1.0 Overview and Scope
This guide describes how to install SunPower Equinox (“the system”). Do not attempt any aspect of the installation
until you have thoroughly read this entire guide. Failure to follow these instructions can result in personal injury or
equipment damage or failure, and may void the system warranty.
The system ships with the following components:
•SunPower AC modules and accessories (including extension cables)
•SunPower InvisiMount™ mounting system
•SunPower EnergyLink™ monitoring system

1.1 Safety and Warnings for Type C and Type D AC Modules
IMPORTANT SAFETY INSTRUCTIONS – SAVE THESE INSTRUCTIONS!
All personnel must adhere to the following safety procedures when working with the system, including inspection,
installation, operation, service work, repair, and testing. Failure to comply with these precautions or with specific
warnings elsewhere in this guide may violate safety standards of design, warranty, manufacture, and intended use
of the equipment. SunPower assumes no liability for failure to comply with these requirements.
Warning! The installation, adjustment, or repair of a solar system involves the risk of contact
with potentially lethal voltages and currents.
SunPower Type C and Type D AC modules meet all current requirements for rapid shutdown as defined in NEC
690.12 Rapid Shutdown of PV Systems on Buildings. As part of the UL 1741 SA / UL 1741 Listing of the SunPower AC
module product being grid support utility interactive, upon turning off the AC disconnect to de-energize the circuit
to the AC modules on the roof, each AC module output will shut off within 2.0 seconds to comply with IEEE 1547. In
this manner, all wiring leaving each AC module complies with the controlled conductor limits in 690.12.
Follow all applicable laws, including state and federal Occupational Safety and Health Administration (OSHA)
standards when working on any construction project. Always reference the National Fire Protection Agency (NFPA)
70E, Standard for Electrical Safety in the Workplace when performing electrical work.
Perform the installation in accordance with all applicable codes. In addition, reference NEC Articles 250 and 690—as
well as applicable IEC standards—for proper compliance when wiring and grounding the system. All state and
federal guidelines and regulations must be followed as well.
1.1.1 Site Safety
•These installation instructions are for use by qualified personnel only.
•System access is intended for authorized personnel only.
•Only authorized persons may shut down the system or open any system enclosure.
•To reduce the risk of fire, connect only to a dedicated circuit that has overcurrent protection not exceeding the
maximum value stated in the product’s Listing (20 A) in accordance with the NEC, ANSI/NFPA 70. Maximum
dedicated branch circuit overcurrent protection: 20 A.
•The metal components of the module can reach temperatures of approximately 176°F (80°C). Use appropriate
safety procedures when handling modules.

Document #518101 RevD 9SunPower Proprietary
1.1.2 General Warnings
•Do not attempt to service any portion of the system.
•Do not attempt installation during conditions involving rain, snow, ice, or high winds.
•Do not attempt to install or service the system if you are not a qualified, trained electrician or technician familiar
with power electronic equipment.
•Always wear rubber insulating gloves rated for the appropriate voltage level, and suitable eye and head
protection when working near live electrical equipment.
•Always have a cell phone available for calling emergency personnel.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s
authority to operate the equipment.
Note: Perform all electrical installations in accordance with any local codes and the National Electrical Code (NEC).
1.2 Installer Responsibilities
Warning!If installing the Equinox system on a metal roof, you must verify with the AHJ whether additional bonding
to the roof is required. Follow the instructions provided by the AHJ and by the roofing manufacturer.
SunPower Equinox is for residential 240 V split single-phase and 208 V three-phase wye double-pole
applications only.
Installers are solely responsible for specific aspects of the system they are installing:
•Selection and verification of design parameters, including wind and snow load and all related aspects.
•Validation of third-party roof attachment design and interoperability, including any stipulations for rail overhang
(cantilever) beyond the last roof attachment (standoff) at the end of a row. Use the SunPower Design Tool
(https://invisimountdesign.us.sunpower.com/login.html ) OR the InvisiMount Span Tables document (#524734) to
verify spans between roof attachments and maximum cantilever. (Access the Tool by logging into the Portal and
then clicking the Design Tool link.)
•Code compliance and permitting.
•Vetting system compatibility with the installation site and structures.
•Verifying the roof integrity prior to installation.
•Selecting the correct attachment and flashing type for the particular roof.
•Care of the roof during the installation.
