Simple and Reliable
System Interconnection of
Individual Solar Modules
Right to the DC/AC
Converters
Market expansion of the formerly
regulated energy supply sector,
increased global environmental
awareness and governments
committing themselves to more
stringent environmental targets
have opened up new opportunities
for the photovoltaic industry.
Having served a niche market
in the past, the photovoltaics
industry now has the opportunity
to move into mass production,
realizing economies of scale and
gaining a greater market share
of the world’s energy mix.
Tyco Electronics will be con-
tributing to the establishment of
this environmentally-friendly
technology with the introduction
of its SOLARLOK connector
system.
SOLARLOK delivers a flexible
system solution for easy and
reliable interconnections from
photovoltaic modules to the
DC/AC converter. The entire
system concept is based on cost-
effective and reliable processing
of individual interconnection
system components. This
significantly reduces installation
costs of the solar energy system.
The junction box concept is
based on a flexible, open system
structure, which allows serial as
well as parallel interconnection
via direct wire connect or
separable connectors. Within the
junction box, up to six termina-
tion places rails are available for
photovoltaic foil connection.

–40 °C up to +125 °C
I
Voltage Rating up to 1800 V DC
I
Short circuit resistant
up to +250 °C
I
TÜV and UL approved
The male and female cable
coupler was designed for high
voltage and high current-carrying
capacity in addition to the well-
established IP 67 sealing require-
ment in the photovoltaic industry.
Mating safety is provided by
polarity keyed housings, fully
shrouded contacts, reliable high
cycle life, and squeeze to release
connection system. In addition,
a wide temperature range and ful-
fillment of worldwide standards
for photovoltaic connection
systems complement the robust
product specification.
The design of the male and
female receptacle for the junction
box and the DC/AC converter
follow the cable coupler “click
philosophy” for quick and secure
mating even in difficult mounting
positions.
If required by the customer, the
junction box can be delivered
pre-configured with diodes,
jumpers, plug connectors, and
solar cable pigtails.
All dimensions are in millimeters unless otherwise specified. All specifications subject to change.
