Enabling LYNK II to Communicate with Schneider Electric Devices

When properly connected to a closed-loop network and set to use the Schneider BMS 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 Schneider Electric inverter. LYNK II will also transmit charge voltage and current requests from the Discover Lithium battery to the Schneider Electric inverter.

LYNK ACCESS software for 64-bit Windows 10 / 11 is required to configure LYNK II settings for closed-loop communication with Schneider Electric devices on the network. InsightHome or InsightFacility with InsightLocal or InsightCloud access is required to configure the XW PRO and MPPT Charge Controllers, as well as other Schneider Electric devices.

If communication between the LYNK II and the XW PRO is lost, it will display either a Fault or a Warning.

FAULT

When the Schneider Electric communication is to fault, the XW PRO will go offline.
The MPPT Solar Charge Controllers will continue to operate in the Last State before communication was lost. The closed-loop operation of the system will resume if communication is re-established.

WARNING

When the Schneider Electric communication is set up to display a warning, the XW PRO will continue operating with the measured battery voltage and the Comms Lost Battery set points specified with InsightHome or InsightFacility.
The MPPT Solar Charge Controllers will continue to operate in the Last State before communication was lost. The closed-loop operation of the system will resume if communication is re-established.

To restart communication, the user must intervene by reconnecting the battery network to LYNK II and LYNK II to the Schneider Electric network. If reconnection is unsuccessful, restart the batteries and the XW PRO inverter, then convert the system to an open-loop configuration before resuming operation. Refer to Schneider Electric Open-Loop Configuration.
