Safety and Installation Instructions for AC Modules
IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS
1.0
Introduction
This document provides safety and installation instructions for the
Maxeon AC photovoltaic (PV) modules described herein, all of which
bear both TUV and EnTest logos on the product label in respect to DC
and AC (Microinverter) standards:
1.1 Definition of Terms
AC Module: Maxeon 5 AC module
DC Module: A typical photovoltaic solar module without microinverter unit
attached.
Enphase Microinverter: Smart grid ready IQ 7A microinverter converts the DC
output of the PV module into grid-compliant AC power.
Enphase AC cable: also called Q Cable, it is an AC cable with a length varying from
1.3m to 2.3m depending to AC Module orientation (Portrait or Landscape), with
3.3 mm2 cross section, double insulated, outdoor rated with integrated
connectors for microinverters. AC Module plug directly into the cable connectors.
Enphase Enlighten: Web-based monitoring and management software. Installers
can use Enlighten Manager to view detailed performance data, manage multiple
PV systems, etc.
DC Connector: Maxeon Solar Technologies recommends using the same brand
connector in a given PV system. Approved compatible connectors: Tyco
Electronics PV4S
1.2 Disclaimer of Liability
The installation techniques, handling and use of this product are beyond company
control. Therefore, Maxeon Solar Technologies does not assume responsibility for
loss, damage, or expense resulting from improper installation, handling, or use.
1.3 Certified Body Certification Information
This product intents to meet or exceed the requirements set forth by IEC 62109-
3 for Maxeon AC modules (not yet released). The IEC 62109-3 Standard covers
flat-plate PV modules intended for installation on buildings; or those intended to
be freestanding. The TUV certification does not include integration into a building
surface because additional requirements may apply. This product is not intended
for use where artificially concentrated sunlight is applied to the module. This
manual shall be used in combination with industry recognized best practices and
AC modules should be installed by certified professionals only.
1.4 Limited Warranty
AC Module limited warranties are described in the Maxeon Solar Technologies
warranty certificates obtainable at
(Refer to the
limited warranty document).

Safety Precautions
Before installing this device, read all safety instructions in this document.
•
Disconnect the AC source from all AC Modules and/or cover all modules in
the PV array with an opaque cloth or material before making or breaking
electrical connections
•
Do not connect or disconnect modules when current from the modules in the
string or an external source is present
•
Use only the AC locking connectors in order to defend against untrained
personnel disconnecting the modules after they have been installed.
•
All installations must be performed in compliance with the applicable local
codes.
•
Installation should be performed only by qualified and suitably licensed
personnel
•
Remove all metallic jewelry prior to installing this product to reduce the
chance of accidental exposure to live circuits.
•
Use only insulated tools to reduce your risk of electric shock.
•
Do not stand on, drop, scratch, or allow objects to fall on AC Modules.
•
Broken glass, J-boxes, broken connectors, and/or damaged backsheets are
electrical hazards as well as laceration hazards. If a module is cracked after
installation, a qualified person should remove the module from the array and
contact the supplier for disposal instructions.
•
Do not install or handle modules when they are wet or during periods of high
wind.
•
Unconnected connectors must always be protected from pollution (e.g. dust,
humidity, foreign particles, etc.), prior to installation. Do not leave
unconnected (unprotected) connectors exposed to the environment. A clean
installation environment is essential in order to avoid performance
degradation.
•
Do not block drain holes or allow water to pool in or near AC Module frames
•
Contact your module supplier if maintenance is necessary.

Electrical Characteristics
Electrical characteristics and grid interaction data are shown in Table 3 and AC
Module datasheet. It is the installer’s responsibility to set the grid profile and to
check Enphase pre-configured country grid detail and this can be done with
internet access and by connecting into the Enphase Enlighten system.
If an installation involves a Maxeon AC module which does not appear on this list,
please consult the product label on the back of the module or visit
for the product datasheet.
As a reminder for DC modules: a photovoltaic module may produce more current
and/or voltage than reported at STC. Sunny, cool weather and reflection from
snow or water can increase current and power output. Therefore, the values of
Isc and Voc marked on the module should be multiplied by a factor of 1.25 when
determining component voltage ratings, conductor ampacities, fuse sizes, and
size of controls connected to PV output. An additional 1.25 multiplier may be
required by certain local codes for sizing fuses and conductors. SunPower
recommends the use of open- circuit voltage temperature coefficients listed on
the datasheets when determining Maximum System Voltage.
3.1 Fire Rating
The AC Module maintains the same Class C fire rating associated with DC
modules.
Important!
Please read these instructions in their entirety before
installing, wiring, or using this product in any way. Failure to comply
with these instructions will invalidate the Maxeon Solar
Technologies Limited Warranty for PV Modules and/or Enphase
Energy Limited Warranty for microinverters.
Danger!
AC Modules generate internal direct current (DC) and output
alternating current (AC); and are a source of voltage when under load and
when exposed to light.
Electrical currents can arc across gaps and may
cause injury or death if improper connection or disconnection is made; or if
contact is made with module leads that are frayed or torn.
