ENABLING LYNK II TO COMMUNICATE WITH NOARK DEVICES

When properly connected to a managed (closed-loop) network and set to use the NOARK protocol, LYNK II will transmit real-time parameters from the Discover Lithium battery, including voltage, current, temperature, state of charge, and fault conditions to a NOARK inverter-charger. LYNK II will also transmit charge voltage and current requests from the Discover Lithium battery to a NOARK inverter-charger.

LYNK ACCESS software for 64-bit Windows 10 / 11 is required to configure LYNK II settings for managed (closed-loop) CAN communication with NOARK inverter-chargers.

If there is a break in communication between the LYNK II and the inverter-charger for more than ten seconds, the inverter-charger will safely stop operation, so long as the BMS Lithium option is selected and the BMS_Err_Stop parameter is enabled on the NOARK inverter-charger. The inverter-charger will display an F58 BMS Communication Fault if communication is lost. The NOARK inverter-charger will check every five minutes and resume managed (closed-loop) operation if communication is re-established. However, if communication cannot be reestablished, the NOARK inverter-charger will need to be manually converted to a self-managed (open-loop) configuration to resume operation. Refer to the “NOARK Self-Managed (Open-Loop) Configuration” section.

NOTE

In a managed (closed-loop) configuration with the BMS Lithium Batt function enabled, the BMS_Err_Stop parameter must be enabled. If the BMS_Err_Stop parameter is not enabled, the NOARK inverter-charger will continue to operate based on the last communicated battery values. Depending on the mode of operation at the time of communication fault, and given enough time, the NOARK inverter-charger will eventually put the attached battery into an overcharged or fully discharged state. When that occurs, either situation will trigger the Discover Lithium Battery BMS to self-protect and disconnect the battery from the system.
Neither Discover Lithium batteries nor LYNK II directly control NOARK relay functions, generator starting or other grid-interactive features. These functions are controlled through the programming of the NOARK inverter-charger.
