MEASURING EXAMPLES THAT CONVINCE YOU

  • Measurement of the distribution of currents in connected Shingled Solar modules
  • Analysis of the quality of individual adhesive points by simply stroking over
  • Quick detection of hidden shunts and other inhomogeneities
  • Optimization of series resistors and Shingle concepts
  • Use in production and free field

  • Measurement of a solar cell
  • The right busbar is not connected to the cross connector

  • Measurement of a cell in the module network
  • The solder points become visible in the By-component of the magnetic field
  • Some solder joints are missing
  • It can also be determined whether the soldering points are in the middle of the pad or offset.

  • Measurement of a solar cell with microcrack
  • The crack is clearly visible
  • No soldering points are visible below the crack
  • The crack has cut through the busbar

  • Measurement of three cylindrical Li-Ion batteries during a charging process
  • The right battery shows an abnormality
  • The changed magnetic field indicates a locally changed current flow
  • MFI allows the detection of defects in accumulators

  • Measurement of a pouch cell during the charging process
  • MFI makes it possible for the first time to visualise the flow of electricity

  • Measuring a crack in the metal with a handheld device
  • Measuring signal 3-4 orders of magnitude via signal-to-noise ratio
  • Live measurements possible
