Electrical Installation
Parallel Connection
The solar modules can be connected in
parallel to receive a higher output cur
rent.
Every string or solar module in series
must be fused prior to combination with
other strings. At its factory, LG Electronics
preinstalls bypass diodes in the solar
modules. Observe the corresponding
regional and local directives regarding
additional requirements for fuses and
limiting the maximum number of solar
modules in parallel connection.
Parallel connection for increasing the system current
The maximum number of solar modules
in parallel connection without additional
precautions such as fuse or blocking di
ode is one module string. The number
of module strings in parallel connection
is not restricted if relevant precautions
have been taken for blocking the reverse
current; meaning, for instance fuses to
protect the solar module and the cable
from overcurrent, or blocking diodes for
unequal string voltage.
The solar modules or module strings
should be connected in parallel if the
system is in shade.
