MBJ Mini Lab 4.0

The MBJ Mini Lab is designed as a lab system for quick and cost efficient in-depth quality analysis of photovoltaic panels. Integrated into a darkened container modules can be tested during the installation of a solar park. Directly on site, without further long and costly transport. It is ideal for testing a random sample before mounting.

The Mini Lab consists of an A+A+A+ MBJ LED Sun Simulator certified according to IEC 60904-9 Ed.3 for IV-curve measurement and a high resolution electroluminescence system. A electrical connection test and a bypass diode test is included as well.

Use it on site

Also designed as a lab system for quick and cost efficient testing of solar panels in a laboratory setup, it works perfectly on site.

It fits nicely into a 20' standard container which makes it easy to move the system from one location to the next, the darkened room needed for operation is already given. No matter if you are testing directly on site before installation or place it near the harbour for random sample testing, all is possible depending on your requirements.

 

The system provides

  • Power measurement
  • Electroluminescence
  • Diode test
  • Connection test

Powerful Software Package

The user-friendly Windows 10® based software installed on a 17” notebook provides a useful tool set especially for batch processing results of solar module measurements. It uses a database like structure to save results in great detail.

Store different parameter sets for different module types and referenze modules.

Measurements are organized in jobs making it a straight forward process to keep together what should be kept together. Default defect types, judgments and pre defined comment templates, together with the graphical repesentaion of results, make module judgment easy.

Don't have the time to judge modules while measuring - do it later in the office instead.

Create configurable PDF reports out of a job or modules of your choise. A report includes graphical data like the IV curve or EL defect images jsut as you needed it.

It is easy to use!

The modules are loaded vertically onto the roller system and connected manually. After the manual temperature measurement, the IV curve measurement is started and the result is displayed in the software. If required, the bypass diode test starts automatically directly after the power measurement.

Easy transfer to the second measurement: After the power measurement, the module is moved manually to the next position for EL image acquisition. No cables need to be unplugged. The electroluminescence image of the entire module is displayed.

The evaluation of the individual measurements is done directly or can be done later on the basis of the stored data. A PDF report of several measurements can be created directly from the software.

Certified by TÜV Rheinland

The Mini Lab uses the same high performance A+A+A+ LED sun simulator light source for power and IV curve measurement as the MBJ inline module production equipment.

The light source with the extended spectrum is certified by TÜV Rheinland according to standard IEC 60904-9 Ed.3 and offers the possibility to measure modules based on PERC and HJT cell technology due to its improved spectrum in the IR and UV range.

Benefit from the well-known advantages of LED technology such as a much longer light source life time, the stability of the light source over time, better measurement results through outstandingly stable repeatability and significantly reduced operating costs over the systems life time.

Combine the long light pulse with the innovative step wise IV-sweep when measuring the latest high capacitive cell technologies.
