Application scenario:
1. Mobile energy storage
The mobile energy storage rescue system consists of PCS, energy storage battery and straight charging pile. It can recharge new energy electric vehicles, and it can also provide power rescue for important places and emergency sites.
2, cut peak fill valley, transformer capacity
The energy storage system consists of PCS and energy storage battery. When the power supply valley is in the grid, the power is collected from the grid and stored in the battery; During the peak of power consumption in the grid, the battery is discharged to the grid by the load consumption, reducing the power from the grid. Thus to achieve the role of peak cutting and valley filling, saving electricity costs. In addition, PCS reduces the power taken from the grid and reduces the power transformer load when releasing power to the grid.
3. Ac/DC microgrid
PCS, DCDC, energy storage batteries, photovoltaic, wind power and other new energy are combined to form a microgrid, and the new energy, energy storage batteries, and power grid are rationally configured to achieve flexible and efficient use of distributed power sources.
4, multi-port energy router
By PCS, DCDC, energy storage battery, photovoltaic, wind power and other new energy and load according to the needs of customers into a multi-port energy router. Multi-port energy router can access a variety of different voltage levels of load, can be easily incorporated into a variety of distributed energy, each port can plug and play, convenient and fast.
