Peak power measurement device and IV-curve tracer for PV modules / strings / arrays, up to 1500V and 20ADC This PVPM device allows the measurement of the IV characteristic of photovoltaic modules as well as strings and arrays up to 1500V and 20ADC. Using patented methods, the instrument can calculate the peak power, the Rs and the Rp from one measured characteristic directly at the installation site and display the values on the built-in graphic display. The PVPM1500X is a portable instrument in a rugged and waterproof plastic housing with built-in battery power and external wide range battery charger. The device is equipped with its own high-performance miniature industrial PC and a high-contrast, high-resolution TFT graphic display and thus can be used independently. If required, however, a PC can be connected for data transfer and further analysis of the measured values ​​via a standard USB interface. The supplied calibrated irradiation reference sensor can be simply clamped e.g. to the module frame (parallel to the solar module). The IV curve measurement runs very fast (in the millisecond range), the measurement results (for example peak power) are immediately displayed on the built-in TFT display and stored permanently inside the device. Up to 4 curve measurements per minute are provided. Entering module data is not required for the measurement, but is supported both on-site at the meter and before the measurement campaign in the office. Additionally these informations can be added during evaluation in the office later on.
