Innovative peak power and I-V-curve measurement device (curve tracer) for photovoltaic modules und strings up to 1000V and 20Adc The devices series PVPM provide the measurement of the I-V-curve of photovoltaic modules as well as strings. By a patented procedure the device can measure and calculate the peak power Ppk, the Rs and Rp from a single I-V-curve directly at the place of assembly of the PV system. Calculation results and the diagram can be displayed on the internal graphical LC display. The input of detailed module parameters is not required in common. The PVPM1000X is a mobile measuring device with integrated battery supply and external battery charger in a durable and watertight plastic housing. The device has its own industrial miniature PC and a high-contrast LCD TFT display and thus its function is independent of other devices. However if desired a PC can be attached for data transfer and further analysis of the measured values over a standard USB interface. The PVPM is operated comfortably over the touch function of the display and an on-screen menu. The functions are defined self-describing and the user is always led by the program. So no long training activities for the operating staff are necessary.
