Wiring
Connect modules using the supplied Tyco type connectors in
series or parallel
configurations according to the “+” male
neutral (part 6-1394461-
2) or “-” female negative (part
1394462-4).
Only same type of Tyco connector shall be used in
connections 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
⁰
C 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.
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.
Bypass Diodes
3 Schottky type bypass diodes are pre-assembled in each
module.
Do not uninstall these diodes.

Series/Parallel Configurations
Series or Parallel configurations must be restricted to a
maximum system voltage of 600 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.
Refer to the electrical characteristics for the values of Isc
and Voc.
Series and Parallel interconnection restrictions
At standard conditions (AM1.5G, 25
⁰
C) 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 V
oc
temperature
coefficient (β), and module V
oc
.
Suniva recommends a maximum of 21 modules connected
in series to allow for a minimum ambient temperature - 40 C
to prevent an open circuit voltage in excess of 1000 V.
Suniva recommends a maximum of 12 modules connected
in series to allow for an ambient temperature - 40 C to
prevent an open circuit voltage in excess of 600 V.
At standard conditions (AM1.5G, 25
⁰
C) modules in parallel
without fuse protection are not allowed.
Suniva recommends that no modules be connected in
parallel without over current protection. 2 or more modules
may be connected in parallel with over current protection.
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.
Disclaimer of Liability
Suniva does not assume responsibility and expressly disclaims
liability for loss, damage or expense arising out in any way
connected with installation, operation, use or maintenance by
using this manual. Suniva assumes no responsibility for any
infringement of patents or other rights of third parties that may
result from use of the module. No license is granted by
implication or otherwise under any patent or patent rights.
Suniva reserves the right to make changes to the product,
specifications or this manual without prior notice.
