8 (L+N)/24 (3L+N)
For IQ Cable with 2.5 mm
using a 1.25 safety factor, 16 A per phase is calculated
as the maximum current according to IEC 60364. The
safety factor applied may vary based on local
regulation or best practice, also upon the
characteristic the OCPD selected.
8 (L+N)/11 (3L+N)
Centre feeding is the best practice. These design limits
should ensure voltage rise and line conductor
resistance on the IQ Cable are maintained within
acceptable limits. In locations with a risk of high grid
voltage at the point of connection, it may be
necessary to decrease the maximum number of
microinverters on the IQ Cable section by as much as
50%.
