HELIOS ESS Closed-Loop Communication - Supported Inverters

NOTE

If the inverter-charger you are connecting to the HELIOS ESS battery is not listed here, you may alternatively use the LYNK II Gateway for managed (closed-loop) communication. Otherwise, managed (closed-loop) communication may not be supported with your particular device.

However, you can connect the inverter-charger to HELIOS ESS batteries in a self-managed (open-loop) configuration.

Refer to How to Calculate Minimum Battery Sizing and calculate the minimum number of batteries required for your energy storage system. Depending on how the system is used, to optimize it, you may require more than the minimum number of batteries.
Follow the instructions to set the inverter-charger to a self-managed (open-loop) configuration.
Connect and operate the inverter-charger and HELIOS ESS batteries as described in this manual.

The HELIOS ESS battery supports closed-loop communication using two different methods:

Direct (without LYNK II Gateway) using the Pylon protocol.
LYNK II Gateway.

The following table identifies the closed-loop communication methods available to supported inverter-chargers.
