12 Volt Charge Controller

No - the controller would try to overcharge the battery, exactly what the controller is meant to avoid. You could charge two 12 volt batteries in series though.

A Solar Charge Regulator aka Controller acts as voltage regulator allowing batteries to charge without overcharging. 7 amp hours at 12 volt = 12 ...

I am building my own wind turbine and would like to build a 12 volt charge controller. Looking for any help thanks in advance.

here i hope this site help you..and also they have mini course on how to build your own wind turbine..

go green!!

If you wanted to replace the tire on your car, you might design a tire manufacturing company and build a replacement. Or, you might buy a good replacement, possibly used.

If you want to safely charge a battery, you might design a ....

I have four 12 volt batteries connected in series, and two 80 watt solar panels with a 12/24 volt 30 amp controller. What would be the most effective connections to charge the batteries?

Read the manual for your controller, which I assume is a charge controller. The better ones use a switch mode regulator so they operate over a wide range of input voltages and output voltages.

The manual should tell you what range...

I'm building a solar panel, well i have built it and now im hooking it up to a 12V car battery to see if it is working ok. I have a 20 amp 12 V charge controller, i used a multimeter to check the volts coming from the solar panel when in the sun...

It is not good for the battery to be disconnected from the controller while the panels are putting out power to the controller. It is recommend not to do it.

Hooking an ac to dc converter into the wires to the battery can cause damage

I live in a village in Africa as a humanitarian aid worker. My only source of power is a 30 volt solar panel. I have it wired into a 3 stage controller and from there into a 12v/150ah car battery. Everything is wired correctly and working....

use your lead acid battery as the main charger
1 battery gives you 12v
2 batteries gives you 24v ( connect the battery in series of course)
now how to make the voltage drop to suit your required voltage? use high wattage...
