The Enphase IQ System Controller 3M supports a 240 V L-L/
120 V L-N split-phase supply (i.e., two phases that have a phase
angle of 180°). For use with grid supplies other than a split-phase,
an appropriate external transformer must be provided to convert
the incoming supply from the utility to a split-phase supply.
Sizing of the transformer must be done per system requirements
and must be sufficient to cover the load and distributed energy
resource (DER) requirements. Local and national electrical
codes, as well as utility interconnection requirements, must
be met by the installer when using an external transformer.
