AC Connection
5.3.1 Cable Protection
A sub-distribution panel must be used to connect the Sunny Island 3324/4248 to the
AC loads, a generator or the existing public grid. The sub-distribution panel must be
equipped with appropriate circuit breakers. Be sure to observe all the applicable
regional standards and guidelines.
Typical color codings for the AC installation are:
• Phase conductor (L conductor): brown
• Neutral conductor (N): blue
• Protective ground conductor (PE): green/yellow stripes
The Sunny Island 3324/4248 may only be used in grids where the N conductor is
grounded.
The maximum permissible current that may flow through the AC input of the
Sunny Island 3324/4248 is 56 A.
The neutral conductor (N conductor) is looped through the Sunny Island 3324/
4248, i.e. the N connection terminals of AC output and AC input are connected
inside the inverter.
