1 Application Note: Grid Settings by Utility Region for the Conext Core XC Series AP-XC-014-EN Revision A Scope This application note lists the default grid settings based on which Utility Region is selected for Conext Core XC Series inverters. For all other information, refer to the Conext Core XC Series Inverter Planning and Installation Manual (part number: ) or the Conext Core XC Series Inverter Operation Manual (part number: ). Table 1 lists the default values for all Utility Region grid qualification and options. s that are read-only are grayed-out in the table. These settings can only be changed by contacting Schneider Electric. Table 2 provides descriptions of all the grid parameters that are defined by the Utility Region setting. s that are read-only are grayed-out in the table. These settings can only be changed by contacting Schneider Electric. You can adjust any settings that are not grayed out. Before making any changes to settings, refer to the Grid Support Guide for Conext Core XC Series Inverters (document number AP-XC-003) for important information about how to define parameters so that the inverter maintains continuous operation and continuous output current during grid-related events.
