This solution addresses the issues of insufficient transformer capacity, long expansion cycles, and high costs during factory production expansion by deploying a lithium iron phosphate energy storage system to achieve virtual capacity expansion. During power peaks, the system automatically discharges to supplement power and prevent tripping; during off-peak periods, it charges to restore. It effectively increases capacity without modifying the transformer. Compared with traditional expansion, it offers fast deployment, lower investment, and flexible scalability, effectively breaking through the power bottleneck of production expansion.
Applicable Scenarios:
Manufacturing factories with insufficient transformer capacity, urgent need for capacity expansion to support production growth, where traditional transformer replacement is costly and time-consuming.
Standard Configuration:
125-522kW / 250-1044kWh low-voltage energy storage cabinet (directly connected to the low-voltage busbar) + intelligent demand management system
Core Strategy:
During production peaks (equipment startup / full-load operation), the energy storage system discharges to prevent transformer overload and tripping.
Demand Charge Optimization:
Controls maximum demand within 90% of the transformer's rated capacity, reducing demand charges by 30%+.
During Grid Fault:
Islanding operation protects and sustains key production lines (≥15 minutes).
Implementation Results:
Equivalent capacity increase: 50%–200%
Installation time: 3 days
Avoids production loss due to expansion downtime
