• AES LiFePO

48 V batteries sold before Jan 1, 2020, will not supply power to LYNK II

using the network cable connection. An external 13-90 VDC power source connected

to the Phoenix 12-pin connector on LYNK II is REQUIRED for the AES LiFePO

batteries listed below.

• 42-48-6650 with a serial number before DET424820275xxxx

LYNK II and HELIOS ESS batteries are both internally terminated. When installing

LYNK II with Helios batteries, no external termination is required.

6. ENABLING LYNK II TO COMMUNICATE WITH SMA SUNNY ISLAND

DEVICES

When properly connected to a closed-loop network and set to use the CANbus

protocol, LYNK II will transmit real-time parameters from the Discover Lithium

battery, including voltage, current, temperature, state of charge, and fault conditions

to the SMA network. LYNK II will also transmit charge voltage and current requests

from the Discover Lithium battery to devices on the SMA network.

LYNK ACCESS software for 64-bit Windows 10 is required to configure LYNK II

settings for closed-loop communication with devices on a CANbus network.

Connect the LYNK II Gateway CAN out port to the 'ComSync In' port on the Sunny

Island inverter-charger using a CAT5 cable. Terminate the ComSync communication

bus at both ends. The LYNK II Communication Gateway is internally terminated.

Sunny Island ComSync In Port RJ45 Pin configuration:

1. Sync1 - reserved
