Aros SIRIO EVO 5000 Manuel D'installation Et D'utilisation page 42

We recommend installing in an easily accessible location to facilitate periodic cleaning of the heat sink and to maintain a high
level of energy production.
Inverters can be set alongside one another, but
do not overlap them to avoid overheating the
higher positioned inverter.
If overlapping the inverters is necessary, leave
a space equal at least to the "Minimum
ventilation space".
In order to ensure a high level of productivity, it
is preferable to adopt staggered installation,
leaving a space equal to at least the "Minimum
distance" between one row of inverters and the
next.
