M215 Microinverter Installation Planning
The Enphase M215 Microinverter
The M215 Microinverter is Enphase's most powerful
and efficient model yet. This grid -tied microinverter
is compatible with most 60-cell PV modules (up to
260W) and Installs quickly and easily. It worKS with
both three-phase 208 Vac or single-phase 240 Vac
services in North America; voltage is determined by
cable type.
For detailed installation information, refer to the
M215 Znstatiation and Operations Manual and
the M215 Quick Znstall Guide at
http://www.enphase.com/support/downlQads.
Microinverter Compatibility
e enp
A
The M215 should be paired only with a 60-cell PV module. Refer to the Enphase website
(http://www.enphase.com/-support/downloads) for a list of electrically -compatible PV modules and
approved PV module racking systems.
To ensure mechanical compatibility, be sure to order the correct Module Connector Type for both
microinverter and PV module from your distributor.

*Note: Tyco connectors on PV modules can vary in polarity, and either the male or female connector
may be positive. Only the MALE positive will mate with Enphase Microinverters with S23 connectors.
Be sure to order the correct connector type for both microinverter and PV module from your
distributor.
As a rule, the electrical ly-positive output of the PV module always connects to the positive input of the
microinverter. However, PV modules come with a variety of labels. For more information, refer to
Mating Microinverters with PV Modules for Correct Polarity under the Enphase downloads at
http://www.enphase.com/support/downloads.
Branch Circuit Capacity
Do not exceed the maximum number of microinverters in an AC branch circuit as listed in the
following table. You must protect each microinverter AC branch circuit with a 20A maximum breaker.

Enphase Engage Cabling System
The M215 incorporates DC connectors and an AC connector. There is no integral AC cable on the
M215. The Enphase Cabling System accomplishes the AC connection.
The Cabling System is a continuous length of 12 AWG, outdoor rated cable, with integrated connectors
for microinverters. These connectors are Preinstalled along the entire cable and spaced to
accommodate both portrait and landscape PV
rnnrllll� ; f. 44
en a ons.
The cable is installed by simply rolling out the
desired length of cable and cutting it to size. One
end is wired directly into the junction box at the
head of the branch circuit, eliminating the need for a
separate AC interconnect cable. The other end is
sealed from the environment using an Enphase
Branch Terminator. The M215 AC cable connectors
are then plugged into the regularly -spaced
connectors as shown.
The Enphase Cabling System is available in two
connector spacing options and two voltage types.
Depending upon installer needs, the cabling is also available in a variety of lengths.
Connector Spacing Options
The gap between connectors on the cable can be either 1.025 meters (40") or 1.7 meters (67"). The
1.025 meter spacing is best suited for connecting PV modules installed in portrait mode, while the 1.7
meter gap is best suited to PV modules installed in landscape mode.

firVoltage Types and Conductor Count
The voltage types are either 240VAC split phase or 208VAC three phase. All cable connectors bear
labels Indicating their cable voltage designation. Typically used for residential applications,
240VAC includes four conductors. This cabling should also be used for split phase 208VAC
applications. Three-phase 208VAC cabling includes five conductors, and Is used for most commercial
installations. Because Enphase microinverters output onto two phases, three phase cabling balances
the phases by rotating conductor use from one microinverter to the next as shown in the following
diagram. In the diagram, the three phases are labeled A, B, and C.
Racking Compatibility
Engage Cabling is compatible with a variety of racking systems. For a list of approved PV module
racking types, refer to the Racking Compatibility document at
(http://www.enphase,com/suppor-t/downloads).
Cabling Length Options
Engage Cabling Is available in shorter lengths with 30-40 connectors, depending upon voltage type.
Longer lengths can be ordered and cut to suit per order. Ordering options Include:

