The open circuit voltage of the solar modules increases as the temperature decreas-
es, assuming constant irradiance. The open circuit voltage may not exceed the follow-
ing values, depending on the altitude:
Symo Advanced 10.0-3 - 12.0-3 208–240
0 to 11,154 ft
.

If the open circuit voltage exceeds the values stated above, the inverter may be dam-
aged and all warranty rights will become null and void as the inverter records the last
