Prior to installing modules please obtain information about any requirements and necessary approvals for the site, installation and inspection from the relevant authorities.
Microinverter System Installation
A PV system using Microinverters is simple to install. Each Microinverter easily mounts
on the PV racking, directly beneath the PV module(s). Low voltage DC wires connect
from the PV module directly to the Microinverter, eliminating the risk of high DC
voltage.Installation MUST comply with local regulations and technical rules.
Special Statement! An AC GFCI device should not be used to protect the dedicated circuit
to the microinverter even though it is an outside circuit. None of the small GFCI devices
(5~30mA) are designed for back feeding and will be damaged if back feed. In a similar
manner, AC AFCIs have not been evaluated for back feeding and may be damaged if back
feed with the output of a PV inverter.
WARNING: Perform all electrical installations in accordance with local electrical codes.
WARNING: Be aware that only qualified professionals should install and/or replace
Microinverters.
WARNING: Before installing or using an Microinverter,please read all instructions and
warnings in the technical documents and on the Microinverter system
itself as well as on the PV array.
WARNING: Be aware that installation of this equipment includes the risk of electric
shock.
Additional Installation components
· AC Male and Female Interconnection Connectors (sold separately)
· Sealing end caps(sold separately)
NOTE: Strongly recommend to install Surge protection Devices in the dedicated meter
box.
Required Parts and Tools from you
In addition to your PV array and its associated hardware, you will need the following
items:
· An AC connection junction box
· Mounting hardware suitable for module racking
· Sockets and wrenches for mounting hardware
· Continuous grounding conductor and grounding washers
· A Phillips screwdriver
· A torque wrench
WARNING: Wiring colour code can be different according local regulation,check all
the wires of the installation before connecting to the AC cable to be sure they match.
Wrong cabling can damage irreparably the microinverters,such an issue is not covered
by the warranty.
Mark the location of the Microinverter on the rack, with respect to the PV module
junction box or any other obstructions.
b. Mount one Microinverter at each of these locations using hardware recommended
by your module racking vendo

· Check applicable building codes to ensure that the construction or structure (roof, facade, support, etc.) can bear the module system load.
· CS-series solar modules have been qualified for Application Class A (equivalent to Safety Class II requirements). Modules rated under this class should be used in systems operating at voltage above 50 V or power above 240 W, where general contact access is anticipated.
· Atakale Solar Inc. modules have been certified as Type 1 or Type 4 according to UL 1703 andClass C according to IEC 61730-2, please refer to the datasheet or the product nameplate for the detailed types.
· Consult your local authority for guidelines and requirements for building or structural fire safety When installing modules, ensure the supporting roof has a fire resistant roof covering rated for the application. · The fire rating for this module is only valid when the product is installed as specified in the mechanical mounting instructio
The module is intended for use in general open-air climates, as defined in IEC 60721-2-1: Classification of environmental conditions Part-2-1: Environmental conditions appearing in nature - Temperature and humidity.
· Please consult the atakale Solar Inc. technical support department for more information on the use of modules in special climates, , such as an altitude greater than 2000 m.
Exposing modules to salt (i.e. marine environments) or sulfur (i.e. sulfur sources, volcanoes) incurs the risk of module corrosion. · Do not expose modules and their onnectors to any unauthorized chemical substances (e.g. oil, lubricant, pesticide, etc.), as modules may incur damages.
· Failure to comply with these instructions will void atakale Solar Inc. limited warranty
