Monitoring Platform of Self-Produced and Used


  • Solar energy self-generated and used：When the output of solar energy exceeds the self-consumption, the electricity can be exported to the grid otherwise lost, or installed energy storage system to store electricity.
  • Reduce electricity bills and electricity consumption.
  • 0-export: power output <= power consumption (Pinv <= Pload)

0-Export

Case Study

Alkion, a large oil depot in italy that used SolarEdge.

  • When the AC power is turned off, SafeDC™ can reduce the DC voltage of each module to 1V, therefore it can protect the installer, maintenance personnel, and First responder(firefighter) from the electrocution during the work.
  • Reduce the risks from arc fault detection/interruption.
