Guidelines for network connection
NOTE :
The three-phase inverters require a connection to a neutral phase at any time (only networks with a neutral connection are
supported).
•
For installation on a network without neutral phase, several single-phase inverters can be used.
•
For more information on wiring, refer to Note recommended AC wiring application available on the
SolarEdge SolarEdge website on

•
When connecting several single-phase inverters in a system connected to a three-phase system, the phase
balancing may be required by an operator of public service or network. The balancing of the phases is supported by
SolarEdge inverters. For detailed information, refer to
