Esmaeel Alshikh Feb 4 5 min read types of batteries which are used in alternative energy system Tubular liquid batteries. Tubular GEL batteries. Automotive batteries. AGM batteries. Lithium batteries. In the light of the excessive consumption of non-renewable energy resources, and the emergence of renewable energies on the scene, batteries have become the best economic and environmental solution to invest these resources and store their energy, whereas providing energy through batteries is an excellent way to keep on a clean and pollution-free environment. It also provides a lot financially, as it enables you to getting rid of large expenses for electricity bills. But before you choose the right battery for your home or workplace, you have to check the availability of some specification in it, such as its type and date of manufacture, which is very important because what happens inside the battery is a chemical reaction, and it also gives an idea of the battery storage time, which plays a negative role in influencing its performance, And the characteristics differ from one type to another, such as the difference in weight, the number of cycles and the dimensions of the battery, so try to take all the elements into consideration before you determine the type of your battery, and here is an introduction to the most famous types of batteries. Tubular liquid batteries: This type was specifically designed to meet the needs of electrical devices that require relatively low power for long periods, unlike similar liquid car batteries designed to give a relatively high rate for short periods that do not exceeding several minutes, in order to suit this purpose, the lead plates inside the tubular batteries have a wide area and less thickness. Tubular liquid battery characteristics: 1- Tubular batteries are ideal for solar inverters because these inverters contain a charging and discharging system for tubular batteries. 2- It is better equipped, which guarantees greater service and a longer guarantee for services that require energy for long and continuous hours. 3- Equipped with indicators to facilitate the process of monitoring the level of the liquid in it, and thus facilitating the maintenance process. 4- They last longer than normal batteries, and usually come with a longer warranty. Tubular GEL batteries: The gel battery contains lead immersed in a liquid from the inside, which has been converted into a gel-like substance to make the gel battery less fluid and more cohesive. A moist substance called a gel because it contains silica, and when acid is mixed with silica inside the battery, it produces a wet substance called gel. Advantages of Tubular Gel Battery: 1-This type of battery is characterized by the depth of charging and discharging, which makes it highly efficient. 2- It operates under high temperature conditions, and its life span is longer compared to acid batteries. 3- The possibility of placing it in any position, Since there is no risk of the gel spilling as it is a gel substance. 4- Designed for slow discharge for long periods of time. Automotive batteries: The car battery supplies the starting current to the starter, which requires a very high current that may reach hundreds of amperes within a short period. However, it is important to pay attention to choosing the appropriate battery size for the needs of the car and recommended by the car manufacturer, especially in modern cars, where the role of the battery is not limited to starting, but also supplies power to other electrical and electronic components for the purposes of monitoring and controlling the car and even for entertainment purposes. Advantages of car batteries: 1- It provides a continuous high density current for a relatively long period. 2- Easy to charge, it is charged automatically by taking advantage of the rotational movement of the engine while the car is working. 3- Continuity for long hours, so you can supply the electric components of the car with current even if they are not in charging mode. AGM batteries : It is an abbreviation that means absorbent glass network batteries, as they contain a fiberglass network that absorbs liquid and keeps it from movement, vibration and even sedimentation if the battery is stable for long periods. A safety feature of this type of battery. Among its most important characteristics: 1- High capacity for charging and storage 2- It is a closed battery, Because of the glass mesh that limits the movement of the liquid, it bears concussion, and even can be used in unfamiliar positions, such as being placed on its side or upside down. 3- It does not require maintenance, and it is manufactured under environmentally friendly conditions and is suitable for home use. Lithium batteries: The most important thing that distinguishes it is its ability to discharge almost all of its energy, while the rest of the batteries may be exposed to the risk of damage if their energy is completely exhausted, and it enjoys a stable voltage on its two ends for a long time despite its low charge, which makes it suitable for sensitive applications for effort. However, Its small size and light weight make it the most suitable choice to meet daily needs and provide energy for devices with simple consumption. The most important features of lithium battery: 1- Fast charging in a short time, thanks to its ability to withstand high charging currents. 2- Provides energy for long periods and lasts long without the need for charging because of the very low self-discharge current. 3- Never need maintenance. 4- It provides high and stable current. In conclusion; to avoid mistakes while choosing a battery, specify your requirements accurately and search for the type of battery that may suit your requirements and check the availability of quality specifications in the battery before purchasing it, try to check the type of battery to be suitable for your use, it may be liquid, dry, gel, or Lithium. Do not forget to ask about the type of the guarantee and its duration. 0 views
