Chapter 4: Connecting AC and PV Strings to
the Inverter
This chapter describes how to connect the inverter to the AC grid, and to the strings of
modules with power optimizers.
If using an inverter with a DC Safety Unit, refer to the instructions in Connecting the
AC Grid to the Inverter or to the DC Safety Switch on page 33.

Grid Connection Guidelines

In most countries, three phase inverters require neutral connection at all times. In
some countries, the three phase inverters can be connected to delta grids; in other
cases, multiple single phase inverters can be used.
Prior to system installation, refer to:

Countries Supported by the SolarEdge Inverters application note to confirm
compatibility at:
