A solar battery charger is just any device which use solar power to instantly fill a discharged battery pack with fresh solar energy and then is used to recharge the battery. They may be small (such as portable phone chargers) or very large (such as those used for boats and RVs). They come in several designs and are designed to charge specific batteries, whether car, boat or RV. There are many types of these devices, and they differ from one another both in how they work and the amount of power they can produce.
There are basically two different types of solar battery chargers. One type works by allowing charged particles from the sun to flow through an interface, which is basically a piece of glass. This glass faces either north or south, depending on where the sun is positioned. These devices generally have two ports: one for the solar charger and the other for connecting to the battery. The only way to remove the power from the battery is to completely dead battery it, which takes about four hours.
These devices, such as the portable ones mentioned above, are made from flexible polyethylene, commonly called pinhole. These are flexible, easy to install, and can handle a wide range of voltages and sizes. On the other hand, there are rigid solar battery chargers that use stainless steel connectors. These are often used with off the shelf devices such as cell phones, laptops and mp3 players. These are often referred to as “green connectors” since they use a minimal amount of copper wire to complete the connection.
The main function of a solar battery charger, then, is to change the current produced by the device from direct current (DC) into alternating current (AC). The most common type of solar cell that works in this manner is a photovoltaic cell. These cells convert light energy into DC current, which is then used to power the electrical device. The process works the opposite way when charging: instead of allowing positive or negative charges to build up in the cells, the incoming DC current is allowed to run through a series of small conductors, causing the electrons in the cells to be separated from the overall electric field.
Most solar battery chargers, therefore, operate using a standard DC input. There are, however, a few devices which require an additional 12 volt input, such as the laptop charger mentioned earlier. In this case, the solar charger needs to be connected to a negative battery port. The most common 12 volt battery chargers that utilize a DC input are those designed to power smaller items like cell phones, laptops, handheld GPS devices, and similar small electrical devices. These smaller devices have their own power supply circuitry, which allows them to operate even when the unit’s power source is down.
The problem with DC based batteries is that they cannot operate efficiently under the effects of direct sunlight. Direct sunlight will gradually drain the charge of these batteries to almost nothing, eventually reducing their overall usable life over time. In order to avoid this problem, most chargers use what is called a trickle charge, wherein a small amount of charge is obtained per day while the unit is in operation, and then it is gradually drained when no direct sunlight is present. This allows for continuous, regular use even on extremely hot days.
There are also two main types of solar chargers: the trickle chargers that use a DC input, and the direct-conversion chargers. The first type uses a bank of batteries filled with electricity, while the second type converts the DC input of the array into AC electricity. These chargers can actually operate on either type of power source, although using the same batteries. Many modern cars now use some form of solar battery charger, as this type of technology is quickly becoming more widely available. This allows people to run their cars indefinitely on stored electricity produced by the sun.
The cost of these solar chargers varies significantly, depending on the brand and quality of the unit. It’s always a good idea to shop around in order to find the most reasonable prices. Most reputable manufacturers of these devices can be found online. Low prices can often be obtained by shopping around and looking for discounts, manufacturers promoting sales, or by buying multiple units at the same time.
Noco batteries are among the most widely used and recommended brands, so it is not hard to find a product that will work with most solar devices. Noco also makes products that combine numerous different types of batteries into one single, easy to use package, which makes converting a variety of different devices much easier.
