Chapter 4: Connecting AC and PV Strings to
the Synergy Manager
This section describes how to connect the inverter to the AC grid, and to the PV strings
(also referred to as DC Strings).

Grid Connection Guidelines

NOTE
In most countries, SolarEdge three phase inverters are required by regulation
to have 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:
Three Phase Inverters for Delta Grids application note

delta_grids.pdf.
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 recommended circuit breaker size per model, refer to: Application Note:
Determining the Circuit Breaker
For more wiring information, refer to the SolarEdge Recommended AC Wiring
Application Note , available on the SolarEdge website at

Connecting the AC Grid to the Synergy Manager
The Synergy Manager is provided with two methods of DC connection to the PV strings:
Up to three PV strings connection via cable glands
Up to 12 PV strings connection via MC4 connectors
Figure 16 shows an open Synergy Manager with various types of DC connection of PV
strings.
