US startup offers AI-based software solution to predict component failure in utility-scale inverters
Infinrel says its Energy Kardio Graph solution can sample small electrical perturbations on the input and output of the inverter at MHz scale and enable insight into the actual operation of the inverter on its switching cycle basis.
Dutch hackers report flaws in Enphase IQ Gateway devices
Two “ethical” hackers from the Dutch Institute of Vulnerability Disclosure (DIVD) have identified six vulnerabilities in Enphase IQ Gateway devices. The researchers are now working with the US inverter manufacturer to address the bugs in the next version of the product.
Low-cost machine learning framework for snail trail detection in PV panels
Conceived by French scientists, the novel system uses ensemble learning and does not require anything more than a commercially available optimizer. Before it makes a decision, the method combines K nearest neighbors, support vector machine, and decision tree learning. Accuracy is reportedly up to 89%.
New approach to measure PV inverter degradation in semi-arid climates
New research from Morocco has found that the Sandia PV Array Performance Model is the most suitable for measuring AC power in PV systems located in arid-climate conditions. The scientists conducted a series of tests a three different PV systems located at a testing facility in Ben Guerir, in central Morocco.
