Installation of the equipment is carried out based on the system design and the place in which the
equipment is installed.
The installation is done by qualified installers and/or licensed electrician according
to the applicable local code regulations (National Electric Code (NEC), Canadian
Electric Code (CEC) and other local codes).
The connection of an inverter energy system to the electricity distribution network
shall be approved by the appropriate electrical distributor or authority having
jurisdiction.
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 Part 7: 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.

Certain conditions should be considered when choosing an installation
location at high altitudes:
•
Derating - Less efficient cooling; therefore, a greater likelihood of the device going into
derating because of high internal temperatures.
•
Electric Arc - Reduction in the dielectric resistance of the air that, in the presence of
high-operating voltages (DC input), can create electric arcs (electrical discharges) that
may reach the point of damaging the inverter.
All installations at altitudes of over 2000 meters/6562 feet must be assessed
case by case considering the aforesaid criticalities.
