Tab. 1 Date and limit values of the circuit
*Values refer to the module with the highest efficiency
** If more than three strings are to be connected in parallel they must be protected by using surge
voltage protectors
Under normal conditions, a photovoltaic module is likely to experience conditions that pro-
duce more current and/or voltage than reported at standard test conditions. Accordingly the
values of I
sc
and V
oc
marked on the module should be multiplied by a factor of 1,25 when de-
termining component voltage ratings, conductor current ratings, fuse sizes and size of controls
connected to the PV output.
The modules are dimensioned for use in application class A to EN 61730 / IEC 61730 (general
access, hazardous voltage >120 V DC EN 61730 / > 50 V DC IEC 61730).
