Solar charge controller
With so many advantages and its usefulness you may have decided to purchase a solar unit for powering your appliances. The solar panels are capable of charging the batteries even when there is insufficient light which makes it possible for the electrical appliances to function irrespective of the amount of light that your solar panels is absorbing. However, you need to be careful about certain things when you make your choice of solar power system. Though every component of the solar unit is equally important for its efficient functioning, you need to be particularly careful with the solar charge controller. The responsibility of the solar charge controller is to protect your battery. The batteries are known to have less storage space and the sun produces energy as long as it shines which may overcharge your batteries. You need to be sure that the solar charge controller matches your battery's voltage. You will be informed regarding the amounts of watts that will be produced on the kit that you purchase. You have to determine the amount of watts that you need daily and then purchase the suitable kit.
The quality of your solar charge controller affects the lifespan of your batteries. When the battery has a charge deficit the lead plates which are inside the battery corrodes and this process of corrosion produces electricity. When you recharge your batteries, your plates are also rebuilt which supplies ample charge.
If there is appropriate charge in the right amounts at right intervals the terminal plates inside the battery will be restored to their previous situation that takes place through metal crystals which grow on the plate's surface. In case the metal crystals do not grow at its best rate to produce large crystals, the metal will fall off the plate in chunks and start accumulating at the battery's base. This causes the batteries to degenerate.
You need to buy the best quality solar charge controller to increase your battery's life. A cheap solar charge controller will result in short life of the battery and you will have to incur expenses by replacing your batteries regularly. Most of the solar kits have easy installation methods and if you follow the instructions step by step you will not face any challenges.
The technology that is used in the solar charge controller is the PWM. Using this technology ensures that you battery is charged fully, slows the PWM pulses generally reducing off the charge. It is necessary to have pulsing for your batteries as it combines very gently with the electrolyte and avoids forming of layers.
The low voltage used for disconnecting prevents the batteries from discharging severely as it shuts off the load before the voltage of the battery reduces to dangerous levels which could damage the unit. The set point voltage is adjusted to match with the surrounding temperature.
The solar charge controller consists of many mechanisms such as a potentiometer which is used for adjusting the voltage that floats. Most of the solar charge controllers contain an equalize function that is helpful during situations when overcharging takes place and immediately a regulatory function is put into action which provides the best battery charge in accordance with the temperature automatically.
The most vital component in the solar unit is the storage system where the generated energy is stored for later use. For the storage system batteries made of either lead acid or cadmium are used. These batteries can either get overcharged or become drained and that is why the solar charge controllers are used to prevent this situation. Once the batteries are fully charged the controllers stops the battery from getting further charged.
