Micro-grid PV system

 

1.     State Grid SidePV Grid-Connected with Energy Storage System


As shown above, the energy storage system is very easy to be mixed together with built grid-connected PV system. The installed capacity has nothing to do with the capacity of battery storage inverter. The whole self-sufficient system is controlled and adjusted by a professional SCADA and it provides a standby power grid which guarantees the power supply for important loads (lighting system, cooling system, communication equipment).

 

1.     Inverter Output Side-- Grid-Connected PV system with Energy Storage System


As shown above, the purpose of this project is to guarantee the power supply for all the loads(household). The capacity of battery storage inverter should be at the same level with the on-grid inverter and satisfy the demands of household loads. The whole self-sufficient system is controlled and adjusted by a professional SCADA. The system capacity needs to be designed precisely based on actual needs. So it can not only guarantee the power supply during power cut, but also extend the hours of electricity service.

 

3.  Grid-Connected PV System With More Energy Sources  

 

As shown above, wind energy and solar energy are two different energy sources. They charge the storage batteries, working with on-grid power system and transmit electricity to every users.  Storage inverter can be used to supply power for the public grid and taken to be standby power supply for users. When the system runs, the storage inverter increases the wind-solar power efficiency and improves the grid stability. So this project is very suitable for application in regions without electricity.