Planning for Cable Lengths and Type
The Cabling System is flexible enough to adapt to almost any solar design. To determine the length
and cable type that you need, take into account the following considerations:
• The number of Enphase Microinverters to be installed on the AC branch. Be certain to
allocate the correct number of connectors, including extra connectors for gaps and turns.
• Additional length required to reach from the AC branch circuit junction box to the
first microinverter. If greater than half a connector cable interval is needed, it may be
necessary to include one (or more) unused connectors in order to span this distance. Unused
connectors must be covered with Enphase watertight sealing caps.
• Additional length required to reach from one row of PV modules to the next. If the PV
modules are laid out in multiple rows, the distance from one row to the next often requires
additional cabling length.
• Bend radius. When planning cabling turns or loops, You must account for a minimum bend
radius of 6.7 cm (2.625").
• Multiple sub -arrays. Often, the AC branch circuit may be composed of several smaller sub -
arrays across more than one roof plane. In this case, the cable is cut to service each smaller
array, and the sub -arrays are connected together using appropriately rated runs of conduit.
The transition from cable to conduit is accomplished using an outdoor rated junction box, as
required by the NEC and local code. Unused connectors must be covered with Enphase
watertight sealing caps.
Mixture of PV modules in both portrait and landscape installation. Often, PV
installations use modules installed in mixed orientation (both portrait and landscape mode). In
this case there are three choices for cabling: .
1. Cabling with 1,025 meter spacing between connectors results in cleanest Install for the
modules in portrait mode. For modules placed in landscape mode, plan for an unused
connector between each PV module to achieve the required additional distance. Unused
connectors must be covered with Enphase watertight sealing caps.
2. Cabling with 1.7 meter spacing between connectors results in cleanest install for the
modules in landscape mode, but requires that any additional cable length between PV
modules in portrait mode be coiled and dressed so that cabling does not contact the roof.
Again, unused connectors must be covered with Enphase watertight sealing caps,
3. Another solution when modules are installed in mixed orientation is to transition between
1.025 and 1.7 meter spacing cable options using an outdoor rated junction box, This
junction box can be installed to the PV module railing.

SolarMount Unirac Code -Compliant Installation Manual "18UNIRAC
Part 1. Procedure to Determine the Design Wind Load
[1.1.] Using the Simplified Method - ASCE 7-05
The procedure to determine Design Wind Load is specified
by the American Society of Civil Engineers and referenced in
the International Building Code 2009. For purposes of this
document, the values, equations and procedures used in this
document reference ASCE 7-05, Minimum Design Loads for
Buildings and Other Structures. Please refer to ASCE 7-05 if
you have any questions about the definitions orprocedures
presented in this manual. Unirac uses Method 1, the
Simplified Method, for calculating the Design Wind Load for
pressures on components and cladding in this document.
The method described in this document is valid for flush, no
tilt, SolarMount Series applications on either roofs or walls.
Flush is defined as panels parallel to the surface (or with no
more than 3" difference between ends of assembly) with no
more than 10" space between the roof surface, and the bottom
of the PV panels.
This method is not approved for open structure calcula tions.
Applications of theseprocedures is subject to thefollowmg
ASCE 7-05 limitations:
1. The building height must be less than 60 feet, h < 60. See
note for determining h in the next section. For installations
on structures greater than 60 feet, contact your local Unirac
Distributor.
2. The building must be enclosed, not an open or partially
enclosed structure, for example a carport.
3. The building is regular shaped with no unusual geometrical
irregularity in spatial form, for example a geodesic dome.
4. The building is not in an extreme geographic location such
as a narrow canyon or steep cliff.
5. The building has a flat or gable roof with a pitch less than 45
degrees or a hip roof with a pitch less than 27 degrees.
6. If your installation does not conform to these requirements
please contact your local Unirac distributor or a local
professional engineer.
If your installation is outside the United States or does not
meet all of these limitations, consult a local professional
engineer or your local building authority. Consult ASCE 7-05
for more clarification on the use of Method 1. Lower design
wind loads may be obtained by applying Method II from ASCE
7-05. Consult with a licensed engineer if you want to use
Method 11 procedures.
The equation for determining the Design Wind Load for
components and cladding is:
Pnet (PSf) = A1CztrPnet30
p,,,t (psf) = Design Wind Load
A = adjustmentfactorfor building height and exposure category
K,t = Topographic Factor at mean roof height, h (ft)
I = Importance Factor
Pn,t3o (PSO = net design windpressurefor Exposure B, at height
30feet, I = 1.0
You will also need to know the following information:
Basic Wind Speed = V (mph), the largest 3 secondgust ofwind in
the last SO years.
h (ft) = total roof heightforflat roof buildings or mean roof height
forpitched roof buildings
Roof Pitch (degrees)
This manual will help you determine:
EJ�ctive Wind Area (sf) = minimum total continuous area of
modules being installed (Step 2)
R o of Zo ne = th e a rea of th e ro ofyo u are ins ta Iling the p v syste m
according to Step 3.
RoofZone Dimension = a (ft) (Step 3)
Exposure Category (Step 6)
[1.2.1 Procedure to Calculate Total Design Wind
The procedure for determining the Design Wind Load can be
broken into steps that include looking up several values in
different tables. Table 5 has been provided as a worksheet for
the following 9 steps (page 8)
Step 1: Determine Basic Wind Speed, V (mph)
Determine the Basic Wind Speed, V (mph) by consulting your
local building department or locating your installation on the
maps in Figure 1, page 4.
Step 2: Determining Effective Wind Area
Determine the smallest area of continuous modules you will
be installing. This is the smallest area tributary (contributing
load) to a support or to a simple -span of rail. That area is the
Effective Wind Area, the total area of the fewest number of
modules on a run of rails. If the smallest area of continuous
modules exceeds 100 sq ft, use 100 sq ft (See Table 2). If less,
round down to values available in Table 2.

