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. Maxeon recommends the use of open‐
circuit voltage temperature coefficients listed on the datasheets when
determining Maximum System Voltage.

Electrical Connections
Modules may be connected in series and/or parallel to achieve the
desired electrical output as long as certain conditions are met. Please
use only the same type of modules in a combined source circuit.
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 that all
wiring be double insulated with a minimum rating of 85° C (185° F). All
wiring should use flexible copper (Cu) conductors. The minimum size
should be determined by the applicable codes. We recommend a size
2
not less than 4mm
. The insulation type should be appropriate for the
type of installation method used and must meet SCII (Safety Class II)
and IEC 61730 requirements. To minimize the risk from indirect
lightning strikes (Voltage surges), the system should be designed to
avoid loops in the wiring.
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 System & Equipment Grounding
Please refer to the applicable regional and local codes on grounding
PV arrays and mounting frames for specific requirements (e.g.
lightning protection).
Module Types
SPR E, X , P series modules and our Maxeon and Performance Product Line
are compatible with Transformer Less (TL) inverters, when used as an
ungrounded PV source.
No frame grounding requirements (including functional frame grounding),
but may be subjected to local regulation.
Functional system grounding of a polarity (positive or negative) is optional
and may be subject to local requirements.

Safety and Installation Instructions ‐ Document 001‐15497 Rev.X
Note: If you are installing an older Module Type than above
mentioned, please refer to different/previous applicable Safety and
Installation Manual.
If you are doing a frame grounding connection, avoid the direct
contact between Aluminum and Copper using an intermediate metal
like stainless steel or tin.
4.2 Series Connection
The modules may be wired in series to produce the desired voltage
output. Do not exceed the maximum system voltage specified in
module datasheet.
4.3 Parallel Connection
The modules may be combined in parallel to produce the desired
current output. Series string must be fused prior to combining with
other strings if the resulting maximum reverse current exceeds the
fuse rating as shown in the datasheets. Bypass diodes are factory
installed in the modules. Please refer to the applicable regional and
local codes for additional fusing requirements and limitations on the
maximum number of modules in parallel.

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 be mounted in locations that meet the
following requirements:
Operating Temperature: All Maxeon modules must be mounted in
environments within the following maximum and minimum operating
temperatures:
Maximum Operating Temperature +85 °C (+185 °F)
Minimum Operating Temperature ‐40 °C (‐40 °F)
Care should be taken to provide adequate ventilation behind 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, specially at mid‐day when the production is maximum.
Design Strength: Maxeon modules are designed to meet a positive or
negative (upward and downward, e.g. wind) withstanding test
pressure load and a negative (or downward, e.g. static load or snow
load) withstanding test pressure load, as per IEC 61215, when
mounted in the configurations specified in Section 5.2 and Tables 1.2
or 1.3 below.
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.
Additional authorized Operating Environments:
Modules can be mounted in the following aggressive environment
according to the test limits mentioned below
Salt mist corrosion testing: IEC 61701 Severity 6
Ammonia Corrosion Resistance: IEC 62716 Concentration: 6,667ppm
