3. 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.

6
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.

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 ContinuousW) / (Inverter Efficiency) /

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.
Figure 2. AES LiFePO4 Mobile Industrial Battery
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.
