Step 10: Enphase Energy System Configurations - enphase IQ8 Installation And Operation Manual

A. If required, attach the DC bulkhead adaptors to the
microinverters. Ensure 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: Enphase Energy System configurations

Based on system configuration, Enphase Energy System technology systems include the following
Enphase products:
•
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 storage system provides flexibility to customers to
start small and add capacity incrementally.
•
IQ System Controller 2 The Enphase Energy System includes the IQ System Controller smart
switch with microgrid interconnect 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.
•
Wireless Communications Kit enables direct communication between the IQ Battery,
IQ System Controller, and the Gateway using a 2.4 GHz frequency. The kit is connected to one of
the USB ports on the IQ Gateway.
•
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 Microinverters:
o
IQ8 (IQ8/IQ8+/IQ8M/IQ8A/IQ8H) Series Microinverters and accessories. Enphase
Energy System technology is fully compatible with IQ8 Series Microinverters.
o
IQ Gateway is a communications gateway that can communicate with
IQ8 Series Microinverters, IQ Batteries, and the IQ System Controller. It collects system
performance information and transmits that information over the internet to the Enphase
Cloud. An
