All measures recommended by the solar module manufacturer for maintaining solar mod-
ule properties must be followed.
Follow all grid operator regulations regarding grid power feed and connection methods.
Location Selec-
tion
Please note the following criteria when choosing a location for the inverter:
The inverter is suitable for indoor installation.
The inverter is suitable for outdoor installation.
Because of its NEMA 4X protection class, the inverter is not susceptible
to hose water on any side and can also be operated in moist environ-
ments. However:
In order to keep inverter heating as low as possible, do not expose the
inverter to direct sunlight. The inverter should be installed in a protected
location, e.g., near the solar modules or under an overhanging roof.
IMPORTANT! The inverter must not be installed or operated above an
altitude of 11,154 ft. (3400 m).
The maximum permissible DC voltage of the inverter depends on the al-
titude.

at an altitude of:
Symo 10.0-3 – 12.0-3 208–240
0 to 11,154 ft ( 0 to 3400 m). = 600 V
Symo 10.0-3 – 24.0-3 480
0 to 6561 ft ( 0 to 2000 m). = 1000 V
6531 to 8202 ft (2000 to 2500 m). = 950 V
8202 to 9842 ft (2500 to 3000 m). = 900 V
9842 to 11,154 ft (3000 to 3400 m). = 850 V
The output power reduces when the device temperature is too high, and
this may occur earlier than normal at increased altitudes.
Do not install the inverter:
- where it may be exposed to ammonia, corrosive gases, acids, or
salts
(e.g., fertilizer storage areas, vent openings for livestock stables,
chemical plants, tanneries)
During certain operating phases the inverter may produce a slight noise.
For this reason, it should not be installed in an occupied living area.
