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.)
