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 Gateway’s CAN out PINs to match the CAN in PINs of the power conversion equipment.
• Mount the LYNK II Gateway, 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.
• Ensure all networks are correctly terminated.
• Set the LYNK II Gateway using LYNK ACCESS software to the correct protocol to enable closed-loop communication between the Discover batteries and the power conversion equipment.
• Enable the desired use case and set up user preferences using the power conversion control system.

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 real-time data in a closed-loop configuration to other devices. Closed-loop communication allows inverter-chargers and solar charge controller systems to optimize their 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.
Discover Lithium battery charge and discharge settings in an open-loop configuration are set up manually through the controller for the power conversion device at the time of installation. An open-loop configuration is commonly referred to as a ‘lead-acid drop-in’ replacement configuration.
In a closed-loop configuration, the BMS of the Discover Lithium battery sends 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.

3.3 Minimum Battery System Capacity
Battery charge and discharge rates are managed automatically by the Discover Lithium Battery and the Schneider XW PRO. Using large solar arrays with battery banks that are too small can exceed the operating limits of the battery and possibly lead to the BMS triggering over-current protection. Battery capacity must accept the maximum charge current of the system, or charging must be curtailed below the operating limit of the installed batteries. 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 Value =(Inverter Surge Value) / (Inverter Efficiency) / (48V: Low Battery Cut-Off)

5.1 Networking Discover Lithium Batteries with LYNK II
NOTICE

• 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 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 Battery, power electronics must not be connected directly to the LYNK network or AEbus network.
Refer to the LYNK II Communication Gateway User Manual (805-0033) for detailed instructions on network layouts, connections and terminations for compatible Discover Lithium battery models. Some key reminders are provided in this manual.

• At least one battery must be connected to the LYNK Port or AEbus Port on LYNK II.
• A network of batteries will communicate as one battery.
• No more than one network of batteries may be connected to LYNK II.
• Network termination is required for the system’s proper functioning – note some batteries and devices may auto-terminate.
• LYNK II requires power. There are three possible sources: a 13-90 VDC power supply, AEbus Port, or LYNK Port enabled Discover Lithium batteries or a USB device.
• Discover Lithium batteries must be set to ON to supply power and communicate data with LYNK II.
  AES batteries are not internally terminated. LYNK II is internally terminated. When using LYNK II with an AEbus network, ensure that a terminator is installed at the far end of the battery network opposite LYNK II.

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 HELIOS ESS batteries are both internally terminated. When installing LYNK II with Helios batteries, no external termination is required.
5.2 Connecting LYNK II to the Xanbus Network
Insert one end of a CAT5 communication cable into the LYNK II CAN out port and the other into a Xanbus port of the Xanbus network.
NOTICE
Only one LYNK Gateway device can be connected to the Xanbus network.
NOTICE
The LYNK II CAN Out is internally terminated. No additional termination is required for LYNK II.

Enabling LYNK II to Communicate with Xanbus Devices

When properly connected to a closed-loop network and set to use the Xanbus protocol, LYNK II will transmit real-time parameters from the Discover Lithium battery, including voltage, current, temperature, state of charge and fault conditions to the Xanbus network. LYNK II will also transmit charge voltage and current requests from the Discover Lithium battery to devices on the Xanbus network, such as inverters and solar charge controllers.
LYNK ACCESS software for 64-bit Windows 10 is required to configure LYNK II settings for closed-loop communication with devices on a Xanbus network.
InsightHome or InsightFacility with InsightLocal or InsightCloud access is required to configure the Schneider inverter charger, MPPT Charge Controllers and other Xanbus devices.
Users and installers should be aware that if communication between LYNK II and the Xanbus network is lost, none of the Xanbus devices will display an error or fault warning. The inverters and MPPT charge controllers on the Xanbus network will continue operating with the last battery temperature and charge set-points transmitted by LYNK II. The closed-loop operation of the system will resume if communication is re-established.
Depending on the mode of operation at the time of communication fault and given enough time, the inverter-charger and MPPT charge controllers will eventually put the attached battery into an overcharged or fully discharged state.
When that occurs, either situation will trigger the Discover Lithium Battery BMS to self-protect and disconnect the battery from the system.
To restart communication, the user must intervene by reconnecting the battery network to LYNK II and LYNK II to the Xanbus network. If reconnection is unsuccessful, the batteries and XW PRO inverter should be restarted, and the system converted to an open-loop configuration before resuming operation.
NOTICE
If communication between the LYNK II and the Xanbus network is lost for more than ten seconds, inverters and charge controllers on the Xanbus network will continue
operation with the last battery temperature and charging set-points transmitted by LYNK II. Depending on the mode of operation at the time of communication fault and
given enough time, the inverter-charger and solar charge controllers will eventually put the attached battery into an overcharged or fully discharged state. When that occurs, either situation will trigger the Discover Lithium Battery BMS to self-protect and disconnect the battery from the system.
NOTICE
Discover Lithium batteries and LYNK II do not directly control the inverter’s relay functions, generator starting or other grid-interactive features. These functions are controlled through the programming of the inverter.
6.1 Setting the LYNK II Communication Protocol for Xanbus
