7.1.2 Ambient Conditions
► The solar inverter has an IP65 degree of protection and can be
installed indoors or in protected outdoor areas.
► Note the
operating temperature range at full power without
derating
and the
maximum operating temperature range
.
When the first operating temperature range is exceeded, the
solar inverter reduces the amount of power generated.
–
Be sure to observe the specified minimum clearances to
walls and other solar inverters when installing the device
(see
Fig. 7.2, p. 25)
.
–
Do not install two solar inverters directly above one
another.
–
Avoid direct sunlight.
–
Ensure adequate air circulation. Hot air must be able to
dissipate upward. For this reason, installation directly
under a closed roof is not recommended.

► Avoid heavy soiling. Dust can impair the performance of the
device.
► Protect the solar inverter from heavy rain and snow deposits.
7.1.3 Consideration of Asymmetrical Grid Load
The use of a SOLIVIA Gateway M1 G2 is mandatory for some
installation types.
This applies, for example, to installations where several single-
phase solar inverters feed into the same phase and an impermis-
sible asymmetrical grid load can occur if a phase fails.
Fig. 7.3, p. 26
shows an example of such an installation for
Germany. In Germany, the asymmetrical grid load may not exceed
4.6 kW.
The SOLIVIA 11 EU G4 TR three-phase solar inverter does not
experience this problem, because it controls the feed-in internally
and always distributes the fed-in power evenly among all three
phases.
The situation is different for single-phase solar inverters. If the
phase fails, an asymmetrical grid load greater than 4.6 kW can
occur.
In this case, the Gateway controls the feed-in via the RS485 inter-
face and ensures that an impermissible asymmetrical grid load
cannot occur.
If a Gateway is used to balance asymmetrical grid loads, you must
activate the "asymmetrical grid load balancing" function on each
single-phase solar inverter during initial commissioning.
If the RS485 connection between the Gateway and a single-phase
solar inverter is interrupted, the function switches off the solar
inverter after a specified time for safety reasons.
