12v Battery Charger Circuit From Solar Panel

Once we attach the charger with the battery voltage drops from the actual supply 14 2 v level to the discharged level of the battery.

12v battery charger circuit from solar panel. 20w 12v or 10w 6v output voltage range. 10w includes power dissipation of d1 typical dropout voltage. With the dimension of 13 4 9 8 0 7 inch and 2 4 lbs this charger is lightweight and portable. This low drop solar panel charger circuit is going to be used to accomplish optimum current from a solar panel system whilst charging a conventional lead acid 12 volt battery.

2 to 2 75v depending upon load current maximum current. Here is the simple circuit to charge 12v 1 3ah rechargeable lead acid battery from the solar panel. Flexzion solar charger controller 10a pwm solar panel battery regulator 12v 24v solar energy system smart overloading and short circuit safe protection 3 9 out of 5 stars 5 11 99 11. Of course it will put additional load on ups battery which is hardly fully charged due to frequent load shedding.

This circuit may also be used to charge any battery at constant voltage because output voltage is adjustable. You need to connect the ve terminal of one solar panel to a ve terminal of the other solar panel. 1 5a internally limits at about 2 2a. A 12volt solar panel typically contains 36 or 48 photovoltaic pv solar cells wired in series size 25 inches by 54 inches produced dc electricity.

5 to 14v adjustable may be reduced further by shorting r2 max power dissipation. Solar battery charger specifications. It gives you approximately the identical current as though the solar panel was attached straight to the battery. The solar panel is made from poly silicone that can produce up to 10 watts 556 ma and ocv 21 3 v.

It will charge the battery and will turn the lights on off. You can use readymade 12v 10 a bridge rectifier which is available in the market. This solar charger has current and voltage regulation and also has over voltage cut off facilities. Solar panel battery charger 100 watt 12v generate 13 6 volts to 17 0 volts dc electricity allows charging li ion or lead acid battery.

The other best solution is to install 12 volt solar panel and attach all these four smd lights with it. As the battery gets charged the terminal voltage begins increasing gradually until it reaches the set 14 2 v. It has 12v operating voltage. If you want to more high current then replace the transformer with 10a and use 10a10 diode.
