Circuit For Solar Battery Charger

Following my question 'Can a lead acid battery be charged and discharged at the same time ?', answer being yes, how is the battery,motor and panel connection like ? I am building a solar tracker and the battery output powers a motor.

The charger and battery are connected in parallel, which means that the load draws power from both and any "unused" power would be used to charge the battery. This is exactly how the electrical equipment in a normal car works as well.

after some trial and error, the latest revision is almost completely weatherproof, compact, and can power small appliances. the panel comes from ...

I already have a flexible solar array that can hang from my backpack. I am looking for control circuits that can effectively charge a p&s digital battery.

My array is 1x2' and puts out 12 volts and up to 400 milliamps at full...

I would go with a generator, charge your batteries during the day and light your path after dark: http://www.peterwhitecycles.com/schmidt. asp

I will be in the back country so I won't have access to electricity.

This website has a good circuit to do what you're looking for, although it needs a 6 V supply. I'd suggest either rewiring your solar panel so that it outputs 6 V (half the elements in parallel with the other half?) or continue to use the...

I am thinking of installing a solar trickle charger in my car. Most of them have a cigarette lighter plug-in for easy installation.

But I am not sure they will actually charge the battery. I cannot get power to the cigarette...

If your cigarette lighter works when the key if off, then yes, the solar charger will work. That will confirm you have popwer to the lighter when the key is off, thus the necessary connection to the battery.

I'm looking for an affordable way to charge a large 12v battery with solar power, but with a float so I don't boil it over and ruin the battery or worse. A year ago my brother and I nearly burned his house down with a tiny 0.5 watt solar charger that

Try, bass pro shops, cabelas, dicks sporting goods.
all the outdoor sports shops.
they run about 30 dollars for a marine one. Mine works very well.
Good luck man.

I am about to make a electronic circuit where i need am drawing power from 1 9 battery.. To charge that i have placed 2 9V solar cells connected to a lm317 so i will only charge them at 10% of their capacity. What will happen if i charge the...

Depends on the battery I suppose. All batteries have a limited lifetime (even capacitors). Does this circuit work 24hours a day? If so deign the circuit so that the draw from the batteries occurs at night and during the day you increase the duty of
