Commercial Energy Storage Solutions

   Commercial Energy Storage Overview
    Following the construction of smart grid, the amount of renewable energy in overall power generation continues to increase, the end user demand for energy storage is rising, and energy storage technology has became an necessary part of electric power systems. Meanwhile, enterprises, factories and commercial buildings has large load quantity, with load demand fluctuates frequently and/or has big step price between peak and valley period, so it is very important for these places to setup energy storage systems, which can implement peak shaving and valley filling, reduce the overall use of electricity and save cost. It also can be used as backup power for emergency when grid power failed. In addition, the energy storage system can smooth the impact of large power load and delay power distribution facility expansion demand.

   Typical Application
    Peak shaving and valley filling, reduce electricity charge.
    Backup power for emergency situations.
    Control load fluctuation, reduce power distribution facility demand.
    Retired lithium power battery reuse.
