Schneider - XW+ Connection Kit and XW+ split phase 120/240 VAC breaker kit
The XW+ Connection Kit and XW+ split phase 120/240 VAC breaker kit contain everything needed to add a second inverter. For a third inverter, use one more Connection Kit and one of the AC breaker kits depending on split or three-phase configuration, plus a pair of 5 ft 4/0 AWG inverter cables (see Wire and Cable). An external transfer switch will be required to enable the inverter bypass function. For four inverters, use two Power Distribution Panels and two Connection Kits. Use the XW+ conduit box to retrofit XW+ inverters into existing systems that already have AC/DC disconnects.
