Wiring
Connect modules using the supplied connectors in series or
parallel configurations according to the “+” positive or “-
”negative.
Use only same type of connector, to ensure the reliability of
the electrical connection.
For conductor utilize suitable “Wet or Dry” type sunlight
resistant cable (PV-Wire, or USE-2 type) with temperature
rating of 90 ⁰C or higher and sized 12 AWG or larger.
Paralleled configurations may require greater wire size to
accommodate increase current. Ensuring proper conductor
sizing is the responsibility of the installer.
Maintain a minimum bending radius of 50 mm at all locations
along the cable. Pay particular attention to the exit point from
the junction box and interconnection point between modules.
Junction Box
Do not open the junction box or change inter-module wiring.
All wiring connections are made in the factory and doing so
may void the warranty.
Verify junction box lid is firmly closed when installing panel.
Do not alter the connectors. Doing so will void the warranty.
Bypass Diodes
3 Schottky type bypass diodes are pre-assembled in each
module in parallel with cell strings.
Do not uninstall these diodes.
Bypass Diode Ratings: V

Series/Parallel Configurations
Series or Parallel configurations must be restricted to a
maximum system voltage of 1000 VDC (UL) or 1000 VDC
(IEC).
Voltage and current are temperature dependent and
systems should be designed to allow for variations due to
local conditions.
The voltage of modules in series connections will be equal to
the sum of the individual voltages.
The current of modules in parallel connections will be equal
to the sum of the individual currents.

OPTXXX-##-4-1YY IEC & UL EN Suniva, Inc. SI&IM _9 Rev 9 Pa e 5
Refer to the electrical characteristics for the values of Isc
and Voc.
Series and Parallel interconnection restrictions
At standard conditions (AM1.5G, 25⁰C) the number of
allowable modules in series is equal to the maximum system
voltage divided by the Open Circuit voltage. The number of
modules in series should be constrained by the expected
minimum ambient temperature, module Voc temperature
coefficient (), and module Voc. Suniva recommends the
following to allow for a minimum ambient temperature of -40
C.
To prevent an open circuit voltage in excess of 1000 V:
For OPTXXX-60 Series modules: 21
For OPTXXX-72 Series modules: 17
To prevent an open circuit voltage in excess of 600 V:
For OPTXXX-60 Series modules: 12
For OPTXXX-72 Series modules: 10
Overcurrent protection (such as fuses) must be used when
connecting three (3) or more strings in parallel.
Over Current Protection
Series or parallel connections of modules or strings must be
provided adequate over current protection such as a
recognized circuit breaker or fuse meeting minimum
requirements listed in the Product Information section of this
manual and be certified and properly rated. System design
and protection for any series/parallel configuration must be
verified by a certified engineer and is the responsibility of the
system integrator as currents may exceed 1.25 times I
SC
under some conditions.
Disconnection Under Load
Do NOT disconnect or connect module under load.
Modules will produce electricity even under low light
conditions. Treat modules as if they are live electrical
equipment.
To avoid electric shock and injury, completely cover the front
of the module with an opaque material and disconnect the
module from all electrical connections before disconnecting
or connecting module wiring.
Maintenance
Maintenance is recommended to ensure optimal performance:
Depending on local conditions, periodically inspect and clean
the surface of the module with water and a soft cloth or
sponge when the modules surface becomes dirty and rain
water is insufficient to remove dirt/debris.
Never clean the modules during the middles of the day when
the glass is hot to avoid injury.
Never scratch or rub away any dirt when the modules are
dry.
Check the electrical and mechanical connections annually to
ensure all the connections are secure, tight, clean and free
of corrosion.
To prevent PV module frame damage due to the formation of
ice-dams, excessive amounts of snow and ice should be
cleaned off the PV modules and not allowed to accumulate
and remain on the modules indefinitely
