This video is for new Elon 100 units from September 2019 onwards. See this page for a user instruction video for the old Elon 100 up to August 2019.
(How do I know if I have an old or new Elon 100? The controller for the old version says “Efficiency” below the dial (knob), whilst the controller for the new version has “Turn anticlockwise to increase solar hours” below the dial.)
