Commercial PV-ES Hybrid System Solutions

   Overview
With the increase of PV power in the overall energy supply market, independent PV power characteristics like random, intermittent and volatility affect the safety and stable operation of the grid. In order to ensure safety, stability and power quality of micro grid systems which contains PV system, it's necessary for distribution PV power generator to setup energy storage facilities to stabilize the operation of micro grid system and consume as much PV power as possible locally, to improve PV self-consumption, play the role of peak shaving and valley filling, also reduce electricity bills.
   Applications
    Peak shaving and valley filling, reduce electricity charge.
    Backup power for emergency situations.
    Improve PV self-consumption.
    Retired lithium power battery reuse.
