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 other devices with real-time data in a closed-loop configuration. This allows the world's best hybrid inverters and solar charge controller systems to optimize their 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.

Additionally, LYNK II enables remote monitoring through Discover's LYNK CLOUD web application, allowing access to the battery's state of charge, configuration, and remote troubleshooting over the Internet.

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, Discover Lithium battery charge and discharge settings are set up manually through the controller for the power conversion device at installation time. Refer to the Appendix’s “SAJ Open-Loop Configuration” section.

In a closed-loop configuration, the Discover Lithium battery’s BMS 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 and deliver other functional controls based on battery voltage, temperature, and percent State-of-Charge.
