4.3Space Distance Required
If the microinverters are installed on a concrete roof or steel roof, the communication with the DCU may
be slightly affected. Under such installation conditions, it is better for the microinverters to be installed
50cm above the roof. Otherwise, more DCUs may be required to ensure the communication quality
between the DCUs and the microinverters.
4.4Preparation
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.
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
