ensure the LYNK LITE is configured correctly in the LYNK Access configuration software.
The LYNK LITE CAN out port is an M12 A-Code circular metric connector and the VE.CAN port on the Victron device is an RJ45 connector. An adapter cable is required for the LYNK LITE to connect to the VE.CAN network. Use the optional accessory 950-0060 available from Discover Battery, or make your own. See the diagram below for the proper pin configurations. Discover 805-0059 LYNK LITE
Communication Gateway - Example 3 Attach the M12 connector to the LYNK LITE CAN out port, and insert the RJ45 connector into one of the two VE.CAN ports (A or B) on the back of the Victron device. As the LYNK LITE is internally terminated, the external terminator provided with the GX is not required.

o Insert a terminator in the other VE.CAN port to terminate the network with the LYNK LITE.

ENABLING LYNK LITE TO COMMUNICATE WITH VICTRON DEVICES

When the LYNK LITE is in a closed-loop network using the CANopen protocol, LYNK LITE will transmit real-time parameters from the Discover Lithium battery, including voltage, current, temperature, state of charge, and fault conditions to a Victron device. LYNK LITE also transmits charge voltage and current requests from the Discover Lithium battery to the Victron device.
The Victron inverter-charger defaults to open-loop (voltage-based) settings when there is a break in communication with LYNK LITE. Therefore, as a precautionary measure, it is recommended to program the Victron inverter- charger with the correct voltage-based parameters before setting up the system to operate in a closed-loop configuration.
LYNK ACCESS software for 64-bit Windows 10 is required to configure LYNK LITE settings for closed-loop CAN communication with Victron devices.
5.1 Victron Open-Loop Configuration
You will need the latest firmware on all connected devices. The following presumes familiarity with VE Configure 3 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.
