What happens if I supply 18V to a 12V lighted switch?
At the moment I only have the arming switch wired up. It is running off of 2 9v batteries, making the total voltage 18v. Note I have little technical/book experience as far as understanding electrical work (I.E. do''s and don''ts, I don''t know the do''s and don''ts so.
What''s the difference between 12V and 18V panels?
Also, most panels advertised as 24V are really 36V or two 18V panels in series with an open-circuit voltage well above 40V. Both 12V and 18V panels are listed for sale on Amazon and inspection of the electrical specs shows that they are essentially identical. Share Share. Reading next. Start Your Journey to Sustainability.
