Solar Battery System Types – AC Vs DC-coupled

Published on: 13 October 2020 Last Updated on: 13 September 2024

Before you choose the right solar battery, you first need to learn what AC and DC coupling means. Your solar battery storage system determines how effective your solar air conditioning will be.

There are two main ways to connect your power sources when you add battery storage to your solar energy system. AC and DC are the two main types of voltages used to conduct electricity.

Let’s find out what differentiates these two battery systems.

What is the Difference Between AC and DC Power?

AC stands for Alternating Current, and it means electric power first flows in one direction and then the other. This is the type of electric current on the main grid, and it’s suitable for your solar air-con.

DC power, on the other hand, stands for Direct current, and it means electricity flows in one direction only. This is the electric power that your solar panels generate from sunlight. The energy stored in your home’s solar battery is usually DC power.

Since your solar panels generate DC power and your solar air conditioning and other home appliances need AC power, you need a solar inverter to convert this energy to AC electricity. There are three main types of solar inverters in the market;

Traditional Inverters

This first type of inverter is also known as the central inverter because it draws power from your solar panels. If you have a solar air conditioner at home, you’ll need this kind of converter to keep it running.

It is usually a box that’s installed next to your home’s breaker box. It functions by combining all DC energy from your solar panels and converting it to DC power so that you can use your solar air conditioner Malaysia.

Micro-Inverters

The second type of inverter is an in-built component on individual solar panels. They are small inverters found on the backside of your panels. They allow your panels to individually and independently convert the harnessed DC power to AC energy.

DC-Optimizers

Lastly, we have the DC-optimizers that are devices that also go at the back of individual solar panels. Unlike Micro-inverters, they don’t convert DC to AC. Instead, they optimize conditions to ensure your home’s central inverter has an easy time converting DC to AC power. These converters work in a hybrid solar energy system that includes a traditional central inverter and in-built solar panel inverters.

Is a Battery DC or AC?

Batteries, like solar panels, store and produce DC power. Since your home’s electricity is AC, it means batteries in devices have converters that turn the AC power to DC energy.

DC batteries use the same solar inverters that your home uses to convert the stored DC energy to AC power. AC batteries, on the other hand, have an in-built inverter that directly does the conversion.

AC Vs DC -Storage Architecture

Comparing the strengths and weaknesses of these two battery storage systems helps you choose what is best for your home.

DC-Coupled Systems

The DC-coupled system is designed to connect directly to the main grid the same way as your solar panels. In which case, a hybrid inverter is required to create a synergy between the solar battery and the solar panels.

Strengths

There is less energy loss because it’s a one-way conversion.
Your system makes you eligible for Net Energy Metering if your solar panels can generate excess energy.
It is a simple system which translates to lower costs.
It is a smart option for people who’re just beginning their solar energy journey.

Weaknesses

If you already have a PV system, incorporating it is complex and costly.

AC-Coupled Systems

The AC-coupled system operates with two solar inverters; a conventional inverter and an additional storage inverter that charges your solar battery. It might seem like a complicated system, but it is very easy to setup. However, as compared to the DC-coupled system, it’s less efficient because it has to be charged.

Strengths

It is way more flexible than the DC-coupled system. The inclusion of two inverters allows you to adjust the location of the battery at will.
It is compatible with all kinds of solar inverters.
It is a cost-effective solution for people that already have a PV system.

Weaknesses

The system is slightly less efficient as compared to the DC-coupled system because of the AC-DC-AC conversion.
The system will have more points of failure because you’ll have one inverter in a different location.

Which Is Better for your Solar and Storage Needs?

If you already have a solar energy system at home, you should go with the AC-coupled system because it’s flexible and easy to set up. However, if you’re just starting your solar journey, you should go with the DC-coupled system; if you generate excess energy, you get to sell it to the main grid.

Final Thoughts

Understanding the difference between these two solar battery systems helps you make the right purchase. Ensure that you work with a professional who understands what is best for your home. Solar energy systems are here to stay, and you might as well jump on the bandwagon because it’s a system that pays for itself.

What Is A Solar Park Like? Discover The Heart Of Solar Energy!

