Chapter 4: Connecting the AC and Strings to
the Connection Unit
This section describes how to connect the inverter to the AC grid, and to the PV strings .
Inverters of different models might be equipped with different sizes/ types of terminal blocks.

Grid Connection Guidelines

NOTE
In most countries, SolarEdge three phase inverters require neutral connection at all times (only grids
with neutral connection are supported).
In some countries, the SolarEdge three phase inverters can be connected to delta grids. For more
information prior to system installation refer to the Three Phase Inverters for Delta Grids application
note,
https://www.solaredge.com/sites/default/files/se_three_phase_inverters_for_
delta_grids.pdf.
and to Supported Countries application note to confirm compatibility:
http://www.solaredge.com/sites/default/files/se_inverters_supported_
countries.pdf; installing without confirmation may void the inverter warranty.
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-
