3. Overview
3.1 System Overview
The AES LYNK Communication Gateway unlocks the full potential of a Discover AES LiFePO4 Battery
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 LiFePO4 battery 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
referred to as a ‘lead acid drop-in replacement’ configuration. For information on Open Loop set up
with Victron devices please visit the Discover Battery web site www.discoverbattery.com » Solutions »
Solar » Resources » Application Note »> Discover-AES-Lithium-Open-Loop-Integration-Victron-Energy.
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. These instructions are for a Closed Loop configuration.
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 LiFePO4 Battery and
Victron CCGX 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 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 Configuring Victron Products
4.1 Powering Up Equipment
Make sure none of the Discover AES communication cables are installed.
Connect MultiPlus/Quattro, GX device, MPPT etc to the batteries in a safe way in accordance
with the local electrical requirements/code.
Connect all Victron communication cables at this time.
Turn ON the Discover AES Battery press and hold switch on the battery/batteries for 2-3
seconds.
Turn on Multi/Quattro
If this is the initial set up of the MultiPlus or Quattro apply power to Victron Equipment and update
firmware to the devices listed to:
MultiPlus / Quattro - version 459 or later.
GX device to include Color Control/ Venus/Octo/Cerbo- version 2.40 or later.
VE.Direct MPPT - version 1.42 or later.
This will also presume the VE Bus has already set up if required, such as:
Dual Phase/Split Phase 180 degrees out
3 Phase
4.2 VE.Configure Settings
This section presumes familiarity with VEConfigure software. These settings are for an off-grid
application. These parameters once set will become the default values used if communication with
the AES battery is interrupted for some reason. During normal operation the charge characteristics
are governed automatically by the CCGX via DVCC, with instructions from the connected AES battery.
However it is necessary to set the discharging parameters for DC input low shut-down found under
the Inverter Tab. After setting the parameters, ‘send’ all parameters to the inverter and CCGX. Restart
the CCGX after completion.
If the system is in a off-grid setting the max charge current would be dependent on generator size,.
Also keep in mind the settings below are for 1 unit only. If the system is a multiple inverter/charger
configuration, determine the max charge current for all units installed does not exceed the Discover
battery charge current limit .
