Energy Storage Applications

· Power Conversion System

11
● Peak-Load Shifting: Optimizes electricity costs for enterprises by storing energy during low-demand periods and utilizing it during peak hours.
● Backup Power Supply: Ensures uninterrupted power for critical loads during outages, with automatic off-grid switching and black-start capabilities.

· Power Conditioning System

12

Photovoltaic Self-Use: Prioritizes solar energy for loads, storing excess power in batteries and providing backup when solar generation is insufficient.

Microgrid Integration: Balances solar energy supply, battery storage, and diesel backup for uninterruptable power in small-scale grids or industrial buildings.

Emergency Power Supply: Supports off-grid operations and emergency black-start functions for critical system protection at power failures.


Power Quality Solutions

· Active Harmonic Filter

16 (1)
● Harmonic Elimination: The harmonic and reactive components of the load current are monitored and compensated in real time, and the power quality is improved by injecting the opposite compensation current.
Real-Time Adjustments: It generates compensating currents with the same amplitude as the load harmonics but of opposite phase, thus canceling the latter. It improves the electrical apparatus' performance and prolongs the life span by maintaining a non-pulsating power supply.

· Static Var Generator

14 (1)

● Reactive Power Compensation: PF0.99 grade is achieved with over 95% efficiency, offering dynamic voltage stabilization and power factor improvement.

Instantaneous Response: Total response time is less than 50 microseconds, ensuring consistent voltage control.

Flexible Applications: Diverse applications, from industrial processes to power distribution networks.

· Advanced Static Var Generator

3

●Reactive power and harmonic compensation: ASVG not only compensates reactive power, but also supports low-order and small-capacity harmonic compensation to achieve reactive power compensation and harmonic control.

●Three-phase balance regulation function: ASVG has three-phase unbalance regulation function, which can generate reactive current and low harmonic wave to meet the requirements by controlling the inverter, so as to achieve the purpose of reactive power compensation and harmonic control.

Micro Inverter

· Micro Inverter

1
Maximized Solar Power Output: Each panel operates independently, optimizing performance even in shaded areas.
●Energy Independence & Grid Contribution: Generate clean energy and feed excess back into the grid, reducing costs and earning credits.
●Seamless Integration with Home Systems: Works with battery storage and smart home solutions for efficient energy management.
