With the device PMD5000 from Tele Haase, photovoltaic plants can be checked for module errors within a few minutes – without the need for maintenance personnel climbing on the roof. The new device developed with the support of FH Campus Vienna, operates according to the principle of a characteristic form check. In contrast to conventional, sensor-based measuring methods, it enables a quality check during the start-up of a system as well as during operation, without the hassle of attaching sensors.
This greatly facilitates the work of electricians and solar technology specialists. They can now effortlessly create a test report and accurately document the condition of a system for their customers. In addition to the pure testing of the PV system, the PMD5000 also offers an interesting potential for longer-term maintenance contracts. With the new device, it is possible to subject the PV system from the ground or inverter to a comprehensive test in the space of a few minutes. For this, the strands are simply marked and measured at the inverter. In the case of firmly clamped strands, they can also be measured in parallel. The installer or solar power specialist will receive a characteristic curve at a glance, which provides information on the condition of the system. In this way, as a proven, reputable provider, they can easily record even during the set-up that everything is correct and document the quality of their work.
