A high-performance Tabber and Stringer equipped with a single welding tape (Single Track).

Description

Its innovative interconnection system allows the MTS 2500 Tabber to reach a net production capacity of 2400 cells per hour, making it the fastest in the market.

The MTS 2500 Tabber is designed to process cells of different technologies and sizes, and is capable of welding cells with up to 8 bus bar. Thanks to its compact design, it only requires 7.5m2.

The MTS 5000 solution is available for a net production of 4800 cells per hour, with more than 180 Mw per year.

Advantages

  • High production capacity, with 90 MW per year for a single Tabber.
  • A compact machine, requiring only 7.5 m2. It allows users to optimise the production space.
  • Homogeneous and stable production, in which all strings are manufactured in a single welding tape.
  • Capable of welding cells of up to 8 BB.
  • Compatible with different cell technologies and sizes.
  • Rupture rate lower than 0.2%

Main features

  • Contactless IR soldering so that stress is not generated in the cell.
  • Control of cell temperature to ensure good soldering.
  • Smart control of the process: the different parameters are adjusted automatically.
  • Vision control systems to check the quality of the cells so that defective cells can be removed.