Step 5: Determine the Topographic Factor, K%t
For the purposes of this code compliance document, the
Topographic Factor, Kzt, is taken as equal to one (1), meaning,
the installation is surrounded by level ground (less than 10%
slope). If the installation is not surrounded by level ground,
please consult ASCE 7-05, Section 6.5.7 and the local building
authority to determine the Topographic Factor.
Step 6: Determine Exposure Category (B, C,� D)
Determine the Exposure Category by using the following
definitions for Surface Roughness Categories.
The ASCE/SEI 7-05 defines wind surface roughness
categories as follows:
SURFACE RoUGHNESS B: is urban and suburban areas,
wooded areas, or other terrain with numerous closely
spaced obstructions having the size of single family
dwellings.
SURFACE RoUGHNESS c: has open terrain with scat-
tered obstructions having heights generally less than
30 feet. This category includes flat open country,
grasslands, and all water surfaces in hurricane prone
regions.
SURFACE RoUGHNESS D: has flat, unobstructed areas
and water surfaces outside hurricane prone regions.
This category includes smooth mud flats, salt flats, and
unbroken ice.
Also see ASCE 7-05 pages 287-291 for further explanation and
explanatory photographs, and confirm your selection with the
local building authority.

Using the Exposure Category (Step 6) and the roof height,
h (ft), look up the adjustmentfactorfor height and exposure in
Table 4.
Step 8: Determine the Importance Factor, I
Determine if the installation is in a hurricane prone region.
Look up the Importance Factor, I, Table 6, page 9, using the
occupancy category description and the hurricane prone
region status.
Step 9: Calculate the Design Wind Load, Pnet (Psf)
Multiply the Net Design Wind Pressure, Pnet3o (psf) (Step 4) by
the adjustmentfactorfor height and exposure, A (Step 7),the
Topographic Factor, K-a (Step 5), and the Importance Factor, I
(Step 8) using the following equation, or Table 5 Worksheet.
Pnet (Psf) = AKztIpnet3O
pnet (psf) = Design Wind Load (10 psf m inim um)
A = adjustmentfactorfor height and exposure category (Step 7)

