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.

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.
•
Enphase Wireless communication kit
enables direct communication between IQ Battery, IQ System Controller,
and the Gateway using 2.4 GHz frequency. The kit is connected to one of the USB ports on the IQ Gateway.
•
An Enphase Mobile Connect™
cellular modem is required unless already present to ensure the best performance
of your system. The cellular modem connects to a USB port on the IQ Gateway.
•
For new or retrofit systems with IQ-Series solar microinverters:
o
IQ8 PV
TM
(IQ8/ IQ8Plus /IQ8M /IQ8A /IQ8H-240) series microinverters and accessories
. Enphase
Energy System technology is fully compatible with IQ8 series microinverters
o
IQ Gateway
™,
a communications gateway that can communicate with IQ8 series Microinverters, IQ
batteries, and the IQ System Controller smart switch. It collects system performance information and
transmits that information over the internet to Enphase’s cloud. An IQ Gateway is required for Enphase
Energy systems with IQ-Series microinverters. Note the IQ Gateway is included in an Enphase IQ
Combiner.
