Built for Reserve Markets and Grid Stability

FCR-Ready

Delivered with Nordic Booster's pre-qualified software for FCR-N and FCR-D in the Nordic Synchronous Area. Optimized for continuous reserve market participation with fast response times.

🔋

BRP Protection

Ensures actual production matches planned production by storing and releasing energy as needed. Reduces imbalance costs and protects revenue for Balance Responsible Parties.

🔌

Grid-Forming Technology

Sungrow's Stem-Cell Grid-Forming Tech maintains stable operation under variable grid conditions. Independent rack control eliminates bottlenecks and increases total discharge capacity.

🛡️

ArcDefender™ Safety

Industry-leading arc detection with rapid shutdown. Separated electrical and battery cabinets prevent thermal propagation, with integrated fire suppression and fault zone isolation.

🌡️

Intelligent Liquid Cooling

Advanced liquid cooling system optimizes auxiliary power consumption and ensures uniform cell temperature for longer life and higher capacity utilization.

📡

Remote Monitoring via Chargio

Connects to the Chargio platform for remote control, monitoring, and optimization of production plans, reserve markets, and energy services.

BRP Safety Net

FlexBooster acts as a safety net for Balance Responsible Parties. When production deviates from the plan, the battery is automatically activated to cover the difference in real time.
