Types of 12 Volt Solar Chargers
Many people know that solar chargers are a good alternative to non-renewable energy sources, but not everyone has found out how easy they are to build. Read on to find out more about different types of solar battery chargers, including how to build your own.
The simplest type of battery charger functions by simply supplying a battery with electricity of the necessary voltage. All you need to do is connect the battery to the power supply, wait for it to charge completely, and then take it out. If you need to charge a 12 volt battery, you can plug it into a 15-18 volt charger. Unfortunately, this type of battery charger poses the risk of overcharging.
If you overcharge a battery, it’s probable that the battery’s functionality will be adversely affected, sometimes significantly. A seriously overcharged 12 volt battery can even lose its ability to hold a charge. However, you can use a charge controller, which will ensure that the correct voltage is used and keep the battery from being overcharged. A charge controller will allow you to take advantage of the functions of a 12 volt solar charger without having to worry about overcharging.
For 12 volt batteries, the Pulse Width Modulation (PWM) type of charge controller is the most common one. A PWM charge controller functions by, in a sense, flipping a switch on and off very quickly. The switch spends more time in the “on” position at the start. As electricity is transferred to the battery, the amount of time the switch spends deactivated increases, until the battery is fully charged, at which point the switch will remain off permanently. The charging process is controlled and monitored by a microprocessor chip. There is no danger of overcharging with a PWM charge controller, even if you leave it connected to a battery indefinitely. Topping up a battery in this way is known as “trickle charging,” and it will allow you to ensure that a battery is completely charged for whenever you happen to need it. This feature is obviously very handy for a 12 volt solar charger. 12 volt batteries for recreational vehicles and boats are often charged in this way, for example.
A 12 volt solar charger is just that simple. The source of the energy itself is the only thing that makes a 12 volt solar charger different. Of course, a solar panel provides the power for a solar battery charger. Many people are now building their own DIY solar panels. You can get more info by checking out DIY Solar Panel.
For the typical solar panels used on houses, the solar cells are generally around half a volt and three to four amps. Since a 12 volt battery charger needs about 15-18 volts of electricity to use, you’ll need to connect several of these cells to produce sufficient power. It’s possible to find small solar panels in many different voltages. The charger will work properly when you match the voltage of the solar panel to your charge controller. On each charge controller, you’ll see a voltage rating, which tells you the correct voltage. If you aren’t using a charge controller, it’s best to use a solar panel of 15-18 volts. Just remember to use the appropriate voltage if you are using a charge controller. You can build your own 12 volt solar charger with the help of GreenDIYEnergy.

Depending on the controller, the method for wiring it to the solar panel can be different. Usually, it’s possible to solder the same kind 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 safe bet if you’re working with a larger type of 12 volt battery. Even if you’ve never soldered before, this procedure would actually be a good place to start, as it’s a very easy 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 careful not to burn yourself, and to apply heat directly to the wires, not the solder, with the soldering iron – you use the heated wires to melt the solder. Another guide to building your own 12v solar charger that I recommend is Homemade Energy. If you’re interested, check out Homemade Energy.
It’s really that simple! Then, you can build a 12 volt solar charger. A 12 volt battery is the first thing you’ll need. Paying attention to the matching voltage, you’ll also need a charge controller. The solar panel, which you can build yourself or buy, should also output the same voltage. Finally, connect the solar panel to the charge controller, and the charge controller to the battery. That’s it; now, you’ve got free power forever! By using solar energy instead of oil to charge your battery, you’re helping cut pollution and dependence on foreign oil, and saving yourself a lot of money in the long run.
Where can I get an adapter/charger/power cord for a Hitachi DZ-HS500A?
I know it will not take a generic charger because it has to go through an adapter. Any suggestions on where to find one?
