Introduction
This manual provides important safety
instructions for the Sunflare PowerFit20 module
and should be read and understood in its entirety
prior to handling and installation. These modules
have been certified by CSA Group to UL1703 and
UL790 for installation on standing seam metal
roofing systems. These installation instructions
are valid for Sunflare PowerFit20 modules.
Installation, commissioning, servicing and repairs
to the module, and an array, should only be
carried out by qualified and authorized persons
in compliance with local and national electrical,
fire, and health and safety codes. If there are any
discrepancies between these instructions and the
applicable local or national codes, the local and
national codes take precedence.
These instructions are intended as a guideline
for professional solar system integrators and
installers only.
The PowerFit20 modules are not intended for
installation by unqualified end users. These
instructions are to be retained for future
reference in case of maintenance, ownership
change, or disposal.

General & Electrical
Safety Information
• Danger!
These modules can produce lethal
electrical voltages when connected in series.
Read all safety information prior to handling.
Failure to adhere to the following safety
guidelines can lead to arcs, fires, and electric
shock hazards.
• The module is considered in compliance with
UL 1703 only when the module is mounted
in the manner specified by the mounting
instructions below.
• Any module without a frame (laminate)
shall not be considered to comply with the
requirements of UL1703 unless the module
is mounted with hardware that has been
tested and evaluated with the module under
this standard or by field inspection certifying
that the installed module complies with the
requirements of UL 1703.
• The PV modules should only be used for the
purpose for which they are intended.
• Concentrated or artificial sunlight shall not be
directed onto the PV module.
• All work on the PV system should be
performed by qualified personnel only.
• Warning! Solar modules generate direct
current (DC) when exposed to light. Breaking
or opening a connection under load, i.e. when
current is flowing, can cause an electric arc
which will not self-extinguish.
• Never work on the system or module under
load.
• Always turn off and disconnect the inverter
or other loads before working on the system.
• Under normal conditions, a photovoltaic
module is likely to experience conditions
that produce more current and/or voltage
than reported at standard test conditions.
The requirements of the National Electrical
Code (NEC) in Article 690 shall be followed
to address these increased outputs. In
installations not under the requirements of
the NEC, the values of Isc and Voc marked on
this module should be multiplied by a factor
of 1.25 when determining component voltage
ratings, conductor ampacities, overcurrent
device ratings, and size of controls connected
to the PV output.
• Installing solar photovoltaic modules and
systems requires specialized skills and
knowledge. Do not attempt to install these
modules if not qualified to do so.
• Installation should only be performed by
qualified persons.
• The installer assumes all risks of injury that
might occur during installation, including but
not limited to the risk of electric shock.
