2. Documentation
This User Manual provides information about the integration of Discover AES Lithium batteries with Sol-Ark devices in a
closed-loop configuration using the AES LYNK Communication Gateway with installed AES LYNK Edge Card for Sol-Ark.
AES battery can be use in Energy Storage System (ESS) for self consumption, grid backup and off-grid applications.These
instructions apply to an off-grid application.
Note that in a Sol-Ark networked system the charging variables will be managed automatically by the AES Battery
Management System (BMS) and the Sol-Ark device. Discharging variables are managed by the set up of the Sol-Ark
inverter.

3. Overview
3.1 System Overview
The AES LYNK Communication Gateway unlocks the full potential of a Discover AES LiFePO4battery by enabling the internal
Battery Management System (BMS) to optimize the charge and discharge configurations of the world’s best inverter/
chargers and solar charge controller systems in a closed loop configuration.
AES LiFePO4 batteries must be set up to work with power conversion and monitoring devices in either an open-loop or
closed loop configuration. AES LiFePO4battery 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 refered to as
a ‘lead acid drop-in replacement’ configuration. 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.
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.
3.2 Minimum Battery Capacity
Battery charge and discharge rates are managed automatically by the AES LiFePO4battery and Sol-Ark 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 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.

4. Installing and Connecting LYNK to the Sol-Ark Network
4.1 Installing the LYNK Edge Card
The LYNK Edge Card for Sol-Ark is a Slot 0 Type which only inserts into the left side slot on the bottom of the LYNK
Communication Gateway.
▲NOTE
• The LYNK Edge Card type to be used is determine by the brand of power
conversion equipment.
• If LYNK Edge Card is in the wrong slot, it will not function.
• If LYNK Edge Card is not firmly seated, it will not function.

▲ CAUTION
HAZARD OF EQUIPMENT DAMAGE
• Do not plug the AEBus RJ-45 cable terminator into the 10/100 Ethernet port
of the LYNK.
• Do not connect a CAT5 cable from the 10/100 Ethernet port of the LYNK to
the WAN or MODEM port of a network router.
• Turn OFF all devices before connecting cables or inserting an Edge Card.
Failure to follow these instructions can damage equipment.
▲ NOTE
• Power electronics are not AEBus devices and should not be connected
to AEBus.

4.2 Connecting LYNK to the Sol-Ark Network
Before connecting LYNK to the Sol-Ark Network ensure that the firmware for all Sol-Ark devices is up to date.
Insert one end of a CAT5 communication cable into the Sol-Ark Edge Card port and the other end into the Sol-Ark inverter CAN
port.
