Mini zestaw PV- moje błędy,lepiej się wpiąć pod wyjście akumulatora ? Obliczam straty dla przewodów🤔

In this video, I examine whether wire gauge really matters in photovoltaic installations and how it affects charging efficiency. I test various wires on a PV panel, demonstrate my own connection solutions, and demonstrate how I connected the smallest battery to the system. I also explain why it's better to connect a QC (Quick Charge) board directly to the battery instead of to the controller's output—this ensures stable and uninterrupted charging for your phone, regardless of the MPPT controller's operation. If you're interested in DIY photovoltaics, experiments, practical tips, and equipment testing, this video is for you.
