4. Typical Application Scenarios
Energy storage, lithium battery testing
AC/DC analog power supplies, electronic loads
Energy storage inverters
Peak shaving and valley filling: Store electricity during low-price periods and discharge during peak demand to reduce electricity costs
Uninterrupted power supply: When the grid fails, the system can seamlessly switch to off-grid power supply, ensuring normal operation of the load.
Dynamic capacity expansion: Compensating for short-term power resource shortages and deferring distribution investment
Power quality management, compensating for transient voltage sags in the grid, power factor of loads, and harmonic currents
Can form a hybrid microgrid system
