With the M250, the DC circuit is isolated and insulated from ground, so no Ground Electrode Conductor.(GEC) is required for the microinverter. This further simplifies installation, enhances safety, and saves on labor and materials costs. The Enphase M250 integrates seamlessly with'the Engage Cable, the Envoy® Communications Gateway", and Enlighten®, Enphase's monitoring and analysis software. PRODUCTIVE SIMPLE RELIABLE Optimized for higher -power - No GEC needed for microinverter - 4th -generation product modules - No DC design or string calculation - More than 1 million hours of testing - Maximizes energy production required and millions of units shipped - Minimizes impact of shading, - Easy installation with Engage —Industry-leading warranty, up'to 25 dust, and debris Cable years r [e] enphase E N E R G Y C us Enphase® M250 Microinverter // DATA INPUT DATA (DC) M250-60-2LL-S22, M250-60-2LL-S25 Recommended input power'(STC)'` ;, ws ` 210 = 310 W Maximum input DC voltage 48 V Peak power tracking voltage: L= 't�;� :°� .

In order to ground the SOLARMOUNT racking system through the Enphase microinverter and Engage cable assembly, there must be a minimum of three �., "gam ~� PV modules connected to the same trunk cable within a continuous row. �- Continuous row is defined as a grouping of modules installed and bonded per the requirements of this installation guide sharing the same two rails. The microinverters are bonded to the SOLARMOUNT rail via the mounting hardware. Complete equipment roundin9is achieved through the Enphase Engage cabling with integrated grounding (IG). No additional EGC grounding cables are required, as all fault current is carried to ground through the Engage cable.

SOLARMOUNT has achieved Class A, B & C system level performance for steep sloped roofs when used in conjunction with type 1, type 2, type 3 and type 10 module constructions. Class A, B & C system level fire performance is inherent in the SOLARMOUNT design, and no additional mitigation measures are required.The fire classification rating is onlyvalid on roof pitches greater than 2:12 (slopes,: 2 inches per foot, or 9.5 degrees).

QuickTip: Pre-driLLthe pilot holethrough the flat flashing Lag bolt Location for easier installation. 2 PIECE ALUMINUM STANDOFF WITH FLASHING & L -FOOT: • If necessary cut an opening in the roofing material over a rafter to accommodate the flashing riser. • Install the standoff, ensuring that both Lag bolts are screwed into the rafter. • Insert the flashing under the shingle above and over the shaft of the standoff, (No-CalkTM' collar does not require sealing of the flashing and standoff shaft) • Add L -Foot to top with bolt that secures the EPDM washer to the top of the standoff. See Standoffs & Flashings Installation Manual 907.2 for Additional Details. FLAT FLASHING INSTALLATION: Insert the Flat Flashing so the top part is under the next row of shingles and the hole Lines up with the pilot hole. INSTALL LAG BOLTS & L -FOOT: Insert the Lag bolt through the L -Foot in the order shown in the illustration. Verify proper orientation before tightening Lag bolts. See Unirac Flat Flashing Manual for Additional Details. TOP MOUNT TILE HOOK & L -FOOT: • Remove or slide up the roof tile, position the roof hook above the roof rafter • Place Tile Hook in the middle of the underlying interlocking tile's valley. Drill 3/16 inch pilot holes through the underlayment into the center of the rafters. Securely fasten each the hook to the rafters with two 5/16" x 31/2" lag screws. Slide down or re-insert the tile. • Attach L Foot to tile roof hook. See Tile Hook Universal Mount Installation Manual for Additional Information. MEN SM SOLAR SPLICE & THERMAL BREAK � ■■ MOUNT INSTALLATION GUIDE ;PAGE J it .--•a.� � - � � . � f �- .moo .ti- •> ylti k SPLICE INSTALLATION (IF REQUIRED PER SYSTEM DESIGN) If your installation uses SOLARMOUNT splice bars,attach the rails together before mounting to the L -feet / footings. Use splice bars only with flush installations or those that use tow -profile tilt legs. A rail should always be supported by more than one footing on both sides of the splice. There should be a gap between rails, up to 3/16" at the splice connections. T -bolts should not be placed less than a distance of 1" from the end of the rail regardless of a splice. TORQUE VALUE (See Note on PG. A) Hex head socket size 5/16"- Do not exceed 10 ft -lbs. Do not use Anti -Seize. Max length of spliced rail is 40 ft. An expansion joint is required > 40 ft. EXPANSION JOINT USED AS THERMAL BREAK Expansion joints prevent buckling of rails due to thermal expansion. Splice bars may be used for thermal expansion joints.- To create a thermal expansion joint, slide the splice bar into the footing slots of both rail lengths. Leave approxi- mately '/i" between the rail segments. Secure the splice bar with two screws on one side only. Footings (such as L -feet or standoffs) should be secured normally on both sides of the splice. No PV module or mounting hardware component should straddle the expansion joint. Modules must clearly end before the joint with mounting hardware (top mount Endclamps) terminating on that rail.T-bolts should not be placed less than a distance of 1" from the end of the rail regard- less of a splice. The next set of modules would then start after the splice with mounting hardware beginning on the next rail. A thermal break is required every 40 feet of continuously connected rail. For additional concerns on thermal breaks in your specific project, please consult a licensed structural engineer. Runs of rail less than 40 feet in length, with more than two pairs spliced together, are an acceptable installation for the SOLARMOUNT systems. Bonding connection for splice used as a thermal break. Option shown uses two Ilsco lugs (Model No. GBL-4DBT P/N GBL-4DBT - see product data sheet for more details) and solid copper wire. 00:p�SOLAR ATTACH RAIL TO L -FEET s❑ °o°o° � J 'MOUNT INSTALLATION GUIDE � PAGE .......----- ...........:..---------------------------------- :---------------------------------------------------------- ---------------------- � "t.,r�� w.J.°!".,,y.. ate-•= "� O� ,k•, - ,, :. bolt.:"*' scar ,;,�,•�,,. +:r yj•:���.;wi��'.. id's%` w^� 3 Z "rte `tr Al ry -_ -j 0. t top PLACE T BOLT INTO RAIL: Insert 3/8" SECURE T BOLT: Apply Anti -Seize to CONNECT RAIL TO L -FOOT: Raise T -bolt into rail at L -foot Locations. bolt.

For standard system grounding a minimum 10AWG, 105°C copper grounding conductor should be used -to ground a 1000 VDC system, according to the National Electric Code (NEC). It is the installer's responsibility to check local codes, which may vary. See below for interconnection information. INTERCONNECTION INFORMATION ' There is no size limit on how many SOLARMOUNT & PV modules can be mechanically interconnected for any given configuration, provided that the installation meets the requirements of applicable building and fire codes. GROUNDING NOTES ' The -installation must be conducted in accordance with 'the National Electric Code (NEC) and the authority having jurisdiction. Please refer to these resources in your Location for required grounding Lug quantities specific to your project. The grounding/ bonding components may overhang parts of the array so care must be made when walking around the array to avoid damage. Conductor fastener torque values depend on conductor size.
