Wiring
Table 2 reflects the recommended wire sizing for the wiring
between the junction box at the beginning of the branch and
the solar disconnect.
The lengths are calculated for a 1.5% maximum voltage
drop. The values take into account the 6' of 14AWG wire
between the individual microinverters.
NOTE - For more detailed information refer to