Part H. Procedure to Select Rail Span and Rail Type
[2. 1.] Using Standard Beam Calculations, Structural Engineering Methodology
The procedure to determine the Unirac SolarMount series
rail type and rail span uses standard beam calculations and
structural engineering methodology. The beam calculations
are based on a simply supported beam conservatively, ignoring
the reductions allowed for supports of continuous beams over
multiple supports. Please refer to Part I for more information
on beam calculations, equations and assumptions. if beams
are installed perpendicular to the eaves on a roof steeper than
a 4/12 pitch in an area with a gr6und snow load greater than
30psf, then additional analysis is required for side loading on
the roof attachment and beam.
in using this document, obtaining correct results is
dependent upon the following:
1. Obtain the Snow Load for your area from your local building
official.
2. obtain the Design Wind Load, P,et- See Part I (Procedure
to Determine the Design Wind Load) for more information on
calculating the Design Wind Load.
3. Please Note: The terms rail span and footing spacing
are interchangeable in this document. See Figure 3 for
illustrations.
4. To use Table 8 and Table 9 the Dead Load for your specific
installation must be less than 5 psf, including modules and
Unirac racking systems. if the Dead Load is greater than 5
psf, see your Unirac distributor, a local structural engineer or
contact Unirac.
The following procedure will guide you in selecting a Unirac
rail for a flush mount installation. It will also help determine
the design loading imposed by the Unirac PV Mounting
Assembly that the building structure must be capable of
supporting.
Step 1: Determine the Total Design Load
Figure 3. 1
spacing ar
P-9.
10
The Total Design Load, P (psf) is determined using ASCE 7-05
2.4.1 (ASD Method equations 3,5,6 and 7) by adding the Snow
Loadl, S (psf), Design Wind Load, Pna (PSO from Part I, Step 9
and the Dead Load (psf). Both Uplift and Downforce Wind
Loads calculated in Step 9 of Part I must be investigated. Use
Table 7 to calculate the Total Design Load for the load cases.
Use the maximum absolute value of the three downforce cases
and the uplift case for sizing the rail. Use the uplift case only
for sizing lag bolts pull out capacities (Part H, Step 6). Use the
following equations or Table 7.
P (Psf) = 1.OD + 1.01 (downforce case 1)
P (psf) = LOD + 1.0pna (downforce case 2)
P (psf) = LOD + 0.75SI + a7Sp,,,t (downforce case 3)
P (psf) = 0.6D + 1-OPnet (Uplift)
D Dead Load (psf)
S Snow Load (psf)
p,,,t = Design Wind Load (psf) (Positivefor downforce, negative
for uplift)
The maximum Dead Load, D (Psf), is S vsf based on market
research and internal data.
1 Snow Load Reduction - 7he snow load can be reduced according
to Chapter 7 ofASCE 7-OS. 7he reduction is afunction of the roof
slope, Exposure Factor, Importance Factor and 7hermal Factor.
Please refer to Chapter 7 of ASCE 7-OSfor more information.

Step 2: Determine the Distributed Load on the rail,
W (P V)
Determine the Distributed Load, w (p4f), by multiplying the
module length, B (ft), by the Total Design Load, P (psf) and
dividing by two. Use the maximum absolute value of the three
downforce cases and the Uplift Case. We assume each module
is supported by two rafls.
w = PB12
w =Distributed Load (pounds per linearfoot, p4f)
B = Module Length Perpendicular to Rails (ft)
P = Total Design Pressure (pounds per squarefibot, psf)
Table 8. L-Foot SolarMount Series Rail Span
SM - SolarMount HD - SolarMount Heavy Duty
Step 3: Determine Rail Span/L-Foot Spacing
Using the distributed load, w, from Part 11, Step 2, look up the
allowable spans, L, for each Unirac rail type, SolarMount (SM)
and SolarMount Heavy Duty (HD).
The L-Foot SolarMount Series Rail Span Table uses a single
L-foot connection to the roof, wall or stand-off. Please refer to
the Part III for more installation information.

Step 4: Select Rail Type
Selecting a span and rail type affects the price of your
installation. Longer spans produce fewer wall or roof
penetrations. However, longer spans create higher point load
forces on the building structure. A point load force is the
amount of force transferred to the building structure at each
connection.
It is the installer's responsibilfty to verify that the building
structure is strong enough to support the point load
forces.
Table 10. Downforce Point Load Calculation
Step 5: Determine the Do-Amforce Point Load, R (Ibs),
at each connection based on rail span
When designing the Unirac Flush Mount Installation, you
must consider the downforce Point Load, R (lbs) on the roof
structure.
The Downforce, Point Load, R (Ibs), is determined by
multiplying the Total Design Load, P (psf) (Step 1) by the Rail
Span, L (ft) (Step 3) and the Module Length Perpendicular to
the Rails, B (ft) divided by two.
R (Ibs) = PLB12
R = Point Load (Ibs)
P = Total Design Load (psf)
L = Rail Span (ft)
B = Module Length Perpendicular to Rails (ft)
it is the installer's responsibility to verify that the building
structure is strong enough to support the maximum point
loads calculated according to Step 5.

