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 decreas-
es, assuming constant irradiance. The open circuit voltage may not exceed the follow-
ing values, depending on the altitude:
- 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
AC & DC = aluminum cables (Al)
The following wire combinations can be used for wiring.
Select a sufficiently large cable cross-section based on the actual device output!
