Step 9: Connect The Pv Module; Step 10: Energize The System - enphase IQ7+ Installation And Operation Manual

NOTE: Minimise the number of unused IQ Cable connectors with three-phase systems. When cable
connectors are left unused on a three-phase system, it creates a phase imbalance on the branch
circuit. If multiple cable connectors are skipped over multiple branch circuits, the imbalance can
multiply.

Step 9: Connect the PV module

WARNING: Electrical shock hazards. The DC conductors of this photovoltaic system are
ungrounded and may be energized.
A. Connect the DC leads of each PV module to the DC input connectors of the corresponding
microinverter.
B. Check the LED on the connector side of the microinverter. The LED flashes six times when DC power
is applied.
C. Mount the PV modules above the microinverters.

Step 10: Energize the system

A. Turn ON the AC fuse or circuit breaker for the branch circuit.
B. Turn ON the main utility-grid AC circuit breaker. Your system starts producing power after a five-
minute wait time.
C. Check the LED on the connector side of the microinverter.
