SolarEdge SE Series - Connecting AC Grid and PV Strings

Connecting the ACGrid to the Inverter or to the DC
Safety Switch
Use AC cable in a diameter of 19 mm to 28 mm. For three phase connection, use a
standard cable with five wires (L1,L2,L3 + N + PE) or three wires (L1,L2,L3 + PE) cable .
The cross section of the conductor of the wires must be 4 mm² to 16 mm².
When using a stranded wire, the use of ferrule is at installer discretion.
For more wiring information refer to the SolarEdge Recommended AC
Wiring Application Note , available on the SolarEdge website at
http://www.solaredge.com/files/pdfs/application-note-recommended-
wiring.pdf.
