Suniva OPTIMUS Installation and Instruction Manual

Introduction

This manual provides safety and installation instructions for

Suniva photovoltaic modules, herein referred to as module(s),

with the followings model numbers:

• OPTXXX-72-4-YYY; Where XXX could be 285 to 350 in

increments of 5. YYY could be either 100, 101, 1B0, or 1B1

• OPTXXX-60-4-YYY; Where XXX could be 235 to 285 in

increments of 5. YYY could be either 100, 101, 1B0 or 1B1

To maintain the safety of yourself and others, carefully read the

entire installation and instruction sheet prior to installation and

operation. System safety and proper design should be ensured

by qualified personnel. Failure to comply with these

instructions will invalidate the Suniva Limited Warranty for the

module. For more information, please visit our website.

Safety

 Suniva modules produce electricity when exposed to light.

To avoid electric shock and injury, completely cover the front

of the module with an opaque material before making any

electrical connections and disconnect the module from all

electrical connections before any maintenance or cleaning.

 Only individuals trained in the principles of electricity and

electrical equipment should install modules.

 Modules must be installed in a manner compliant with the

National Electric Code (NEC) and/or all applicable standards

and codes.

 Use properly insulated tools and appropriate protective

equipment and work only in dry conditions.

 Protective gloves should be worn when handling modules to

protect against sharp edges and burns.

 Do not artificially concentrate sunlight on the module(s).

 Do not install the modules in an area where flammable gas

or material may be present.

 Do not remove any part installed by a qualified installer, or

disassemble the module in any way.

 Do NOT cut connectors off of the PV module

 Use original packaging to transport and store module.

 Avoid excessive loads, bending, and twisting of the module.

 Do not step/stand on the module.

 Avoid wearing metallic jewelry when installing or handling

the module to protect against electric shock.

 Do not leave the module unsupported or loosely fixed during

or prior to installation and avoid installing during heavy winds.

 Do not attempt to repair a broken or damaged module,

replace immediately to avoid fire danger and shock hazard.

Use caution when handling as damaged modules may

conduct electricity to the frame.

Long-term storage of PV modules

 PV modules should be stored, before and during

installation, in a manner to protect the unconnected

connectors from ingress of foreign elements such as: dust,

dirt, snow, ice, and water.

Product Information

 This solar module can be used in series and parallel array

configurations or as a stand-alone system.

 For IEC installations: This module is certified to IEC 61730-1

and IEC 61730-2 for application Class A and is rated for use

in systems operating at voltages greater than 50 VDC or 240

W, where general contact access is expected. And for Class

A applications this module meets requirements of Safety

Class II as defined by IEC 61140.

 The allowable operating temperatures range of the module is

185 ⁰F to -40 ⁰F (85 ⁰C to -40 ⁰C).

Serial Number

 The structure of the module serial number provides the

following information:

Example: SJWSH00011103310017

S-JWSH-0001 – 11– 03 – 31 - 0017

A-BBCC-DDDD-EE-FF-GG-HHHH

A: Manufacturer; BB: Factory; CC: Factory Location

DDDD: Engineering Number; EE: Year of Production; FF:

Month of Production; GG: Date of Production; HHHH: 4 digit

sequence 0 to 9999 for sequential production starting on

each new day of production at 0001.

Electrical Characteristics

 See tables at end of installation manual for electrical

parameters.

 The electrical characteristics are within ±10 percent of the

indicated values of I

, V

, and P

MAX

under standard test

conditions; irradiance of 100 mW/cm

, AM 1.5 spectrum, and

a cell temperature of 25°C (77°F).

 Maximum series fuse rating is 15 A

 This module is rated for use in systems of up to 1000 V for

TUV/IEC and up to 1000 V for UL

 Under normal conditions, a photovoltaic module is likely to

experience conditions that produce more current and/or

voltage than reported at standard test conditions.

Accordingly, the values of I

and V

marked on this

module should be multiplied by a factor of 1.25 when

determining component voltage ratings, conductor

ampacities, fuse sizes, and size of controls connected to the

PV output.

 Per NEC: “Refer to Section 690-8 of the NEC for an

additional multiplying factor of 125 percent (80 percent

derating) which may be applicable.”

Temperature Coefficients

Power γ, Pmax (%/°C) - 0.420

Voltage ß, Voc (%/°C) - 0.335

Current α, Isc (%/°C) + 0.047

NOCT C 46 +/- 2

Mounting Overview

 Mounting design and installation should be performed by

trained professional and must conform to local codes.

 Select a site and configuration that maximizes direct sunlight

exposure and eliminates or minimizes shadowing.

 Avoid small tilt angles to prevent the accumulation of

dirt/debris along module edge.

 Improper mounting of the module(s) can lead to damage or

injury and will void the warranty. Do not drill additional

mounting holes into module frames. This will void the

warranty.

 The module(s) should be fixed in a manner that withstands

all expected loads, including those caused by wind, snow

and ice. Verify by certified engineer.

 Orient the module junction box in such a way and provide

clearance between the module frame and mounting surface

to ensure that water cannot build up at the junction box and

so the junction box does not contact the mounting surface.

 The PV module is listed as Type 2 under the revised

ANSI/UL 1703 standard.

If the module is to be mounted to a roof of a building, the assembly must be mounted over a fire resistant roof covering suitable for the application. A slope less than 5 in/ft (127 mm/305mm) is required to maintain the fire class rating. Mounting Instructions It is acceptable to mount this module using bolts or clamps to secure module to a structure on a roof, building or ground.

Grounding using Screw and Washer Assembly Attach the grounding conductor to the module frame through at least one of the two grounding holes, See Figure 3. Figure 3: Grounding Hole Location grounding applications using a solid 6 to 12 AWG un-insulated ground wire. It is attached to grounding hole on module frame, Figure 3, by an integrated, 8-32 in threaded post and nut. Locate the grounding hole on the underside of the module frame (1). Insert the threaded post end of the wire bolt into the hole (2).
PAGE 4
(Or) Use of Grounding Lug with Nut The grounding bolt manufactured by Burndy (Part number: CL501TN) is UL listed and designed for module grounding applications using a solid 4 to 14 AWG un-insulated ground wire. Locate module grounding hole, Figure 3. Using a 5/16 open ended wrench, thread #10-32 self-threading screw through the grounding hole to open up the hole size and remove. Assemble a #10-32 bolt (2) through the grounding lug (1) and into the module grounding hole.

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 (β), and module Voc.
