How the Enphase IQ Microinverter for ACM Works
The Enphase Microinverter maximizes energy production by using a sophisticated Maximum Power Point
Tracking (MPPT) algorithm. Each Enphase Microinverter is individually connected to one PV module in
your array. This configuration enables an individual MPPT to control each PV module, ensuring that
maximum power available from each PV module is exported to the utility grid regardless of the
performance of the other PV modules in the array. While an individual PV module in the array may be
affected by shading, soiling, orientation, or PV module mismatch, each Enphase Microinverter ensures
top performance for its associated PV module.
System Monitoring
Once you install the Enphase IQ Envoy and provide an internet connection through a broadband router or
modem, the Enphase IQ Microinverters automatically begin reporting to Enlighten. Enlighten presents
current and historical system performance trends and informs you of PV system status.
Optimal Reliability
Microinverter systems are inherently more reliable than traditional inverters. The distributed nature of a
microinverter system ensures that there is no single point of system failure in the PV system. Enphase
Microinverters are designed to operate at full power at ambient temperatures as high as 65C (150F).
Ease of Design
PV systems using Enphase Microinverters are very simple to design and install. You will not need string
calculations or cumbersome traditional inverters. Low voltage DC wires connect from the PV module
directly to the co-located microinverter, eliminating the risk of personnel exposure to dangerously high DC
voltage.

Planning for Microinverter Installation
The microinverter housing is designed for outdoor installation and complies with the IP67 Outdoor
environmental enclosure rating standard:
IP67 rating definition: Indoor or outdoor use primarily to provide a degree of protection
against hose-directed water, the entry of water during occasional temporary submersion at a
limited depth, and damage from external ice formation.
The Enphase Q Cable is available with connector spacing options to accommodate installation of PV
modules in portrait or landscape orientation. For Enphase Q Cable ordering information, see “Enphase Q
Cable Planning and Ordering” on page 28.
Planning the Racking
Plan the racking position with the Microinverter in mind. Ensure that the racking does not interfere with
the microinverter and its connectors.
Grounding Considerations
The Enphase Microinverter models listed in this guide do not require grounding electrode conductors
(GEC), equipment grounding conductors (EGC), or grounded conductor (neutral). Your Authority Having
Jurisdiction (AHJ) may require you to bond the mounting bracket to the racking. If so, use UL2703
hardware or star washers. The microinverter itself has a Class II double-insulated rating, which includes
ground fault protection (GFP).
Branch Circuit Capacity
Plan your AC branch circuits to meet the following limits for maximum number of microinverters per
branch when protected with a 20 amp (maximum) over current protection device (OCPD).
Maximum* IQ Microinverters per AC branch circuit

Wire Lengths and Voltage Rise
When planning the system, you must select the appropriate AC conductor size to minimize voltage rise.
Select the correct wire size based on the distance from the beginning of the AC branch circuit to the
breaker in the load center. Enphase recommends a voltage rise total of less than 2% for the sections from
the AC branch circuit to the breaker in the load center.
Enphase provides guidance about choosing wire size and maximum conductor lengths in the Voltage
Rise Technical Brief at enphase.com/support. Refer to this brief for voltage rise values in Enphase
Q Cables and on how to calculate voltage rise in other wire sections of the system.
Standard guidelines for voltage rise on feeder and AC branch circuit conductors might not be sufficient for
microinverter AC branch circuits that contain the maximum allowable microinverters. This is due to high
inherent voltage rise on the AC branch circuit.
Best practice: Center-feed the branch circuit to minimize voltage rise in a fully-populated
branch. This practice greatly reduces the voltage rise as compared with an end-fed branch.
To center-feed a branch, divide the circuit into two sub-branch circuits protected by a single
OCPD.
Lightning and Surge Suppression
Enphase Microinverters have integral surge protection greater than most traditional inverters. However, if
the surge has sufficient energy, the protection built into the microinverter can be exceeded, and the
equipment can be damaged. For this reason, Enphase recommends that you protect your system with a
lightning and/or surge suppression device. In addition to having some level of surge suppression, it is also
important to have insurance that protects against lightning and electrical surges. Enphase has tested the
devices in the following tables.
Residential
Commercial
•Citel DS72-RS-120 surge protector; data sheet
•Delta LA-302 lightning arrestor; website
•Midnite solar surge protection device MNSPD-300 or
MNSPD-300FM (with flush mount box); website
•Citel DS73-RS-G surge protector; data sheet
•Delta LA-303 lightning arrestor; website
NOTE: Protection against lightning and resulting voltage surge must be in accordance with
local standards.

microinverter on the underside of the ACM is at least 1.9 cm (0.75 in.) away from the roof or
installation surface.
B. Do not place the ACMs in such a way that places pressure on the microinverter. Minimum
distance from the top edge of the module to the rail should be about 30 cm (12 in.).
C. Make sure that the minimum gap between modules is 10 mm (0.4 in.) or greater.
D. Check that rails and clamps are clear of the microinverter by at least 3.8 cm (1.5 in.). Do not
obstruct module drain holes.
Step 7: Connect the Microinverters as you Install the ACMs
A. Check again that the ACMs are not placing pressure on the microinverter. Minimum distance from
the top edge of the module to the rail should be about 30 cm (12 in.).
B. As you install each ACM, connect the Q Cable to the microinverter. Listen for a click as the
connectors engage.
C. Cover any unused connectors on the AC cable with Enphase Sealing Caps. Listen for a click as
the sealing caps engage.
WARNING: Risk of electric shock. Risk of fire. Install sealing caps on all unused AC
connectors as these connectors become live when the system is energized. Sealing caps
are required for protection against moisture ingress.

Step 8: Manage the Cabling
A. Use cable clips to attach the cable to the module frame. Leave no more than 1.8 m (six feet)
between cable clips.
Cable clip
B. Dress any excess cabling in loops so that it does not contact the roof. Do not form loops smaller
than 12 cm (4¾ “) in diameter.
WARNING: Tripping Hazard. Loose cables can become a tripping hazard. Dress the
Enphase Q Cable to minimize this potential.
NOTE: Some modules do not include framing on their shortest side. Cable clips cannot
attach to the frameless side for cable management. Plan to use the longer, framed side
for cable management when this is the case.
