2.3 TECHNICAL SPECIFICATIONS
A full list of mechanical and electrical technical
specifications for the PV modules can be
found in the Appendix section. Electrical test
data is according to standard test conditions
(IEC 60904-3).
Under normal conditions, a photovoltaic module
is likely to experience conditions that produce
higher current and/or voltage than reported at
standard test conditions. Accordingly, the values
of Isc and Voc marked on the PV module should
be multiplied by a factor of 1.25 when determining
component voltage ratings, conductor current
ratings, and size of controls (e.g. inverter)
connected to the PV output.
3. ELECTRICAL INSTALLATION
3.1 GENERAL INFORMATION
Ensure correct polarity when connecting
PV modules.
 Connectors are not waterproof when unmated.
When installing modules, connector should be
connected to each other as soon as possible or
appropriate measures should be taken to avoid
moisture and dust penetrating into the connector.
 Make sure that all connections are safe and
properly mated. An audible click should be heard
when mating connectors. The PV connector
should not be subjected to stress from the
exterior. Connectors should only be used to

5
produce the desired voltage output.
 The current of each module connected in
series should be the same.
 The maximum PV system voltage for that
circuit shall be calculated as the sum of the rated
open-circuit voltage of the series-connected
PV modules corrected for the lowest expected
ambient temperature.
3.4 PARALLEL CONNECTION
The solar modules may be combined in
parallel to produce the desired current output.
 When modules are combined in parallel, the
total current is equal to the sum of currents from
each module.
 The voltage of each module connected in
parallel should be the same.
 When connecting plural strings of modules in
parallel every series string or solar module must
be fused prior to combining with other strings.
 Abide with all applicable federal, state, and
local codes for additional fusing requirements
and limitations on the maximum number of solar
modules in parallel.
 Depending on national directives, additional
safety factors might be applicable for over current
protection.
A multiplying factor is required for
increased output of the PV modules.
Under normal conditions, a PV 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 PV module
should be multiplied by a factor of 125%
when determining component voltage
ratings, conductor ampacities, fuse sizes,
and size of controls to the PV output.
3.5 ELECTRICAL GROUNDING
 All work must be conducted in conformance
with all Federal, State, and local codes and
connect the circuit. They should never be used to
turn the circuit on and off.
Ensure cabling is adequately protected
from direct sunlight, dirt, debris,
moisture, and mechanical friction.
 Ensure that plug connections are secured
away from any water-accumulating surfaces. Use
UV-resistant cable ties to secure cables to the
mounting system. Cables should avoid exposure
to direct sunlight.
 Only use dedicated solar cable and suitable
connectors (wiring should be sheathed in a
sunlight-resistant conduit or, if exposed, should
be sunlight-resistant itself) that meet local
fire, building and electrical regulations. Please
ensure that all wiring is in perfect electrical and
mechanical condition.
3.2 WIRING REQUIREMENTS
 Mitrex recommends that all wiring be double
insulated with a minimum rating of 90°C (194°F).
 All wiring should use a flexible copper
conductor.
 Minimum size should be determined by
applicable codes.
 Mitrex recommends a minimum size of
10AWG.
 All Mitrex solar modules are connected via
MC4 connectors.
3.3 SERIES CONNECTION
 The solar modules may be wired in series to

6
standards.
 Do not drill any extra ground holes for
convenien¬ce this will void the modules warranty.
 Grounding connections should be performed
by a qualified electrician for the safety and
maintenance of the system in accordance with
all national, state and local electrical codes and
regulations and standards.
 Connect module frames together using
adequate grounding cables: Mitrex recommends
using 4-14 mm² (AWG 12-6) copper wire.
 All bolts, nuts, flat washers, lock washers and
other relevant hardware should be made of
stainless steel, unless otherwise specified.
In most of frames, holes provided for this
purpose are identified with a grounding
symbol (IEC 61730-1). Otherwise the
location is in the middle of long frame on
both side of the module. All conductive
connection junctions must be firmly
fixed.
Where common grounding hardware
(nut, bolts, washers) is used to attach a
listed grounding device, the attachment
must be made in conformance with
the grounding device manufacturer’s
instructions.
