sorry for the lack of detail...
let me try again:
the solar panel is rated at 16.5 volts, 0.3 amps.
the charge controller is a black box- it is epoxied so you cant get at anything, or reconfigure it in any way. all it has is two ins for the panel and two out (rated at 12volts) for the batteries. model: morningstar sunguard solar controller, rated 4.5A 12V (SG-4 is written on the bottom inside)
the batteries are AA, 8 of them. as they were, were in one of those simple black holders, where all the batteries snap in and at one end you have two metal tabs, hot and ground.
I'm sorry if there isn't too much detail, but that's all there is... any reconfiguring of the controller will have to happen outside of the controller, as it is impossible to change it itself.
with that in mind, any advice?
