1. Introduction
Thank you for using SMP300/600 Micro-Inverter! This Micro-Inverter system is the
world’s most technologically advanced inverter system with benefits of efficient, flexible,
safe and reliable for use in utility-interactive applications.
This system is composed of a group of Micro-inverters that convert direct current (DC)
into alternating current (AC) and feeds it into the electric grid. Different from systems
that photovoltaic modules are subdivided into strings and controlled by one or several
inverters, this system is built for the incorporation of a Micro-inverter for each
photovoltaic module. Each Micro-inverter works independently of the others to
guarantee maximum power of each photovoltaic module. This setup enables direct
control over the production of as single photovoltaic module, consequently improving
the flexibility and reliability of the system.
This manual contains important instructions for the SMP300/600 Micro-inverter and
must be read in its entirety before installing or commissioning the equipment. For safety,
only qualified technician, who has received training or has demonstrated skills can
install and maintain this Micro-inverter under the guide of this document.

2.2.Installation warnings
The SMP300/600 Micro-inverter is designed and tested according to international
safety requirements. However, certain safety precautions must be taken when
installing and operating this inverter. The installer must read and follow all instructions,
cautions and warnings in this installation manual

4
➢All operations including transport, installation, start-up and
maintenance, must be carried out by qualified, trained personnel.
➢Before installation, check the unit to ensure absence of any transport
or handling damage, which could affect insulation integrity or safety
clearances. Choose installation location carefully and adhere to
specified cooling requirements. Unauthorized removal of necessary
protections, improper use, incorrect installation and operation may
lead to serious safety and shock hazards or equipment damage.
➢Before connecting the Micro-inverter to the power distribution grid,
contact the local power distribution grid company to get appropriate
approvals. This connection must be made only by qualified technical
personnel .It is the responsibility of the installer to provide external
disconnects switches and Over current Protection Devices (OCPD).
➢When the photovoltaic array is exposed to light, it supplies a D.C.
voltage to the inverter
➢Only one photovoltaic module can be connected in the input of the
inverter. Do not connect batteries or other sources of power supply.
The inverter can be used only if all the technical characteristics are
observed and applied.
➢Do not install the equipment in adverse environment conditions such
as flammable, explosive, corrosive, extreme high or low temperature,
and humid. Do not use the equipment when the safety devices do not
work or disabled.
➢Use personal protective equipment, including gloves and eye
protection when working.
➢Inform the manufacturer about non-standard installation conditions.
➢Do not use the equipment if any operating anomalies are found. Avoid
temporary repairs.
➢All repairs should be carried out using only qualified spare parts, which
must be installed in accordance with their intended use and by a
licensed contractor or authorized Omnik service representative.
➢Liabilities arising from commercial components are delegated to their
respective manufacturers.
➢Anytime the inverter has been disconnected from the power network,
use extreme caution as some components can retain charge sufficient
to create a shock hazard. Prior to touching any part of the inverter use
care to ensure surfaces and equipment are at touch safe temperatures
and voltage potentials before proceeding.
➢Omnik accepts No liability for damage from incorrect or careless
operation
➢Electrical Installation & Maintenance shall be conducted by licensed
electrician and shall comply with Australia National Wiring Rules

5. Prepare for installing
5.1.Transport and inspect
Omnik packages and protects individual components using suitable means to make
the transport and subsequent handling easier. Transportation of the equipment,
especially by road, must be carried out by suitable ways for protecting the components
(in particular, the electronic components) from violent, shocks, humidity, vibration, etc.
Please dispose the packaging elements in appropriate ways to avoid unforeseen
injury.
It is the customer’s responsibility to examine the condition of the components
transported. Once receiving the Micro-inverter, it is necessary to check the container
for any external damage and verify receipt of all items. Call the delivering carrier
immediately if damage or shortage is detected .If inspection reveals damage to the
inverter, contact the supplier, or authorized distributor for are pair/return determination
and instructions regarding the process.
5.2.Check installation environment
Installation of the equipment is carried out based on the system design and the place
in which the equipment is installed.
➢The installation must be carried out with the equipment disconnected from the
grid(power disconnect switch open) and with the photovoltaic modules shaded or
isolated.
➢To avoid unwanted power derating due to an increase in the internal temperature
of the inverter, do not expose it to direct sunlight.
➢To avoid overheating, always make sure the flow of air around the inverter is not
blocked.
➢Do not install in places where gasses or flammable substances may be present.
➢Avoid electromagnetic interference that can compromise the correct operation of
electronic equipment.
➢To ensure the safety of personnel and equipment needed to mount the PV array
is connected and grounded with other conductor casing.

5.3.Installation position
When choosing the position of installation, comply with the following conditions:
Install only on structures specifically conceived for photovoltaic modules (supplied by
installation technicians).
Install Micro-inverter underneath the photovoltaic modules so that they work in the
shade.
If this condition cannot be met, the inverter could undergo derating.

Step 1. Install Micro-inverter
Mark the approximate center of photovoltaic module on the frame and install the
Micro-inverter with the LED side facing upwards.
The Micro-inverter must be under the module, out of long-term
exposure to direct sunlight or rain.
First Type of Installation (Wall bracket hole):
There are two wall bracket holes in each Micro-inverter as shown in Fig.1 and
Fig.2.Use a pair of screws and nuts to install the micro-inverter onto the bracket as
shown in Fig.5.
Fig.5. Installation Example (Wall Bracket Hole)

Step 2. Connecting AC End Cables
Connect the AC end cables. We provide an AC connecter for each micro-inverter as
shown in Fig.10.
Fig.10. AC Connecter
Separate the AC connecter as shown in Fig.11.
Fig.11. Separate the AC connecter
Use 12 AWG (4mm2) copper wire for AC end cables. Use only solid wire or stranded
wire.
The definition of the AC connecter is shown in Fig.12.
Port 1(Brown/Red): Live
Port2(Yellow-Green): Ground
Port3(Blue/Black): Neutral

Open the protective cover of the connector as shown in Fig.14. Plug the AC connectors
of the AC End Cable into the micro-inverter as shown in Fig.15. Make sure the
protective cover of the unused AC connector to be closed.
Fig.14. Open the protective cover of the connector
Fig.15. Connect AC Cable of Micro-inverter
To prevent electrical hazards, all the connection operations must be
carried out with the equipment disconnected from the grid.
Pay special attention and ensure not to reverse the phase with the neutral!

16
The installation technician is responsible for selecting a cable with the
appropriate length and cross section.
Step 3. Install Photovoltaic Modules
Install the photovoltaic modules, and connect the DC cables of the modules to the
corresponding DC input side of the Micro-inverter.
Fig.16. Connect DC Cables
The recommended installation needs keeping the Micro-inverters
underneath the photovoltaic modules, so that the Micro-inverters can
operate in the shade. Direct sunlight may cause damage to the Micro-
inverters.
Each module must be connected to the Micro-inverters with a DC
cable having a length of less than 3m.
Check the LED on the side of the micro-inverter. The LED flashes green and red at
start up.
