Closed-Loop CANbus Communication
Closed-Loop CANbus Communication with the LYNK II Gateway
The AES 210HV Cabinet ships with a factory-installed LYNK II Communication Gateway. Using CANbus, the LYNK II Gateway connects the BMS of the battery with the battery BMS ports of the Sol-Ark 60K-3P-480V and performs the following.
Establish battery limits (charge/discharge current, voltage, temperature) so the inverter always operates within safe parameters.
Push live state-of-charge and operating data to the inverter for accurate power-flow and alarm handling.
Continuously adjust the inverter’s charge profile in response to real-time cabinet conditions.
System Layout | LYNK II Connections | Result |
|---|---|---|
1x AES 210HV 1× 60K-3P-480V | Connect the LYNK II CANout to the inverter BMS 1 (BMS 2 open). | A single closed-loop pathway. |
2× AES 210HV 1× 60K-3P-480V | Utilize one LYNK II per cabinet. Connect the first LYNK II CANout to BMS 1 and the second LYNK II CANout to BMS 2. | The inverter uses each cabinet as an independent battery and shares the power evenly. |
1x AES 210HV 2× 60K-3P-480V | Requires two LYNK II Gateways. Connect the LYNK II CANout to the inverter BMS 1 (BMS 2 open) in each inverter. | Each inverter has its own closed-loop connection and operates as if it is connected to a separate battery. |
NOTICE |
|---|
EQUIPMENT DAMAGE Connect the Sol-Ark inverter’s BMS1 and BMS2 ports only to the CAN port on the LYNK II Gateway using a standard CAT5e or higher cable. Do not connect the inverter's BMS ports directly to the J3 or J4 ports on the AES 210HV High Voltage Box, as this can damage the inverter. Failure to follow these instructions may result in equipment damage. |
