Universal J-Box for
Silicon Wafer Modules
Medium to
Highest Performance
The Y-Sol® Universal J-Box is a junction box featuring SMD diode technology.
It is designed according to the latest TÜV (VDE126-5) and UL requirements.
The J-Box can be connected to the panel either by spring force or soldering.
The J-Box design allows automated assembly in an assembly line.
Up to 6 bypass SMD diodes can be integrated as per customer requirements
(protection against overheating through shadowing).
Patent Pending*) on contact design.

Advantages
 Time-saving assembly and automated contacting due to spring contacts.
 Approx. 40% less heat development in the junction box as compared to
conventional radial diodes. This is due the use of SMD diodes.
 Material cost savings because resin filling of the J-Box is not required,
due to the sealing material in the J-Box lid.
 Space-saving installation due to one of the flattest designs on the market today
(compact height of 26.5 mm).
 Configuration according to customer requirements and delivery of complete
pre-assembled system with cables and plugs.
Cable Assembly Options
The Universal junction box is delivered completely assembled with cables and
Yamaichi connectors. Optional cable assemblies are Y-Sol3 (connector without locking)
or Y-Sol4 (connector with locking).

Bypass Diode
The Y-Sol® Thin Film J-Box is a junction box for the automatic assembly on
Thin Film wafer modules. It is designed according to the latest TÜV (VDE126-5)
and UL requirements.
The contacting is realised through spring loaded contacts when putting
on the lid. One bypass SMD diode can be integrated optionally as per
customer requirement (protection against overheating
through shadowing). Patent Pending*) on contact design.

Y-Sol3 and Y-Sol4
are ready-made solar cable assemblies, “ready-to-plug“ in your PV installation.
They are designed according to the latest TÜV (VDE126-3) and UL requirements.
The standard cables used are electron beam cross-linked Betaflam cables from
Studer. For long life and highest possible weather resistance.
Other cable types are available upon request.
Y-SOL3
Ø 3mm contacts for the transmission of power up to 30A
without locking
Y-SOL4
CABLE
Ø 4mm contacts
for the transmission of power up to 30A with locking
(Tool required to open the snap locking mechanism)
Customers Advantages
 Easy handling due to ready-made solar cable assembly.
 Safe power transmission due to high-quality contacts.
 Long life with weather resisting Studer Betaflam cables.
