With increasing growth in the demand for electricity worldwide and the rapid development of renewable energy sources, the safety of the grid becomes more and more important. Blackout incidents will negatively impact any economy and threaten public safety. Energy storage is regarded as an essential solution to make any power grid more reliable and more flexible, which can be achieved through time shifting, load leveling, smoothing wind/solar output and regulating the frequency etc. Narada energy storage technology relies on patented long-cycle life OPzV/REX series batteries and excellent LiFePO4 lithium battery technology, advanced battery pack technology and intelligent battery management system technology which can offer a wide variety of solutions from large-scale energy storage system solution (ESS, up to MW) to home energy storage system solution (HESS, tens of kilowatts). Narada has completed many successful projects utilizing battery storage solutions from KW to MW in size at home and abroad which covers solar generation, islands generation and also house distributed use.
