Electrical Characteristics
The module electrical ratings are measured under
Standard Test Conditions (STC) of 1 kW/m² irradiance with
AM 1.5 spectrum and a cell temperature of 25 °C. Maxeon
modules have specific electrical characteristics as shown
on the datasheets.
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 I
on the module should be multiplied by a factor of 1.25 when
determining
component
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 not less than
4mm
2
. 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
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).

SPR 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.

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
Limited
The Maxeon
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
Minimum Operating Temperature
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
