TRI-KA – The mobile I-V Curve Tracer

Mobile portable measuring instrument 

The new TRI-KA not only identifies the current voltage curves of module strings, but also of individual photovoltaic modules. The I-U characteristic curve, output, short-circuit current and open-circuit voltage are recorded by a 16 bit processor. During each measurement the TRI-KA adjusts the measuring range and sample rate optimally. The device is easily and intuitively operated using the menus on the colour touch screen. The characteristic curve measured by the TRI-KA can be converted to a STC characteristic curve based on the values measured by the sensor TRI-SEN and displayed. In addition, the STC ideal characteristic curve of the manufacturer can be displayed, due to the integrated module data base.

Wireless sensor

Without contact, the wireless sensor TRI-SEN measures the cell temperature, the angle of inclination and the irradiation at the solar module level. The measured values are wirelessly transferred directly to the main instrument, the TRI-KA. The reference cell for the measuring of the irradiation can be either a monocrystalline or a polycrystalline cell.

Evaluation software

The evaluation software was also completely overhauled. The TRI-KA software can evaluate, manage and store the measured module data on the PC. With a few steps of the guided Wizard, the measured data is saved to the respective customer or system directory. Further measurements of the same system can then be added, sorted by date, and compared with the software.
