Unfortunately during the test the DFRobot DRI0017 failed, probably because, when I connected the battery (so without any over-current protection), the peak current exceeded the maximum current the L298 was rated for.
Ordering a new part will take at least 5 days. I made some videos of the preliminary tests and I am going to publish these video as a proof of the work done during this challenge. I am very sorry I can't test Rullit on real PV modules, but I will update about progress as soon as I will be back on track
