Sunny Boy 2500U

7 Technical Data

Input (PV panel)
Maximum open circuit voltage of the PV panel
WARNING: It is essential to comply with the respective input voltage
range which varies depending on the type and number of PV modules
used.
WARNING: The maximum open circuit voltage of the PV panel may not ex-
ceed the specified maximum input voltage of the Sunny Boy.
The open circuit voltage of the PV panel depends on the temperature of its cells and
on the respective solar radiation. The highest open circuit voltage of the PV panel oc-
curs when the temperature of the cells is at its lowest point. Therefore it has to take
into account the lowest possible ambient temperature of the PV panel when planning
the PV plant. Based on this temperature and knowing the type of PV modules used
you can then determine the maximum open circuit voltage of the PV panel. You can
enter these data into our EXCEL
missible input voltage of the Sunny Boy is not exceeded under any possible operating
conditions. You will find this tool in the Internet for download at:

WARNING: The MPP-voltage of the connected PV-modules may not fall
below the specified range at 158 °F (+70 °C) (V
range).
NOTE: The Sunny Boy can tolerate a current higher than the specified
current as long as the voltage is within the specified range.
