4.1 Installation Site Requirements
Floor
The foundation must guarantee solid and safe positioning of the inverter. The foundation must provide
the load-carrying capacity necessary to cope with the weight of the inverter. The inverter cabinet must
be installed on a level surface. Any existing unevenness, depression or slope must be corrected prior
to installation.
Wall Clearances
When installing the inverter, appropriate distance to the wall for minimum passageways, escape
routes, and ventilation have to be observed. Appropriate specifications for each type of inverter are
contained in the Sunny Central Installation Requirements (separate document).
Inverter Protection Rating / EMC / Sound Levels
The Sunny Central is suitable for a dry, dust-reduced environment, according to IP20 protection rating.
With regard to the EMC emissions and the noise level, the Sunny Central inverter is conceived for
setup in an industrial environment.
4.2 Electrical Operating Room
For the installation and connection of the Sunny Central central inverters, observe DIN VDE 0100,
part 729, part 731. The requirements for the electrical operating room for the installation of high-
voltage systems up to 1 000 V as well as the requirements for passageways and escape routes are
included therein.
Sunny central installation requirements
Each Sunny Central has individual installation requirements. These can be ordered at any
time from SMA Solar Technology and have to be observed for project planning and
preparation of the installation site.
Selecting switch cabinet units
During installation and internal cabling, make sure the switch cabinet units have the same
series number.
Sunny central installation location
The Sunny Central should be installed in an electrical operating room.
