Communication Ports and BTS Port
There are five communication ports and a Battery Temperature Sensor (BTS) port
located on the bottom of the Conext XW+ chassis (as shown above in Figure

• Two Xanbus ports for making network connections between inverters, charge
controllers, and accessories. For more information, see Chapter 4, “Xanbus
Network Installation”.
• Two AC sync ports to connect multiple Conext XW+ Inverter/Chargers in
