Closed-Loop Communication Without LYNK II Communication Gateway

Closed-loop communication without the LYNK II Communication Gateway is available with many brands of inverters. Refer to the HELIOS ESS Installation and Operation Manual (805-0090) to see if your inverter is supported.

Connect a CAT6 or higher communication cable from the inverter to the first battery, then the first battery to the second battery, and then the second battery to the third battery. If required, terminate the LYNK network at the last battery in the system.