Hello to all the solar energy enthusiasts! Today, let's dive into the fascinating world of a solar park. If you've ever wondered what a solar park is like and what makes it work so efficiently, you're in the right place. Join us on this solar journey and discover the secrets behind a solar park, with a special focus on Soltec USA's solar tracking systems. What is a Solar Park? First, let's get some context. A solar park is a large-scale installation where solar panels are used to convert sunlight into electricity. These parks can vary in size, from small community projects to massive installations supplying energy to thousands of homes. But what makes a solar park so special and efficient? The answer lies in the combination of advanced technology and smart design. The Infrastructure of a Solar Park We need to know its main components to understand how a solar park works. Here are the key elements: 1. Solar Panels Solar panels are the heart of any solar park. These photovoltaic devices capture the sun's energy and convert it into electricity. In a typical solar park, thousands of panels are arranged in long rows, all oriented to maximize sunlight capture. 2. Inverters The electricity generated by solar panels is direct current (DC). For this electricity to be useful in our homes and businesses, it needs to be converted into alternating current (AC). This is where inverters come in. These devices transform DC electricity into AC, making it compatible with the power grid. 3. Solar Tracking Systems This is where the magic really happens. A solar tracking system allows the panels to follow the sun's movement throughout the day. Instead of remaining stationary, the panels move to maintain optimal orientation to the sun. This can significantly increase the amount of energy produced. Soltec USA is a leader in this technology, offering high-end solutions that maximize energy efficiency. 4. Transformers and Substations Once the electricity has been converted to AC, it needs to be transmitted to the power grid. Transformers step up the voltage of the electricity so it can travel long distances without significant losses. Substations manage the distribution of this electricity to different destinations. The Role of Soltec USA's Solar Tracking Systems Solar tracking systems are a vital part of an efficient solar park. Let's delve into how they work and why they are so important. A solar farm has unmatched functionality when it comes to creating sustainable energy resources. But, maintaining a solar farm is equally important in terms of utilizing it efficiency. One such matter of maintenance is having a solar tracking system for your farm. Here are some of the solar energy tracking functionality which can make running your solar farm even easier. There are three types of solar tracking: Manual Solar Tracking Manual solar checking is the most tedious one in a solar farm. This is when a person has to literally walk towards every solar panel, check the energy level, and then tilt the panel towards the sun from time to time. The solar panel cannot remain at a tilt towards the at all times, as this risks damage. Passive Solar Trackers Passive trackers consist of an internal mechanism consisting of a liquid reaching a boiling point. When one exposes the panel to the solar radiation, the liquid begins to boil. Hence, this is a sign that the saved solar energy is being utilized. During utilization, the liquid evaporates. Once there is no boiling liquid in it, then there is an imbalance in the solar panel. This automatically causes the panel to tilt towards the sun. Automatic Solar Trackers Automatic solar tractors have even higher mechanisms. They consist of electric motors, and hydraulic cylinders which change the position or tilt of the panels on their own. It is a fully automated process with very little human interruptions, which is again limited to cleaning & maintenance (when necessary). This form of automatic solar tractor can be divided into two parts: Single axis solar tracker: This tracks the movement of the sun from east to west, ensuring proper collection of the solar radiation. Double-axis solar tracker: They have two axes that tilt from east to west and north to south. This type of solar tracker is perfect for commercial solar farms that run completely on solar energy. Maximize Collection As a commercial solar farm, you should always opt for the automatic solar tracker, as it improves its collection efficiency. The position of solar radiation changes throughout the day. Mornings are when you get the highest solar radiation from the east. Then as sunset approaches, the strength increases towards the west. Therefore, a solar radiation only facing one side doesn’t guarantee maximum collection. This is why trackers play such a crucial role. Adaptability If your solar farm is on a higher altitude or a location with heavy clouds, a solar tracker’s adaptability is of great assistance. Thus, an automatic tracker can locate the spot where solar radiation is the highest and collect it efficiently. Gets More Sunlight The sun is up way before we are! Plus, we do not register the solar radiation at dawn and dusk to be strong enough to generate solar power. Turns out they are! Therefore, the tracker will help to efficiently get the most of the sunlight throughout the day. Advantages of Solar Parks If you are still contemplating whether you should install a solar farm for your personal and commercial purposes, then keep reading. We understand the matter of budget. Yes, installing an entire farm is a matter of high investment. However, understanding the advantages that you can utilize for years to come will definitely make it cost-effective. 1. Clean and Renewable Energy If sustainability is what you are striving towards, then look no further. Fortunately, with the help of modern technology, we are able to utilize a very important natural resource. With further improvements, we are now able to bring that to our everyday domestic usage. With solar-powered everything, you are using clean, renewable energy. This leads to less air pollution, a major decrease in your carbon footprint, and, overall, contributes to a better future. 2. Low Operating Costs Once a solar park is up and running, operating and maintenance costs are relatively low. For example, Soltec USA's tracking systems require minimal maintenance thanks to their robust and efficient design. 3. Job Creation The construction and operation of solar parks create jobs in various areas, from engineering and construction to maintenance and administration. 4. Energy Independence Solar parks can help communities become more energy-independent, reducing their reliance on energy imports and improving energy security. The Final Note! A solar park is a masterpiece of engineering and sustainability, combining solar panels, inverters, transformers, and advanced solar tracking systems. These components work together to efficiently and sustainably convert sunlight into clean, renewable electricity. Plus, we hope this article was able to provide you with a clear and fascinating insight into the functions o a solar park. Next time you see a solar installation, you'll know that behind those panels is a complex network of technology. Matched with design that is working tirelessly to harness every ray of sunlight.

