Maintaining a Solar Power System using GENNECT Cross

Maintaining a Solar Power System using GENNECT Cross
 

Photovoltaic (PV) systems are built to last and are meant to be both sustainable and efficient. Regular inspections ensure that they are operating efficiently, producing the cleanest energy possible, and preventing unnecessary and costly problems in the future.  PV systems require extensive measurement hours in the field followed by long hours creating reports in the office because they have various measurement locations and parameters. You can use GENNECT Cross, a free application that connects compatible Hioki instruments to mobile devices via Bluetooth communications, to save time and improve quality. Challenges Due to the large number of measurement locations, you can’t write down all the measured values. Creating reports is extremely time-consuming. Caution is necessary from a safety standpoint since you’re measuring high DC voltages. Solved by GENNECT Cross! Since all measured values are transferred by Bluetooth®, there’s no need to write anything down. You can create reports while making measurements. You can ensure safety by using a voltage probe that can accommodate up to 2000 V. Measurement parameters The circuit breaker for every string in the junction box must be measured. With 300 strings per megawatt, a large power plant can have thousands of measurement locations.
