Title: Universal InvisiMount UL 2703 Certification 650864 Date: 11/01/2022 PN: Page 1 of 1 Form: Technical Notification Title Universal InvisiMount UL 2703 Certification, 650864 Date November 01, 2022 Author Ethan Ely, Principal Mechanical Engineer Application Universal InvisiMount® Overview SunPower recently released a new version of InvisiMount called Universal InvisiMount which pairs with SunPower U-Series modules, as well as with other modules not having a SunPower-designed module frame. As part of this project InvisiMount’s UL 2703 certification was updated to accommodate the new components and new modules. This Tech Note provides details of this certification and how to prepare for permitting. What’s Changed • Universal InvisiMount is Listed to UL 2703 by Intertek, under control number 5024883. (Classic InvisiMount remains listed to UL 2703 under UL file number E466981.) • InvisiMount is Class A fire rated with Type 1 and Type 2 module types. • All U-Series modules are included in the Intertek 2703 Listing. • All required documentation is available on the SunPower Dealer Portal: HOME page > Residential Resources > SunPower Equinox Resources. Guidance for Using Universal InvisiMount 2703 Certification Most jurisdictions require that a rooftop solar system be Listed to UL 2703, which evaluates the system’s performance, including fire resistance, electrical bonding, and mechanical capacity. Each module that will be used with the solar system’s racking hardware must be evaluated for compatibility and called out in the 2703 Listing. Modules are categorized by Types in their UL 61730 certification, with each Type number relating to a category of fire performance and module construction. The InvisiMount system has been fire tested with modules in the Type 1 and Type 2 categories, and has established fire resistance compatibility with all modules in both of these categories. The controlling documents for certification are the Certificate of Compliance for UL 61730 of the module in question, and the Authorization to Mark (ATM) for UL 2703 of Universal InvisiMount. Additionally, please reference the 2703 Intertek Module List on the SunPower Dealer Portal for a complete list of modules which are part of the Universal InvisiMount Listing. All U-Series modules are included, as well as additional modules not part of our current offering. All of these documents may be viewed on the Dealer Portal. SunPower recommends that your AHJ permit submissions include the particular module COC as well as the ATM for Universal InvisiMount. For Universal InvisiMount certification information, visit Intertek at https://ramuk.intertekconnect.com/WebClients/ITS/DLP/products.nsf/$$Search?OpenForm and search for InvisiMount. Note also that packaging for the core Universal InvisiMount components (including the end clamp, mid clamp, rail, and splice) now bear the Intertek mark and reference the UL 2703 Listing. If a local AHJ requests physical evidence of proper Listing, please provide them these packaging labels. If you have any questions please contact your RSM. Thank you for helping us change the way our world is powered. 615 S Mohawk Dr 08/24/23
