PVPM 1000CX 1000CX40Peak Power Measuring Device and Curve Tracer for Photovoltaic Modules The PVPM 1000CX / 1000CX40 enables the measurement of the I-V-curve of photovoltaic modules as well as of strings or arrays. By a newly developed procedure the device can measure and calculate the peak power Ppk, the Rs and Rp directly at the installation site of the PV system. Calculation results and the diagram can be displayed on the internal colour TFT-display. The peak power is the power of a module under Standard Test Conditions (STC) [1]. So far the very complex measurement of the peak power was possible only in particularly suited laboratories. By a patented procedure [2], which was developed by Professor Wagner at the University of Applied Sciences Dortmund, the measurement with the PVPM can easily be performed. So the quality control of a PV system can be executed fast and economically. This simple and meaningful check in practice serves the certainty of the customer and also that of the installer. Beyond that the measured I-V-curves permit further explanations about the electrical characteristics of the verified module or string. That is why the PVPM 1000CX / 1000CX40 is suitable as an instrument in research and for development purposes as well. precise I-V-curves due to capacitive load integrated module database integrated customers database easy operation over touch screen high-contrast and highly dissolving colour TFT display self-sustaining mobile operation (no other devices required) everlasting and waterproof plastic housing 32 bit miniature industrial PC internal battery power supply including charge controller external power pack with wide range input (world-wide use), charge / continuous operat. data transfer and further analysis of measured data on a PC (isolated USB connection) with PC: continuous measurements with selectable time intervals The PVPM automatically measures the I-V-characteristic of the generator at a capacitive load. From the measured data it calculates the effective solar cell characteristic, Ppk and Rs. [2], [3]. The I-V-characteristic can be shown directly on the bright TFT display. After the measurement the data are stored automatically in a nonvolatile storage and so they are available also later (in the office) [4]. The device can store the data of several thousand measurements.
