While connecting the modules in series, please pay attention to
the maximum system voltage.
While connecting the modules in parallel, please pay attention
to the maximum allowed current of each component.
Do not connect more than 21 modules in series and no more
than 2 modules / strings in parallel.
Please pay attention to the electrical charcteristics of your
inverter.
To reduce indirect lightning strikes, when laying the string
cables the area of the loops must be kept as small as possible.
It is highly recommended to use adequate DC fuses for each
string.
The necessary electrical connections to the
main power grid may only be performed by a
qualified electrician.
Never disconnect module connections when
current is flowing, or an arc will form. Break
circuit first at a load-break rated disconnect.
