(*) The maximum series number of modules depends on the local conditions. These values are calculated under the condition of V
Under normal conditions, a photovoltaic module is likely to experience conditions that produce more current and / or voltage than reported at Standard Test Condi-
tions. Accordingly, the values of I
capacities, fuse sizes and size of controls connected to the module output.
Application Class
This module is rated as "Application class A" according to IEC61730.
"Application class A" means:
General access, hazardous voltage, hazardous power applications
Modules rated for use in this application class may be used in systems operating at greater than 50 V DC or 240 W, where general contact access is anticipated.
Modules qualified as application class A in IEC 61730 are considered to meet the requirements for safety class II.
Fire Rating
This module is rated as "Fire safety class C" according to IEC61730.
