The ones I have seen in the past were low current draw with an operating voltage in the ttl level range (at or near 5 v).    It takes a lot of discharge to bring a 12 volt battery with anything more than minimal a plate area from 12.52 volts (minimum voltage for a battery at "idle" before needing re-charge) to below 5 volts.  The 12.52V figure will be challenged, and likely isn't pertinent today; merely given as the benchmark that Johnson Controls and Sears Automotive Training used in their presentations about lead-acid batteries of the early 1980s.   I'm not saying that it isn't possible for someone to find a way not to get it to work...  Murphy is a Full-Time employee and is ACLU Compliant - Never discriminates.   A few weeks of very cloudy weather, inefficient solar panel(s), bad cell(s) in the battery, etc. could deeply discharge a battery.  anything is possible.   There are no free lunches, and there is no 1 to 1 mechanical advantage.  However, if your repeater eats light, and Mother Nature cooperates, this design is reported to work.    FWIW,   David KD4NUE     -----Original Message----- From: Repeater-Builder@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Dick Sent: Monday, February 20, 2006 3:25 AM To: Repeater-Builder@yahoogroups.com Subject: Re: [Repeater-Builder] Solar-Wind Powered Repeaters This gadget is gonna charge the batteries, then use power from the batteries to run itself?   Sorry, folks, but all my electrical engineering background says no way.   There's no free lunch.   Dick     ----- Original Message ----- From: Dakota Summerhawk To: Repeater-Builder@yahoogroups.com Sent: 19 February, 2006 22:32 Subject: RE: [Repeater-Builder] Solar-Wind Powered Repeaters Found this while browsing for generators: http://www.lutec.com.au/index.htm Might be a good idea for remote repeaters other than wind or solar.
