Connecting the AC to the Inverter
Refer to Appendix B: Technical Specifications on page 58, for specifications of inverters in different
countries.
Grid Connection Guidelines
For installation on a delta grid without neutral, multiple single phase inverters can be used.
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
When connecting multiple single phase inverters in an installation connected to a three-phase grid,
phase balancing may be required by the utility or grid operator. Phase balancing is supported in the
SolarEdge inverters. For detailed information, refer to the SolarEdge Phase Balancing Manual,
available on the SolarEdge website at
http://www.solaredge.com/files/pdfs/phase_balancing_connection_guide.pdf.
Connecting to AC
Use three wires cable for a single phase connection or five wires cable for three phase connection. The
maximum wire size for the input terminal blocks is 16mm².
1 Turn OFF the AC circuit breaker.
2 Open the inverter cover’s six Allen screws and carefully move the cover vertically before lowering it.
CAUTION:
When removing the cover, make sure not to damage internal components. SolarEdge will not be
held responsible for any components damaged as a result of incautious cover removal.
3 Strip 58 mm / 2.32'' of the external cable insulation and strip 8 mm / 0.32'' of the internal wire
insulation.
Figure 8: Insulation stripping – AC (3-wire cable)
4 Open the AC cable gland and insert the cable through the gland (see Figure 3).
WARNING!
Turn OFF the AC before connecting the AC terminals. Connect the equipment grounding wire
before connecting the AC Line and Neutral wires.
