Overview

The XW Pro is a utility interactive inverter/charger with grid-tied, off-grid, and backup power capability. The XW Pro inverters communicate with third party devices, such as a Li-ion Battery Management System (BMS), through the Conext Gateway, InsightHome, or InsightFacility. These devices provide a CAN Bus or Modbus RTU interface for BMS communication. The BMS communication can only work with compatible batteries listed in this document. Li-ion batteries must have an on-board BMS, that, in addition to providing functions of protection, cell balancing, state-of-charge (SOC) and state-of-health (SOH) calculation, also provide a reference for charging voltage and charging current. This reference may be optimized dynamically by the BMS, taking into account the battery SOC, SOH, temperature, or other factors. It is necessary, in such cases, to update the charging characteristics of the XW Pro dynamically as these values change. The operation described in this application note applies to all BMS communication protocols that the system is compatible with.

Supported Architectures

The following diagrams provide a typical system architecture of the Conext Gateway, XW Pro, and a Li-ion battery with BMS. Currently BMS communication is supported for systems with a single XW Pro inverter and optional AC coupled PV inverters. Systems with multiple XW Pro inverters and DC coupled systems with Conext MPPT solar charge controller not currently available with BMS communication (future release). Systems with multiple XW Pro inverters and/or DC coupling with Conext MPPT solar charge controller may be installed without BMS communications subject to the battery vendor approval of the use-case. A Conext Battery Monitor is recommended for these applications to monitor the battery SOC.

Single XW Pro with Single Master BMS (Split-Phase and Single-Phase) with AC Coupling

The XW Pro with compatible Li-ion batteries can be used with AC coupled PV inverters or microinverters. The XW Pro will regulate charging from the AC coupled PV inverters using frequency shifting, based on the battery charging limits and SOC information communicated by the BMS. See the XW Pro AC Coupling Solutions Guide (document part number: 990-6421) for information on the design and installation of AC coupled systems, and be sure to follow all system sizing and other application requirements as described in the document.

Installation and Commissioning

Protection Coordination

WARNING

RISK OF FIRE, ELECTRIC SHOCK, EXPLOSION, AND ARC FLASH
Installation of the battery must be done by qualified and licensed installers following any applicable codes and standards and requirements of local authorities. Installers must ensure that appropriate protection coordination is in place as needed. Failure to follow these instructions can result in death, serious injury, or equipment damage.

Inrush Current

NOTICE

RISK OF BATTERY AND BATTERY INVERTER DAMAGE Always follow the recommended start-up sequence and a minimum number of batteries as described in Appendix A. This is required to avoid excessive inrush current. Failure to follow these instructions can result in equipment damage. Battery-based inverters/chargers, such as the XW Pro, contain an internal DC link which is comprised of capacitors. When the DC breaker between the inverter/charger and the battery is turned On, the inverter/charger draws an inrush current to charge the capacitors. Li-ion batteries contain a supervisory protection inside the BMS which may trigger over-current fault protection to such inrush. For some battery types, multiple battery packs should be connected to the XW Pro inverter simultaneously to share the inrush current between the batteries. This is achieved by closing an installed DC disconnect or breaker at the inverter, after turning on the batteries according to the manufacturer’s instructions.

BMS Setup
Depending on the battery system brand and the number of battery packs, there might be a slave BMS present. XW Pro only supports communication with a master BMS and you must refer to the battery manufacturer’s documentation for information on how to set up slave BMSs to be aggregated into the master BMS.

NOTICE
RISK OF BATTERY DAMAGE
Consult the battery manufacturer’s information for handling details if the battery is completely discharged. Failure to follow these instructions can result in equipment damage.

Wiring Interface
Wire CAN or RS485 interface of the BMS to the 26-pin connector referring to the below diagram. RS485 can be connected to either Port 1 or Port 2 on Conext Gateway. Once the connections are done, power on Conext Gateway and BMS. Refer to the Conext Gateway Owners Guide (Part Number: 975-0806-01-03) for more details on installation.

NOTICE
RISK OF BMS OR CONEXT GATEWAY DAMAGE BMS and Conext Gateway must be powered off while doing the connections. Failure to follow these instructions can result in equipment damage.
