3. TRINAMOUNT OVERVIEW
Trinamount offers a rapid method for installing and electrically grounding solar arrays. Trinamount PV arrays are
installed without the use of rails, which greatly simplifies the process of installation. Trinamount systems consist of
Trina PV modules and Trinamount hardware. Also, Trinamount interoperates with other third party Trina Compatible
systemscomponentssuchasroofattachmenthardware,module-levelelectronics,andelectricalboxes.Trinamount
systems can be installed in either landscape or in portrait orientation. Typical residential roofs have a high aspect
ratio (length to width). As a result, typical roofs can accommodate larger arrays when installed in landscape
orientation. Landscape installations allow for more efficient use of space and can be installed faster and with greater
spans between Interlocks. An entire Trinamount array can be interconnected with the use of a single tool. Both the
Trinamount Tool and the Flat Tool provide means for installing the Interlock, the Leveling Foot, and the Ground
Lug.TheFlatToolprovidesalow-costalternativetotheTrinamountToolandalsofunctionstoenableinter-Module
removal. The Trinamount Tool can receive a T30 Torx bit for adjusting the height of the Leveling Feet.

3.2 TRINAMOUNT BASICS (THEORY OF OPERATION)
Trinamount operates in ways unlike typical mounting systems. Though the system is very simple to design and
install, it is important to understand the unique characteristics of its operation prior to installing a system. The
maindifferentiatingcharacteristicsofTrinamountarethat(1)itisrail-free,(2)itisauto-grounding,(3)itisflexible
inordertoadapttosite-specificvariables,and(4)itemploysuniqueandprecisematingtechniquesforjoining
components.
How is a Trinamount Array Supported?
Chief among Trinamount’s distinctions is that it installs without the use of mounting rails by creating structural
bonds between modules through the mating of Interlocks to the corner locations of each module’s frame. This, in
effect, causes a frame to act like a rail, and leverages the already present structural characteristics of the module
frametoallowthearraytobeself-supported.
How is a Trinamount PV Array Grounded?
The Trinamount structural connections created by the Interlocks simultaneously establish a ground bond path
between modules. The Key side of the Interlock, when rotated into the Groove of a Trina PV module, cut through
the anodized coating of the module frame to create a solid conductive bond. When an adjacent module’s groove
is dropped onto the Tongue side of the Interlock, the Tongue also cuts through the frame’s anodized coating
to create a solid conductive bond. This bond may be reversed and reset up to 50 times with no significant
degradation of the ground bond connection.
How are Trinamount Modules Wired?
Eachmodulehastwostandard90°Csunlightresistantoutputcablesthatterminatewithplug&playconnectors.
The wire type and gauge of the output cables are 600V rated PV Wire cable and are 12AWG in size. This cable is
suitable for applications where wiring is exposed to the direct sunlight. We require that all wiring and electrical
connections comply with the appropriate national electrical code.
Forfieldconnections,useaminimumof12AWGcopperwiresinsulatedforaminimumof90°CandSunlight
resistance with insulation designated as PV Wire. The minimum and maximum outer diameters of the cable are 5 to
7mm2.

• ModulePositioningisFlexible(X,Y-axisAdjustability)
WithTrinamount,XandY-axisflexibilityispossiblebecauseeachmodulecanbesetslightlyoff-axistoaccountfor
the aforementioned variability. By making minor adjustments at the module level, the installer can keep the array
alignedwithsystem-levelreferencepointssuchasalower-edgechalklineandbysightingalongseamsandedges
to keep the array looking good. The flexibility allowed in the positioning of PV modules is a result of unique system
features described below.
Interlocks, Hybrid Interlocks, and Leveling Feet all contain tongues that mate with the Grooves of Trina PV modules.
Adefiningcharacteristicofthetongue-to-grooveconnectionisthatthetonguecanseatatvariablepositionswith
respect to the groove – that is, the tongue can be fully or partially inserted into the Groove and still accomplish a
solid structural and ground bond connection. Because of this freedom, a module can be rotated slightly out of axis

How Do Trinamount Components Mate?
While Trinamount is flexible enough to adapt to variable conditions, it also employs specific and precise methods
of mating components as described below.
• KeySide/TongueSide

4.2 GATHER SITE INFORMATION
Allowable foot spacing and cantilever are based on design loads that are derived from site specific variables as
described below. The span tables are configured to factor basic wind speed, exposure category, ground snow load,
roof slope, and roof zone. However, the engineering certification letter details assumptions for other site specific
variables. If using the span tables, verify that all variables are within the assumed allowable ranges defined in the
engineering certification letter.

follow the instructions below.
Locate the Array
As a starting point for creating your array layout, determine the module’s model, length and width. Next, determine
the number of modules, row/column configuration, and module orientation. Trinamount arrays can be installed in
both landscape and portrait orientations.
Next, determine the overall array dimensions – calculating a ½” gap around each module at every vertical and
horizontal module seam. After determining the location of the array, determine what roof zones the array is in and
note any modules that are in edge or corner zones.
Configure the components
Here are the general installation rules for mounting systems:

Identify Hybrid Interlock Locations
If the location of an Interlock prevents locating a Leveling Foot on a desired rafter, simply replace the Interlock with
a Hybrid Interlock or shift the array to the east or west until all the conflicts have been eliminated.
Identify Thermal Expansion Joint Locations
After the array layout is determined, verify that thermal expansion and ground bond allowances have not been
exceeded. The array requires a thermal expansion joint at every sixth vertical Module seam. In order to accomplish a
thermal expansion joint, the Interlocks installed at the expansion joint must be only partially secured as per Section
5.13below.InterlocksinstalledinthisfashiondoNOTcarrythegroundbondsoeachportionofthearraytoeither