(3.2. 1] Planning your SolarMount installations
The installation can be laid out with rails parallel to the rafters
or perpendicular to the rafters. Note that SolarMount rails
make excellent straight edges for doing layouts.
Center the installation area over the structural members as
much as possible.
Leave enough room to safely move around the array during
installation. Some building codes require minimum clearances
around such installations, and the user should be directed to
also check'The Code'.
P.S.
16
The width of the installation area equals the length of one
module.
The length of the installation area is equal to:
• the total width of the modules,
• plus 1 inch for each space between modules (for mid -
clamp),
• plus 3 inches (11/2 inches for each pair of end clamps).

SolarMount Unirac Code- Compliant Installation Manual .90-so- U N I RAC
[3.2.41 Installing SolarMount rails
Keep rail slots free of roofing grit or other debris. Foreign matter will
cause bolts to bind as they slide in the slots.
installing Splices: If your installation uses SolarMount splice bar's, attach
the rails together (Fig. 13) before mounting the rails to the footings. Use
splice bars only with flush installations or those that use low -profile tilt
legs.
Although structural, the joint is not as strong as the rail itself. A rail should
always be supported by more than one footing on both sides of the
splice. (Reference installation manual 908, Splices/Expansion Joints.)
Mounting Rails on Footings: Rails may be attached to either of two
mounting holes in the L-feet (Fig. 14). Mount in the lower hole for a low
profile, more aesthetically pleasing installation. Mount in the upper hole
for a higher profile, which will maximize airflow under the modules. This
will cool them more and may enhance performance in hotter climates.
Slide the %-inch mounting bolts into the footing bolt slots. Loosely attach
the rails to the footings with the flange nuts.
Ensure that the rails are oriented to the footings as shown in Figure 8, 9,
11, or 12, whichever is appropriate.
Aligning the Rail End: Align one pair of rail ends to the edge of the
installation area (Fig. 15 or Fig. 16).
The opposite pair of rail ends will overhang the side of the installation
area. Do not trim them off until the installation is complete.

if the rails are perpendicular to the rafters (Fig. 15), either end of the rails Figure 14. Foot -to -rail splice attachment
can be aligned, but the first module must be installed at the aligned end.
If the rails are parallel to the rafters (Fig. 16), the aligned end of the rails
must face the lower edge of the roof. Securely tighten all hardware after
alignment is complete (20 ft lbs).
Mount modules to the rails as soon as possible. Large temperature
changes may bow the rails within afew hours if module placement is
delayed.

[3.2.5] Installing the modules
Pre -wiring Modules: if modules are the Plug and Play type,
no pre -wiring is required, and you can proceed directly to
"Installing the First Module" below.
if modules have standard i-boxes, each module should be
pre -wired with one end of the intermodule cable for ease of
installation. For safety reasons, module pre -wiring should not be
performed on the roof.
Leave covers off J-boxes. They will be installed when the
modules are installed on the rails.
Installing the First Module: in high -profile installations, the
best practice would be to install a safety bolt (1/4"-20 x 1/2") and
flange nut (both installer provided) fastened to the module bolt
slot at the aligned (lower) end of each rail. It will prevent the
lower end clamps and clamping bolts from sliding out of the rail
slot during installation.
If there is a return cable to the inverter, connect it to the first
module. Close the J-box cover. Secure the first module with
T-bolts and end clamps at the aligned end of each rail. Allow
half an inch between the rail ends and the end damps (Fig.18).
Finger tighten flange nuts, center and align the module as
needed, and securely tighten the flange nuts (10 ft lbs).
Installing the Other Modules: Lay the second module face
down (glass to glass) on the first module. Connect intermodule
cable to the second module and close the J-box cover. Turn the
second module face up (Fig. 17). With T-bolts, mid -clamps and
flange nuts, secure the adjacent sides of the first and second
modules. Align the second module and securely tighten the
flange nuts (Fig. 19).
For a neat installation, fasten wire management devices to rails
with self -drilling screws.
Repeat the procedure until all modules are installed. Attach the
outside edge of the last module to the rail with end clamps.
Trim off any excess rail, being careful not to cut into the roof.
Allow half an inch between the end clamp and the end of the rail
(Fig. 18).

