Networking DISCOVER Lithium Batteries with LYNK II

NOTICE

EQUIPMENT DAMAGE

Turn OFF all devices before connecting cables.
Do not plug an AEbus RJ45 network cable or terminator into the 10/100 Ethernet port of the LYNK II.
Do not connect a CAT5 or higher cable from the AEbus, LYNK, or Ethernet ports of the LYNK II to a WAN or MODEM port of a network router.
Mixing the LYNK Network with other networks may result in equipment malfunction and damage.

Failure to follow these instructions may result in equipment damage.

NOTE
Unless Discover Energy Systems specifies, power electronics must not be connected directly to the LYNK or AEbus network.

Refer to the LYNK II Installation and Operation Manual (805-0033) for detailed instructions on network layouts, connections, and terminations for compatible Discover Lithium battery models. Some key reminders are provided in this manual.

At least one battery must be connected to the LYNK Port or AEbus Port on LYNK II.
A network of batteries will communicate as one battery.
No more than one network of batteries may be connected to LYNK II.
Network termination is required for the system’s proper functioning - note some batteries and devices may auto-terminate.
LYNK II requires power. There are three possible sources: a 13-90 VDC power supply, LYNK Port-enabled Discover Lithium battery, or a USB device.
Discover Lithium batteries must be set to ON to supply power and communicate data with LYNK II.

AES RACKMOUNT

AES RACKMOUNT Battery Module

Both LYNK II and AES RACKMOUNT Battery Modules are internally terminated. No extra termination is required.

HELIOS ESS

HELIOS ESS Battery

Both LYNK II and HELIOS batteries are internally terminated. No extra termination is required.

NOTICE

TERMINATION REQUIREMENT

HELIOS ESS Batteries prior to serial number DLPHD48B251080001 are supplied with a termination resistor. When setting up closed-loop communication with these HELIOS ESS Batteries, plug the termination resistor into the COM3/COM4 port on the last battery in the LYNK network.

Failure to follow these instructions may result in equipment damage.

NOTE
The HELIOS ESS supports closed-loop communication with the inverter-charger without using the LYNK II Communication Gateway. Connect a CAT 6 or higher straight cable from the HELIOS ESS COM2 port to the inverter-charger’s battery CAN port.
