GSL-CESS-125K261 Liquid-cooled cabinet High-voltage battery system
Multi-Scenario Application Value
Peak-Valley Arbitrage
Leverage electricity price differences: charge during off-peak hours and discharge during peak hours to reduce overall electricity costs and enhance investment returns.
Demand Management / Dynamic Capacity Expansion
Release stored energy during peak demand to flatten the load curve, avoiding transformer overload and peak demand charges, thereby saving operational costs.
Backup Power
Millisecond-level switching to critical loads (e.g., production lines, data centers, communication equipment) during grid anomalies or outages, ensuring production continuity and business security.
Renewable Energy Consumption
Pair with PV systems to store excess daytime generation for use at night or on cloudy days, increasing the self-consumption rate to over 80% and reducing losses from low-price feed-in of surplus power.
Demand Response & Peak Shaving
Respond to grid dispatch, participate in peak shaving and valley filling, providing grid ancillary services while earning subsidy revenues.
Anti-Reverse Power Flow Function
Monitor load power in real-time, dynamically adjust system output to ensure zero power feedback to the grid, meeting grid connection safety and compliance requirements.
