Schneider Electric Inverter Configuration (Closed Loop Without LYNK II)

NOTICE

EQUIPMENT DAMAGE

When operating in a closed loop, the BMS communicates the internal battery temperature with Schneider Electric devices. Remove any temperature sensors from inverters or charge controllers so they do not override or conflict with the BMS.

Failure to follow these instructions may result in equipment damage.

The HELIOS ESS supports closed-loop communication with the Schneider Electric XW PRO inverter-chargers listed in the Closed-Loop Communication with Inverters table in the HELIOS ESS Closed-Loop Communication topic.
To enable communication between the inverter and batteries:

Connect a CAT6 or higher straight cable to the HELIOS ESS COM2 port, split the wires, and connect them to the corresponding CAN pins on the Insight device.

Wiring

This describes how to wire the HELIOS ESS COM2 (CAN Port) to the Schneider Electric Insight device.

Use a CAT6 or higher cable to connect the pins on the HELIOS ESS CAN port to the CAN pins of either the 12-pin connector of InsightHome or the 26-pin connector of InsightFacility.

Using your computer, log in to the InsightHome or InstightFacility device and configure the parameters for Schneider Electric devices.
Specify settings according to the following instructions.

Setting up the Insight Device

Updating Schneider Device Firmware

Ensure that all devices have up-to-date firmware.

Update the firmware of the InsightHome or InsightFacility.
1. Setup > Configuration
2. From Firmware Upgrade, click Upload Package and install the latest firmware file.
Update the firmware of the XW PRO.
1. Devices > Inverter/Chargers > Firmware
2. Click Upgrade and install the latest firmware file.
Update the firmware of the MPPT controller.
1. Devices > Charge Controllers > Firmware
2. Click Upgrade and install the latest firmware file.

Setting the Insight Device to use BMS Configuration

Set up InsightHome or InsightFacility to use the BMS Configuration with InsightLocal.

This setup menu automatically configures the XW PRO according to the selected battery model and the number of batteries in the system. It also configures the XW PRO’s Charge Cycle to External BMS, the Battery Type to Li-ion, and SOC Control to Enabled. MPPT Solar Charge Controllers connected to the system will also be automatically configured with the correct charge voltage.

NOTE
The Schneider Electric devices and batteries must be connected together to proceed with configuration. XW PRO, MPPT Solar Charge Controllers, and batteries must have the same association and unique device numbers. Setting changes are not implemented until they are saved. Ensure that updates to Settings are saved by clicking on the APPLY button.

> Device Association

InsightLocal > BMS > Configuration (Advanced) > Device Identification

From the Device Association drop-down menu, select the appropriate battery.
Click APPLY.

NOTE
Complete the Device Association before continuing with BMS Setup.

> BMS Setup

InsightLocal > Setup > BMS Setup

InsightLocal > BMS Setup	System Value
Battery Type	Select the appropriate Discover Lithium battery model. NOTE: If the battery model is not listed, the Schneider Electric team may still be adding it to their software. As an alternative, select an EG4 battery model and configure the Insight settings that follow.
Quantity	Specify the number of lithium batteries
Match MPPT Voltage to BMS	Set to ENABLED
MPPT Voltage Offset	Set to 1.0 V. Adjust if batteries do not fully charge or the battery’s overvoltage protection is engaged. Lowering this value brings the charge controller’s tolerance for the inverter voltage delta closer. For example, 1 V means the charge controller operates at 1 V less than the readings on the inverter.

Verify Battery Network Connections

Review the following steps to verify that all batteries communicate with the LYNK II Gateway and the Schneider system.

Devices > Inverter/Chargers > Configuration (Advanced) > Battery Settings

If the connection was successful, the listed Battery Bank Capacity is as follows:

Battery Settings	HELIOS ESS (52-48-16000)
Battery Bank Capacity	314 Ah × number of batteries

If the connection is unsuccessful, check that the Discover LYNK/AEbus network is correctly terminated and that there is no damage to the network cabling, terminators, and connectors. Confirm all batteries have the same firmware revision. Rectify any problems and verify again.

NOTE
Discover batteries are visually represented by a Conext Battery Monitor image when viewed on InsightLocal or InsightCloud.
