Installing the grid protection relay

This chapter outlines the installation process for grid protection relays in XOLTA C&I battery systems. It specifies recommended devices (ABB CM-UFD.M31/M31M and Schneider iCT contactors), explains wiring schematics for various market scenarios (with and without LVRTClosed Short for "low voltage ride through". LVRT is the ability of an electrical device - typically a wind turbine or solar inverter - to stay connected to the grid during short periods of low voltage, such as those caused by faults or disturbances. The purpose is to support the grid by remaining online and helping restore normal conditions.), and details component requirements based on system size. The chapter includes single-line diagrams and connection legends to support correct and compliant installations.
