CONNECTING SOLAR PANELS IN PARALLEL
The Samlex Expansion kits maybe used
to increase the solar energy available
to charge your batteries. Each Samlex
Expansion kit comes with a solar
panel, mounting hardware for the
solar panel and a set of MC male and
female branch connectors to parallel
the solar panel to your existing system.
1. If the existing panel is already
connected to the mating
connector on the pre-assembled
cables provided in the original
kit, remove this connection
using using a tweezer or any
other suitable tool.
2. Connect the Positive leads
(marked as ‘+’) from the two
solar panels to the suitable
mating branch connector (as in
Fig 9.1).
3. Connect the Negative leads
(marked as ‘-’) from the two
solar panels to the suitable
mating branch connector (as in
Fig 9.1).
4. Mate the MC branch connectors
to the corresponding mating
MC connector on the pre-
assembled cables provided with
your original kit.

If the additional solar panels are
required to be mounted at a distance
from the existing solar panel, a pair
of cables with a MC4 connector pre-
assembled at one end is provided.
1. Cut the cable pair to the
appropriate length.
2. Strip 0.25" of the insulation at
the blunt ends using a suitable
wire stripper.
3. Crimp the male and female MC4
connector to the blunt end of
the appropriate cable with a
suitable wire crimping tool.
4. Complete the connections as
shown in Fig. 9.2.
