Connection Unit
This section describes how to connect the inverter to the AC grid, and to the

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:
Three Phase Inverters for Delta Grids application note

Supported Countries application note to confirm
compatibility

confirmation may void the inverter warranty.
For recommended circuit breaker size per model, refer to Determining the Circuit
Breaker Size on page 92.
For more wiring information refer to the SolarEdge Recommended AC
