The islanding
A new innovation experienced
1ON grid modeManage consumption and production peaks thanks to energy storage system.
2OFF grid modeThanks to PCS, LV grid works alone with local PV production and the batteries energy.

Conclusion
Islanding has just been tested successfully in CARROS
Islanding duration reached 5 hours on October 6th
Islanding is good solution to restore power supply after a grid
outage and to sustain supply during several hours
