| ECOLTO-102KWhESS |
| The 102KWh Energy storage system solution |
| 1)Quick Details |
| 102KWh Energy storage system solution |
| 2)Features |
| As LiFePo4 battery energy storage technology is relatively mature, large capacity, safe and reliable, low noise, strong environmental adaptability, easy to install and other advantages, battery is commonly used to store electric energy in energy storage system. |
| 3)Application |
| Battery energy storage system (BESS) is a system which uses lithium battery as energy storage carrier, stores electric energy in a certain time and supplies electric energy in a certain time, and the electric energy provided has smooth transition, peak shaving and valley filling, frequency and voltage regulation and other functions.Energy storage system can realize energy transfer and promote the application of new energy; Micro grid can be established to provide power for non power areas; It can adjust peak and frequency to improve the stability of power system. |
