MBJ Mini Lab 4.0

The MBJ Mini Lab is designed as a laboratory system for a detailed quality analysis of photovoltaic modules on site. You can easily integrate it into your container, trailer or truck and thus be ideally equiped for your locations. The Mini Lab consists of a high-resolution electroluminescence system and a trippel A+ LED sun simulator for power and IV curve measurements. To be prepared for the larger module sizes coming in the near future, made from M6 and M12 size cells, the MiniLab 4.0 is available in three different sizes.

The sun simulator is certified by TÜV Rheinland according to IEC 60904 Ed3 norm. It is abel to measure modules based on new cell technologies like PERC and HJT more accurate due to its improved spectrum in the IR and UV range. In one day around 300 modules can be checked.

Designed for easy installation and operation

The operation of the MBJ Mini Lab 4.0 is very easy: Modules are loaded sunny side down into a carrier, connected and moved to the IV-Curve measurement position manually. With a handheld barcode scanner the transfer of the unic Module ID into the system is no problem. All results will be stored in the included database under this ID. After the IV-curve measurement the carrier is moved to the EL position by hand. With the set of fixed EL cameras the acquisition of a high resoulution images only takes a few seconds. The user-friendly Windows 10® based software, installed on a 17” notebook, allows the direkt final judgment of the EL images and the data evaluation of the IV curve.
