Types of 12 Volt Solar Chargers

When it comes to saving money and reducing pollution and reliance on foreign oil, 12 volt solar battery chargers are a surprisingly simple and versatile choice. If you’d like to learn more about different types of solar battery chargers, please read on.

Generally speaking, a battery charger is a power supply that transfers electricity of a specific voltage to a battery. The battery placed in the charger, and disconnected after it’s completely charged. A 12 volt battery may be charged in a 15-18 volt power supply. However, this kind of battery charger poses the risk of overcharging.

When overcharged, a battery’s life is likely to decrease. A badly overcharged 12 volt battery may even lose its ability to hold a charge. Luckily, you can use a charge controller to ensure that the necessary voltage is used to charge the battery and that the battery is not overcharged. A charge controller will allow you to take advantage of the functions of a 12 volt solar charger without the danger of overcharging.

The most common kind of charge controller for 12 volt batteries is a Pulse Width Modulation (PWM) charge controller. In simple terms, a PWM charge controller works by flipping a switch on and off rapidly. The switch is mostly in the “on” position at first. As power is transferred to the battery, the amount of time the switch spends in the “off” position increases, and once the battery is completely charged, it no longer turns back on. A microprocessor chip oversees the charging process. Since it only transfers electricity to the battery when energy is needed, this type of charge controller can be left plugged into a battery indefinitely. Topping up a battery in this way is called “trickle charging,” and it will allow you to ensure that a battery is completely charged for whenever you happen to need it. If you’re using a 12 volt solar charger, it’s useful to have this type of feature. This, in turn, will allow you to keep the 12 volt battery for your boat or RV charged at all times.

With these basic parts, you can build a 12 volt solar charger. What differentiates a 12 volt solar charger from a standard battery charger is the power source. Solar battery chargers collect power through the use of a solar panel rather than through a wall outlet. If you want to save money, building a DIY solar panel to use in a 12 volt solar charger is a great way to go. Read more at DIY Solar Panel.

1/2 volt and 3-4 amp solar cells are commonly used in the solar panels that you might see on houses. If you’re using this type of cell, you’ll need to connect a number of them to produce the 15-18 volts necessary to charge a 12 volt battery. Currently, there are small solar panels of numerous different voltages available. The charger won’t work unless you match the voltage of the solar panel to your charge controller. The voltage rating on the charge controller indicates what voltage you’ll need. If you’re not using a charge controller, it’s best to use a solar panel of 15-18 volts. However, if you are using a charge controller, it’s necessary to use the appropriate voltage. You can build your own 12 volt solar charger with the help of GreenDIYEnergy.

Depending on the controller, the best way to wire it to the solar panel can be different. In most cases, it’s safe to solder the same type of connector onto the solar panel that you have on your charge controller. If you’re not using a charge controller, you can do so with the same type of connector that’s on the battery. Spring loaded clamps are a good choice if you’re using a larger type of 12 volt battery. Even if you’ve never done soldering before, this procedure would actually be a good place to start, as it’s a very simple one. A soldering iron and solder, which you can find at lots of places including Radio Shack, are all you’ll need to do this. All you have to do is twist the wires on either side together, applly the soldering iron to the wires, and touch the solder to the wires until it melts. You just need to be sure not to burn yourself, and to apply heat directly to the wires, not the solder, with the soldering iron – the solder is then melted by the heated wires.

It’s really as easy as that! Building a 12 volt solar charger is a quick procedure too. The first thing you’ll need is a 12 volt battery. A charge controller with the appropriate voltage is also required. Buy or build a solar panel that has the right voltage for the charge controller. The last step is to connect all the parts – connect the solar panel to the charge controller, and the charge controller to the battery. Once you’ve done this, you’ll have permanent, free power! This will cut your energy costs, reduce your emissions, and let you do your part in ending dependence on foreign oil.
