1. INTRODUCTION
Thank you for using M600 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 a single photovoltaic module, consequently improving the
flexibility and reliability of the system.
This manual contains important instructions for the M600Micro-inverter and must be
read in its entirety before installing or commissioning the equipment. For safety, only
qualified technician, who has received train in gor has demonstrated skills can install
and maintain this Micro-inverter under the guide of this document.

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.
3.2 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.
See Appendix: Technical Data to check the environmental parameters to be
observed (degree of protection, temperature, humidity, altitude, etc.)
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.
