Schneider Electric Conext XW Pro × Fortress Power eFlex 5.4
Fortress Power's integration guide documents closed-loop communication specifically between its eFlex 5.4 battery and a Schneider Conext XW Pro. The guide routes the eFlex communication through the Conext Gateway and instructs the inverter to use lithium-ion charging with an external BMS, including fault handling for loss of BMS status or state-of-charge information. Follow the current Fortress and Schneider installation documents and gateway wiring requirements before commissioning.
