Bi Directional Inverter special for flow cell battery storage

1. Product introduction

The continuous development of economy has brought about a large amount of energy consumption. The energy crisis and environmental pollution are becoming increasingly serious. The development and large-scale application of new energy has become an inevitable trend of global energy applications. New energy power generation has the disadvantages of low energy density, instability and randomness. The development of energy storage technology can well solve the above problems, making it possible to apply new energy power generation on a large scale. Liquid flow battery is a new type of environment-friendly energy storage battery, which has the advantages of long service life and many times of charging, making it have broad market prospects in energy storage systems. The bidirectional energy storage converter is an energy conversion device between the energy storage battery and the power grid, so the research on the fluid flow energy storage bidirectional energy storage converter is of great significance.

Due to its own characteristics, the new liquid flow battery can be discharged to 0V or the output voltage of the liquid flow battery is 0V because it is not used for a long time, making the 0V black start liquid flow battery a big problem. After research and development by our company, a XNSX series bi-directional energy storage converter is specially customized for the liquid flow battery energy storage system. This product can be connected to the grid or operated independently off the grid with load in combination with the liquid flow battery energy storage system, resulting in a high proportion of load carrying capacity of the system, which can adapt to harsh environments and has high reliability.

3. Product features

 (1) High efficiency and energy saving: the highest efficiency can reach 95%, with a wide voltage input range, which can adapt to other types of batteries such as liquid flow batteries;

(2) Safe and reliable: multiple fault protection mechanism, real-time monitoring, ensuring safe, reliable and stable operation, supporting high and low voltage crossing, rapid power regulation, dynamic power compensation, and strong adaptability of the power grid;

(3) Super load carrying: the virtual synchronous operation technology is adopted, and the response is millisecond level, which can quickly withstand sudden load and equipment startup impact. The maximum short-term impact resistance is more than 3 times of the rated energy storage power, ranking first in the industry;

(4) Smart and friendly: through intelligent control start and stop technology, it supports multiple operation modes, parallel and off grid operation, new energy access, and grid connection of generator sets. In energy storage cooperation, the number of operating units can be adjusted according to the load.

4. Product application

It can be used as a backup power supply for communication facilities, military facilities, hospital buildings, residential areas and other occasions; Its excellent charging and discharging characteristics make it suitable for the power supply of electric vehicles; It can be used for power supply and energy storage in remote areas; At the same time, it can form an energy storage system with photovoltaic power generation and other new energy power generation systems to improve the power quality of the grid and adjust the peak valley difference of power consumption of the grid.
