Enphase IQ8 Install and Operation Manual

IQ8 / IQ8+ / IQ8M / IQ8A / IQ8H Micro Installation and Operation

F. Attach the terminated cable end to the PV racking with a cable clip

or tie wrap so that the cable and terminator. Do not touch the roof.

WARNING: The terminator cannot be re-used. If you unscrew the

nut, you must discard the terminator.

Step 8: Complete Installation of the Junction Box

A. Connect the Enphase IQ Cable into the junction box.

B. Refer to the wiring diagrams on page 47 for more information. Wire colors are listed in the following table.

Step 9: Connect the PV Modules

WARNING: Electrical shock hazard. The DC conductors of this photovoltaic system are ungrounded and

may be energized.

A. If required, attach the Enphase DC bulkhead adaptors to the

microinverters. Make sure they are fully seated. Do not reverse the

adaptor connections.

B. Connect the DC leads of each PV module to the DC input

connectors of the corresponding microinverter.

C. Check the LED on the connector side of the microinverter. The LED

flashes six times when DC power is applied.

D. Mount the PV modules above the microinverters.

Step 10: Energizing Enphase Energy System & Configurations

IQ8 Micro based PV systems can operate in grid-tied mode (solar only) out of the box. Additional modes of operation

could be enabled when connected with other Enphase Energy System products.

Following are common system configurations possible with The Enphase Energy System using IQ8 PV (IQ8/ IQ8Plus

/IQ8M /IQ8A /IQ8H-240) microinverters. IQ8H-208 supports split phase, 208V in grid-tied mode configuration only.

− Solar Only

− Sunlight Backup

− Home Essentials Backup

− Full Energy Independence

Based on System configuration Enphase Energy system technology systems include following Enphase products -

• Enphase IQ Battery system is an all-in-one AC coupled storage system that includes embedded, grid-forming

multimode microinverters. You can connect multiple IQ Battery systems to maximize potential backup for homes.

The IQ Battery 3 storage system provides flexibility to customers to start small and add capacity incrementally.

• Enphase IQ System Controller R2 The Enphase Energy System includes the IQ System Controller™ smart switch

with Microgrid Interconnection Device (MID) capability, which consolidates interconnection equipment into a single

enclosure and streamlines grid-independent capabilities of PV and storage installations by providing a consistent,

pre-wired solution for residential applications. Along with MID functions, it includes PV, storage, and generator input

circuits. It allows IQ Battery storage systems to form an intentional island (per IEEE 1547.4 definition) and contains

a neutral-forming transformer (NFT) to enable 120/240 V operation in backup mode.
