ENABLING LYNK II TO COMMUNICATE WITH SOL-ARK DEVICES
When properly connected to a closed-loop network and set to use the Sol-Ark 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 Sol-Ark inverter. LYNK II will also transmit charge voltage and current requests from the Discover Lithium battery to a Sol-Ark inverter.
LYNK ACCESS software for 64-bit Windows 10 / 11 is required to configure LYNK II settings for closed-loop CAN communication with Sol-Ark inverters.
Users and installers should be aware that if communication between the LYNK II and the inverter is lost for more than ten seconds, the inverter will safely stop operation, so long as the BMS Lithium Batt and the BMS_Err_Stop parameters are both enabled on the Sol-Ark inverter. The inverter displays the F58 BMS Communication Fault when communication is lost.
The Sol-Ark inverter will check every five minutes and resume closed-loop operation if communication is reestablished. However, if communication cannot be re-established, the Sol-Ark inverter will need to be manually converted to an open-loop configuration to resume operation. So, as a precautionary measure, it is recommended that the Sol-Ark inverter be programmed with the correct voltage-based open-loop parameters before setting up the system to operate in a closed-loop configuration.
If the BMS Lithium Batt parameter is disabled and the Use Batt V Charged parameter is enabled, the Sol-Ark inverter will operate in an open-loop configuration using voltage-based parameters.