Common mistakes when installing a solar energy system
Esmaeel Alshikh Feb 4 5 min read Common mistakes when installing a solar energy system There is no doubt that solar energy is one of the most important topics globally, so we must rely on clean energy because it is the main factor in preserving the climate, and it is the key to reducing global warming and avoiding the effects of climate change. Solar energy applications have varied to include household, agricultural and industrial aspects, until it has entered almost every home, so it is important to go towards clean sources of energy in addition to being one of the most important investment fields. The use of solar energy is increasing rapidly and there is an increase in demand for it because it is continuous and renewable energy that is interminable and has a great economic return. It reduces the value of monthly bills and is characterized by its various uses. Therefore, during the installation of the solar energy system, some points and tips should be taken into account. The most common mistakes during the installation of the solar energy system: First – Errors related to the installation of solar panels: 1- Not taking into account the shade when installing solar panels: – The angle and location of position of the solar panels play an important role on their efficiency, so you must leave a distance or raise the base of the panels to make distance between the shaded body and the panels.The natural factors can also affect the capacity of the panels, where the shade is due to environmental obstacles such as clouds and self-shading between panels in parallel rows and dirt such as dust and other. To avoid this problem, you should pay attention to the site before installing solar panels and make a careful analysis by studying the site throughout the day. You also need to study the surrounding sites if there is a nearby building under construction or a shade of a tree. 2- Inappropriate angle and direction of the solar panel: The direction of the sun rays on the panels plays an important role in the speed of charging the batteries, and therefore it is important to pay attention to placing the solar panels in a location that allows them to be exposed to the largest possible amount of sunlight. Therefore, the maximum angle for polarizing solar light must be taken into account during the installation of the panels. For example, if we take the Middle East region, the solar panel must be placed at an angle of 30 degrees normally in the summer and it changes slightly in the winter, but it remains 30 on average. The angle of inclination of the solar panel must be placed towards the south with inclination towards sunset, but it may vary according to the country and the season. 3- Poor implementation of installing panel fixing structures: Installing solar panel bases made of light iron that is subject to oxidation and rust leads to an inevitable disaster and the panels will fall and break and it may lead to human damage. The bases must be solid, strong and resistant to weather factors such as (rain, wind, moisture, heat…) and the best is always Use bases made of aluminum alloys or galvanized iron to keep them sturdy and cohesive (especially in high humidity areas). Second – Using automotive batteries instead of solar energy batteries: – We also note the widespread use of car batteries instead of batteries designated for solar energy, due to the users’ lack of awareness of the basic differences between the two types. However, the difference is very large. The car battery is designed to give a large current only at the start of the car’s engine, and it is called the takeoff current, while the solar battery is designed for charging and discharging continuously. Therefore, we recommend using one of the following types of batteries: 1- lead acid tubular batteries: They last longer than regular dry batteries, and usually come with a longer warranty. 2- Gel tubular batteries: They work under high or low temperature conditions, and their life span is longer compared to lead acid batteries. 3- Lithium battery: It has a longer life cycle, greater energy storage and fast charging. We also recommend using distilled water for batteries instead of tap water, because it negatively affects the performance of the battery, because it contains minerals, which in turn interact with the acid in the battery, reducing its concentration. On the other hand, these particles are precipitated on the cells and reduce the interaction between the cells and the acid in the battery. Therefore, we recommend using distilled water, as the warranty is voided when using ordinary water. Third – placing the inverter in an open place or exposed to weather factors and sun. Some users place the inverter in a place exposed to heat, sun, humidity and rain, and this is a wrong behavior unless the device is designed to work in the open air. The inverter must be generally placed in a place with good ventilation because the inverter contains cooling fans and the fans are placed at the bottom of the inverter or on its sides, which in turn brings out the hot air from inside the inverter when its temperature rises, so it is necessary to leave a certain distance between the inverter and the wall to maintain the mechanism of the inverter fans working properly, which in turn regulates the work of the inverter and maintains its temperature regulation. Previously, we find that there are many errors that we may encounter when purchasing and installing a solar energy system, but it is possible to avoid them by taking the previous tips and advices into consideration, and it is preferable to deal with companies that have the appropriate experience, including engineers and technicians with high experience in installing the solar energy system. 0 views 0 comments 2 ❤️
