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. 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 CAN out pins to match the CAN in pins of the power conversion equipment.
  • Mount the LYNK II, connect the 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.
  • When commissioning the power conversion equipment, select the Discover Energy Systems battery model and the battery’s LVD-LVR Profile.
  • Set the LYNK II 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.

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. 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 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 time of installation. 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 fine-tune the output of their charger as well as deliver other functional controls based on battery voltage, temperature, and percent State-of-Charge. If communication between the BMS and Morningstar power conversion device is interrupted, the power conversion device faults after a few seconds and stops the charging process. If communication between the BMS and the Morningstar power conversion device is restored, the fault is cleared and charging continues.DISCOVER-ENERGY-
