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 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.

• Review and confirm equipment compatibility and correct sizing.

• Configure the LYNK II Communication 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.

• Terminate all networks correctly.

• 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.

• Set up user preferences and enable the use case using the power conversion

control system.

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. This

configuration allows hybrid inverter-chargers and solar charge controller systems

to optimize 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 SMA Sunny Island Inverter-

Chargers in a closed-loop configuration. In a closed-loop configuration, the BMS of

the Discover Lithium battery sends battery status over a network data connection

with the SMA Sunny Island Inverter-Charger. The SMA Sunny Island Inverter-

Charger uses the Discover Lithium battery BMS data to finetune the output of the

charger and deliver other functional controls based on battery voltage, temperature,

and percent State-of-Charge.

If communication is interrupted between the BMS and SMA Sunny Island Inverter-

Charger, after about 1 minute the power conversion device throws a fault (F952

MalfunctionExtBMSTimeout). Once communication is re-established, power

conversion device operations resume.

• SMA Sunny Island Inverter-Charger cannot be operated in an open-loop

configuration with Lithium batteries based on voltage-only charge settings.
