Multimount Frame
These modules are available in three
configurations: the M configuration,
which includes the versatile
Multimount
cable; the D configuration, which
mounts directly to many surfaces
without additional hardware; and the
U configuration, which includes the
heavy-duty Universal frame and a
high-volume junction box with dual-
voltage output. In all configurations,
cells are laminated between sheets
of ethylene vinyl acetate (EVA) and
high-transmissivity low-iron 3 mm
tempered glass.
BP SX 20M
and BP SX 30M
The BP SX 20M and 30M are
general-purpose PV modules intend-
ed for single-module 12-volt applica-
tions with DC system voltage not
exceeding 30 volts. Output is via a
4.6m (15-foot) PVC-jacketed cable
which terminates in a low-profile
junction box on the module back.
Epoxy-potted in the box, module
electrical connections are sealed
against corrosion and effectively
strain-relieved.
The Multimount
SX 20M and 30M provides great
flexibility in mounting approach.
Oriented parallel to the edge and
back of the module, its dual chan-
nels accept the heads of 5/16 or
8mm hex bolts, allowing the module
to be mounted from the side or
back. Bolts may be located any-
where along the channels, a config-
uration which prevents them from
turning during tightening and allows
installation with just one wrench.
TM
frame and an output
TM
frame of the BP
BP SX 20 and BP SX 30 photovoltaic modules are part of BP Solar’s
SX module series, providing cost-effective photovoltaic power for DC
loads with moderate energy requirements. With 36 multicrystalline
cells in series, they charge batteries efficiently in virtually any climate.
Typical commercial applications of these modules, which generate nom-
inal maximum power of 20 watts and 30 watts respectively, include
remote telemetry, instrumentation systems, security sensors, signals,
and landbased navigation aids.
Direct-Mount Frame
BP SX 20D and 30D
The Direct-Mount frame of the BP
SX 20D and 30D enables these
modules to be mounted on many
surfaces (roofs, walls, etc.) without
additional mounting hardware. Their
electrical output circuitry and limita-
tions are identical to the M configu-
ration modules.
Universal Frame
BP SX 20U and 30U
The BP SX 20U and 30U are
designed primarily for industrial use
and other particularly demanding
applications. Their rugged Universal
frame is suitable for severe duty,
and exceeds the requirements of
all certifying agencies.

BP SX 20U and 30D
High-Capacity Versatile
Junction Box
The large (411cc, 25 cubic inches)
junction box of the U modules is
raintight (IP54 rated) and accepts
PG13.5 or 1/2” nominal conduit or
cable fittings. With its six-terminal
connection block, it enables most
system array connections (putting
modules in series or parallel) to be
made right in the junction box.
Optionally, this junction box can be
fitted with:
The BP SX 20U and 30U junction
box may be field-wired to provide
12V or 6V nominal output. Six-volt
modules are intended to support 6V
loads, and are not recommended as
series elements in higher voltage
arrays. The BP SX 20U and 30U are
approved by Factory Mutual
Research for application in NEC
