SW-01-6035US 08-2014 Enphase Microinverters Enphase® M250 • 1 y3 ¢ 4 t r The Enphase' M250 Microinverter delivers increased energy harvest and reduces design and installation complexity with its all-AC approach. 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.

Taggart, Vice President Products Subject: IronRidge XR100 Rail, Roof Flush Mounting System—Structural Analysis Dear Sir: We have analyzed the IronRidge XR100 Rail for the subject solar module support system and determined that, for the configurations and criteria described below, it is in compliance with the applicable sections of the following Reference Documents: Codes:ASCE/SEI 7-10 Min. Design Loads for Buildings& Other Structures - International Building Code 2012 Edition California Building Code 2013 Edition - Other: AC428, Acceptance Criteria for Modular Framing Systems Used to Support PV Modules, dated Effective November 1, 2012 by ICC-ES Aluminum Design Manual, 2010 Edition The IronRidge XR100 Rail is an extruded aluminum section with an overall depth of 2.438 in. and a net area of 0.583 sq.in. The rails are used to support solar modules, typically, on the roof of a building. See Exhibit A—attached. The rails are clamped to aluminum angle brackets that are either attached directly to the roof framing or attached to a stand that is screwed to the roof framing. The rails are mounted across the slope with a small clearance (flush mounting) to the underlying roof structure. The installed solar modules are at the same slope as the underlying roof structure. All loads are transferred to the roof framing through the angle brackets by simple bi-axial flexure of the rails. The maximum span of the rails is governed by either the mid-span flexural stresses or the deflection requirement that the rail not come into contact with the roof. The effect of seismic loads (for all design categories A-F) have been determined to be less than the effect due to wind loads in all load conditions and combinations. Therefore, the maximum allowable spans for common load cases are shown in Tables 1, 2 & 3 below for 0-6 degree slopes, Tables 4, 5, & 6 below for 7-27 degree slopes, and Tables 7, 8 & 9 below for 28-45 degree slopes.

Consulting Structural and Forensic Engineers -7 - IronRidge June 16, 2014 Mr. David F. Taggart Page 11 of 11 IronRidge XR100 Rail, Roof Flush Mounting System—Structural Analysis Notes—Tabulated values are based on the following criteria: 1. Building mean roof height=30 ft 2. Risk Category I 3. Solar module long dimension=67.5 in 4. Provide 2 in. clear between roof and rail 5. End cantilever span(max)=0.40 x maximum span from above tables 6. No rail splices in end spans 7. No rail splices in middle 1/3 of interior spans 8. Single simple span(s). Spans listed in the tables above may be multiplied by 1.08 for continuous rails of 3 or more spans. Our analysis assumes that the rails, including the connections and associated hardware, are installed in a workmanlike manner in accordance with the "IronRidge Roof Mount Installation Manual" by IronRidge and generally accepted standards of construction practice. Additional information is available at the IronRidge web site, IronRidge.com. Verification of PV Module capacity to support the loads associated with the given array shall be the responsibility of the Contractor or Owner and not IronRidge or Starling Madison Lofquist. The adequacy of the supporting roof framing is to be determined by others. Please feel free to contact me at your convenience if you have any questions.
