TENKA POWER GUARD 2-2 - Generator junction box for MAXIMUM SAFETY for PHOTOVOLTAIC SYSTEMS and your home!
The Tenka Power Guard PV generator junction box offers a reliable and flexible solution for photovoltaic systems with up to 1,100 V DC and 40 A. It supports up to 2 independent MPPT trackers and 4 PV strings, which enables optimum system flexibility. The integrated overvoltage protection of types T1 + T2 ensures maximum protection of the system against electrical overvoltages. Thanks to the IP65 protection class, the junction box is suitable for both indoor and outdoor use. The simple installation and universal compatibility with all common inverters and solar modules make it an ideal choice for private and commercial PV systems.

Thanks to the IP65 protection class, the Tenka Power Guard junction box is suitable for both indoor and outdoor use. The robust housing is made of UV-resistant polycarbonate and has an impact resistance of IK10, which ensures a long service life and high resistance to environmental influences. The design offers additional protection against dust and water.

Flexibility in system design

The Tenka Power Guard supports up to 2 independent MPPT trackers and can integrate up to 4 PV strings. This flexibility enables optimal adaptation to the requirements of modern photovoltaic systems and increases the efficiency of the system. Especially in complex installations, the support of multiple MPPTs ensures that energy production is maximized.

Surge protection type 1 + 2

The integrated type 1 + 2 overvoltage protection ensures the best possible protection against overvoltages caused by lightning strikes or other electrical faults. This minimizes the risk of system failure and protects valuable components of the photovoltaic system. The protection level is 3.5 kV and the total discharge surge current is 40 kA.
The Tenka Power Guard is compatible with all common inverters and solar modules, which makes it very versatile. It is supplied as a complete installation kit, including all necessary mounting and connection accessories. The MC4-Staubli connections and the wall mounting brackets facilitate installation and make the junction box particularly user-friendly.

Tenka Orion technology - more performance thanks to patented Tenka Nanotech coating

Tenka Orion technology increases performance by up to 15% thanks to millions of small prisms on the cell surface!

Tenka nanotech coating for more performance

Tenka Orion technology redefines efficiency in photovoltaics. At its heart is the patented Nanotech coating, which enables an exceptionally high light yield thanks to millions of tiny prisms on the cell surface. Even weak or diffuse light is efficiently captured and converted into electricity - a clear advantage in changing weather conditions or limited light incidence.

Tenka Orion modules achieve measurably higher energy yields than conventional modules, particularly at off-peak times and when the sky is overcast. This technology maximizes the energy yield per square metre and makes roofs with limited space economically viable. At the same time, it reduces installation costs as fewer modules are required for the same output.

All the advantages at a glance:

  • The patented Tenka Nanotech coating increases the energy production of each individual solar cell through millions of ultra-fine prisms.
  • Millions of microscopically small prisms on cell surfaces guarantee optimum light absorption and maximum energy yield.
  • Tenka uses only the highest quality and selected materials for long-term efficiency and reliable module performance.
  • The increased module efficiency enables significantly more PV output on the same area at significantly lower installation costs.
  • Reliably high energy yields guaranteed even in weak sunlight, in the morning and evening and on cloudy days.

The combination of nanotechnology and high-quality cell architecture makes Tenka Orion an ideal solution for all areas of application - from private house roofs to large open-space systems. The optimized use of light noticeably extends the daily generation time, which creates significant additional yields, especially in the morning and evening hours.

Tenka Orion technology also impresses with long-term use: low degradation, high material quality and constant performance ensure long-term investment security. Tenka Orion modules thus set new standards for sustainable and powerful PV systems - both technically and economically.
