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.
Referring to the Technical Data to make sure the environmental conditions fit the
microinverter’s requirement (degree of protection, temperature, humidity, altitude, etc.)
To avoid power de-rating due to an increase in the microinverter internal temperature, do not
expose it to direct sunlight.
To avoid overheating, always make sure the air flow 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.
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 Microinverter underneath of the photovoltaic modules to make sure it works
in the shadow. If this condition cannot be met, it might trigger the inverter production de-
rating.
