Hello,
Well, I'll give a stab at it. I havn't actually done anything
like this but it sounds pretty simple. Off the top of my head I
would think you could take your 12V battery run it through a 5V
converter and tie the 5V and ground to the same terminal connections
as where your solar pannel connects up. I think I would also add a
diode to each line going to the solar panels, not sure on that but
seems like a good idea just in case the battery tries to overpower
the solar cells. Like I said, not sure on this idea but is sounds
good in my head.
Good luck
Michael

Hello everybody.
I recently put together a small solar powered project. It draws
about
300ma at a regulated 5v. It runs great here in LA, but now I want
to
bring it to London. Obviously I'm going to be getting a lot less
power out of my panel. What I want to do now is attach a 12v lead
acid battery that can power the project when the sun is behind the
clouds (hopefully not all the time!). Is it complicated to power a
circuit and charge the battery at the same time? Should I try and
find an off the shelf solution to this problem, or is this
something
I can put together myself (with some help from the list)?
Any advice greatly appreciated.
