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 220/230/480V delta grids. For more information prior to system
installation refer to:

Supported Countries application note to confirm
compatibility

; installing without
confirmation may void the inverter warranty.
