General Informa-
tion about Solar
Modules
In order to select suitable solar modules, observe the following points:
-
The open circuit voltage of the solar modules increases as the temperature
decreases, assuming constant irradiance. The open circuit voltage may not exceed
the following values, depending on the altitude:
Symo Advanced 10.0-3 - 12.0-3 208–240
0
to
11,154
ft.
(0
to

-
If the open circuit voltage exceeds the values stated above, the inverter may be
damaged and all warranty rights will become null and void as the inverter records
the last DC voltage in the system meaning that non-compliance with the maximum
permitted limits can be checked.
-
Note the temperature coefficients in the solar module data sheet
-
More exact data for sizing the solar modules for the particular location can be
obtained using calculation tools such as the Fronius Solar.configurator (available at
https://www.solarweb.com).
-
See NEC table 690.7 for the appropriate voltage adjustment factor for crystalline sil-
icon solar modules, or use the manufacturer's specified voltage coefficients.
