Grid protection relay for XOLTA battery systems

XOLTA battery systems, such as BAT-80, feed power into the grid as decentralized energy sources. To maintain grid stability, voltage and frequency must remain within acceptable limits. Every decentralized energy system requires grid and system protection, also referred to as NA SchutzClosed Synonym for "grid and system protection" and "NS protection". or NS protection.

The XOLTA inverters are pre-configured to comply with the specific grid codes of their respective country or region, for example, frequency response settings. However, to achieve full grid code compliance, an external, standalone grid protection relay is required for the entire battery system installation. This relay continuously monitors voltage and frequency at the point of common couplingClosed The connection point between a generating facility (e.g., a battery system) and the utility grid, where power exchange occurs. (PCC), acting as a safeguard against grid instability.

If grid parameters deviate from permitted thresholds, the grid protection relay will automatically disconnect the battery system to prevent potential disruptions. Once grid conditions stabilize, the relay safely reconnects the system, ensuring seamless operation while maintaining regulatory compliance.
