StorEdge™ On-Grid Solution

SolarEdge’s StorEdge DC coupled storage solution can be used to increase energy independence for homeowners by utilizing a battery to store and supply power as needed. To optimize self-consumption, the battery is automatically charged and discharged to meet consumption needs and reduce the amount of power purchased from the grid. The solution is based on a single inverter for both PV and storage. Existing SolarEdge systems can be upgraded to the StorEdge solution. 
The SolarEdge StorEdge solution is compatible with the RESU7H and RESU10H batteries after a firmware upgrade. The table below shows the compatibility of the different StorEdge interfaces with LG Chem batteries.
