4.0 Electrical Connections and System Monitoring
Modules may be connected in series and/or parallel to achieve the desired
electrical output as long as optimum design parameters are achieved certain
conditions are met. Please use only the same type of modules in a combined
source circuit. Do not mix the modules with different nameplates without
authorization by Maxeon.
Even if allowed by local regulation, Plug and Socket connectors mated together in
a PV system must be of the same type (model, rating) from the same
manufacturer i.e. a plug connector from one manufacturer and a socket
connector from another manufacturer, or vice versa, shall not be used to make a
connection.
Maxeon recommends a conservative minimum bending radius (R) 5x cable
diameter must be maintained and must not be bent on the direct exit of the
connector or junction box. Avoid exposure of electrical connections to direct
sunlight and do not place the connector in a location where water could easily
accumulate. Installers must refer to connector manufacturer's instruction for
further installation and connection requirements.
Connectors are factory assembled with intentional gaps between the cable nut
and the body of the connector. Do not retighten module connector nuts as this
may lead to stress cracking of the connector assembly and will void the warranty.
4.1 Equipment Grounding
To reduce the possibility of electrical shock, ground the frame of the module or
array per NEC before wiring the circuit. In order to install in accordance with their
CSA Listing, Maxeon modules must be grounded using grounding hardware that
meets requirements for grounding systems in UL 61730 and UL 61215 on
anodized aluminum frames. Maxeon recommends to refer to the applicable
regional and local codes and requirements on grounding PV arrays and mounting
frames in conjunction with your racking supplier.
In addition, to avoid corrosion due to the use of dissimilar metals Maxeon
recommends stainless steel between copper and aluminum.
4.2 System Grounding
Review Table 2 below for the proper grounding techniques for the installation of
your particular Maxeon modules.
4.3 Series Connection
The modules may be wired in series to produce the desired voltage output. Do
not exceed the maximum system voltage shown in module datasheets and
product label.

For models not shown here, please contact Maxeon technical support or visit
www.sunpower.maxeon.com. Electrical parameters are measured at Standard Test
Conditions (STC). The series fuse must have an interrupting rating that is equal to or greater
than the maximum fault current that the fuse is required to interrupt, including contributions
from all connected sources of energy.
Refer to NEC Article 100, Part II as to what type of series fuse is acceptable for modules rated
at higher than 600 V dc system voltage.

4.4 Parallel Connection
The modules may be combined in parallel to produce the desired current output.
Maximum
Each series string or module may be required to be fused prior to combining with
System Voltage
UL Vmax (V) other strings if the resulting maximum fuse size allowed (number of modules
which can be connected in parallel and protected by one fuse) exceeds the fuse

rating as shown in the module datasheet and product label. Please refer to the

5.0 Module Mounting
The Maxeon Limited Warranty for PV Modules is contingent upon modules being
mounted in accordance with the requirements described in this section.
5.1 Site Considerations
Maxeon modules should only be mounted in locations that meet the following
requirements:
Operating Temperature: All Maxeon modules must only be mounted in
environments that ensure they will operate within the following temperatures:
Operating Temperature range (ambient)
Adequate ventilation should be provided behind or underneath the modules,
especially in hot environments.
Shading: Modules should be installed so that permanent shading of cells is
avoided and partial shading that may occur during certain times of the day or
year is minimized. Permanent shading is defined as shade that is cast over the
same position (of constant area) of the solar module throughout the generation
hours of the day.
Shading may induce in certain cases strong energy production reduction, even in
case of small shading and should be avoid as much as possible, especially at mid‐
day when the production is maximum.
Design Strength: Maxeon modules are designed to meet a positive (downward)
and/or negative (upward) withstanding test pressure when mounted as per the
guidelines in Section 5.2 and configurations in Appendix. Test loads are for
information purposes only; design loads should be considered for the project
design.
When mounting modules in snow prone or high wind environments, special care
should be taken to mount the modules in a manner that provides sufficient
design strength while meeting local code requirements.
Excluded Operating Environments
Certain operating environments are not recommended for Maxeon modules, and
are excluded from the Maxeon Limited Warranty.
Modules are designed for a maximum altitude of 2000 m.
No Maxeon module should be mounted at a site where it may be subject to
direct contact with salt water, or other aggressive environment.
Modules should not be installed near flammable liquids, gases, or locations with
hazardous materials; or moving vehicles of any type.
Performance Series Mounting Orientation
Commercial Performance Series (P‐Series) modules are designed to perform
better if installed in landscape orientation. In landscape orientation, P‐series
modules maintain higher power in conditions of row‐to‐row shading and/or edge
soiling.