[3.3. 11 Planning the installation area
Decide on an arrangement for clips, rails, and L-feet (Fig. 22).
Use Arrangement A if the full width of the rails contacts the
module. Otherwise use Arrangement B.
Caution: Ifyou choose Arrangement B, either
(1) use the upper mounting holes of the L-Jeet or
(2) be certain that the L-Jeet and clip positions don't
conflict.
If rails must be parallel to the rafters, it is unlikely that they
can be spaced to match rafters. In that case, add structural
supports — either sleepers over the roof or mounting blocks
beneath it. These -additional members must meet code; if in
doubt, consult a professional engineer.
Never secure the footings to the roof decking alone. Such an
arrangement will not meet code and leaves the installation
and the roof itself vulnerable to severe damage from wind.
Leave enough room to safely move around the array during
installation. The width of a rail -module assembly equals the
length of one module. Note that L-feet may extend beyond
the width of the assembly by as much as 2 inches on each
side. The length of the assembly equals the total width of the
modules.

[3.3.21 Laying out the instaRing L-feet
L-feet are used for installation through
existing low profile roofing material, such
as asphalt shingles or sheet metal. They
are also used for most ground mount
installations. To ensure that the L-feet will
be easily accessible during flush installation:
• Use the PV module mounting holes
nearest the ends of the modules.
• Situate the rails so that footing bolt
slots face outward.
The single slotted square side of the L-foot
must always lie against the roof with the
double -slotted side perpendicular to the
roof.
Foot spacing (along the same rail) and rail
overhang depend on design wind loads.
InstaR half the L-feet:
• If rails are perpendicular to rafters
(Fig. 23), install the feet closest to
the lower edge of the roof.
• If rails are parallel to rafters
(Fig. 24), install the feet for one of
the rails, but not both.
For the L-feet being installed now, drill pilot
holes through the roofing into the center of
the rafter at each lag screw hole location.
Squirt sealant into the hole and onto the
shafts of the lag screws. Seal the underside
of the L-feet with a sealant. Securely fasten
the L-feet to the building structure with the
lag screws. Ensure that the Lfeet face as
shown in Figure 23 or Figure 24.
Hold the rest of the L-feet and fasteners
aside until the panels are ready for the
installation.

[3.3.31 Attaching modules to the rails
Lay the modules for a given panel face down on a surface
that will not damage the module glass. Align the edges of the
modules and snug them together (Fig. 21, page 22).
Trim the rails to the total width of the modules to be mounted.
Place a rail adjacent to the outer mounting holes. Orient
the footing bolt slot outward. Place a clip slot adjacent to
the mounting holes, following the arrangement you selected
earlier.
Assemble the dips, mounting bolts, and flange nuts. Torque
the flange nuts to 10 foot-pounds.
[3.3.4] Installing the module -rail assembly
Bring the module -rail assembly to the installation site. Keep
rail slots free of debris that might cause bolts to bind in the
slots.
Consider the weight of a fully assembled panel. Unirac recom-
mends safety lines whenever lifting one to a roof.
Align the panel with the previously installed L-feet. Slide 3/8
inch L-foot mounting bolts onto the rail and align them with
the L-feet mounting holes. Attach the panel to the L-feet and
finger tighten the flange nuts.
Rails may be attached to either of two mounting holes in the
footings (Fig. 25).
• Mount in the lower hole for a low, more aethetically
pleasing installation.
• Or mount in the upper hole to maximize a cooling
airflow under the modules. This may enhance perfor-
mance in hotter climates.
Adjust the position of the panel as needed to fit the installa-
tion area. Slide the remaining L-feet bolts onto the other rail,
attach L-feet, and finger tighten with flange nuts. Align L-feet
with mounting holes previously drilled into the roof. Install
lag bolts into remaining L-feet as described in "Laying out and
installing L-feet" above.
Torque all footing flange nuts to 30 foot-pounds. Verify that all
lag bolts are securely fastened.
