General:
Solar modules generate electricity as soon as they are exposed to light. The voltage of a single module
is less than 50VDC. If several modules are connected in series, the voltages of the individual modules
accumulate and can pose a hazard.
The modules are qualified for application class A: Hazardous voltage (IEC 61730: > 50V; EN61730:
>120V), hazardous power applications (>240W), where general contact access is anticipated.
Modules qualified for safety through EN 61730-1 and -2 within this application class are considered to
meet the requirements of Safety Class II.
The maximum system voltage of solar modules connected to each other may not exceed 1000 VDC.
Under normal conditions, a photovoltaic module is likely to experience conditions that produce more
current and/or voltage than reported at standard test conditions. Sunny, cool weather and reflection
from snow or water can increase current and power output. Accordingly, the values of Isc and Voc
marked on this module should be multiplied by a factor of 1.25 when determining component voltage
ratings, conductor current ratings, fuse sizes, and size of controls connected to the PV-output.
Our products are not intended for use where artificially concentrated sunlight is applied to the
module.