What You Need To Know Before Installing A Greenhouse

If you decide to up your game in gardening by widening your space and growing more crops, plants, fruits, and veggies, it’s time to consider investing in a greenhouse. Nothing beats the convenience of harvesting organic ingredients and producing straight from your garden. Not only does this help you save money, but it also allows you to explore more variety of seedlings to grow. Greenhouses are an excellent environment for fruits and vegetables to grow in their best state. Because of the safe enclosure, insects and external conditions cannot adversely affect their growth and condition. This safe haven ensures your plants' nourishment to reap the best quality of produce later on. However, before installing a greenhouse, you should acquire more knowledge and learn helpful techniques. Here is everything you need to know before installing a greenhouse. Type Of Greenhouse Design In order to buy or build a greenhouse, you first need to figure out how much-growing space you will need and what type of greenhouse design is best for you. You will have to continue using the same greenhouse for many years, so choose a size that will provide ample space for all the crops you wish to grow and care for. Opt for a reliable greenhouse company that includes installation services. Purchasing With Installation Included Some greenhouse specialists like Swgreenhouses.co.uk will include installation with your purchase, which means you don't have to worry about installing it yourself in your own garden, which can save a lot of worries. Upon choosing the company or provider, don’t forget to seek advice on what type of greenhouse would best fit your needs and preferences. Here are two types to consider: Attached A lean-to or attached greenhouse offers the advantage of not having to build all four walls. It can significantly reduce greenhouse construction or installation cost. Since the foundation is already within your house, the greenhouse will remain stable and sturdy. Many home gardeners choose this greenhouse option because it’s easier to construct and cost-effective. The ideal area in your home to install an attached greenhouse is to find a place with enough sunlight. Freestanding The other option you can choose is freestanding greenhouses. It is the best bet if you want to place your greenhouse in different locations within your home. While they may require a heftier initial investment, you can see how cost-effective they can be in the long run since you can grow more plants in them. It also enhances your curb appeal as they become an extended sanctuary of your home. You can add decor or furniture and keep your greenhouse an additional space to entertain guests or spend time with the family. Because of their multiple purposes, freestanding greenhouses can be an excellent investment. Consider The Plants You Want To Grow Another important step before constructing or installing your greenhouse is deciding the kind of plants you’ll grow. This will help you determine the requirements for growing them and guide you in designing the greenhouse. If you don't know what kind of plants to grow in your greenhouse, you can't properly plan the proper temperature or lighting. To care for your plants and vegetables, you have to factor in their sunlight and water requirement, temperature, humidity, and other factors. Choose plants that are matched to how your greenhouse can supply these elements. Also, note that you'll need to buy greenhouse tools, equipment, and accessories based on your chosen plants. The good news is that you can grow any plant in your greenhouse. This is because the greenhouse's main benefit is that you can control all these necessary elements to keep your plants strong and healthy. But you will need to decide what types of species grow well together and keep your greenhouse successful and effective. Whether you’re thinking of growing spiky plants that can be used to decorate houses or fruits and veggies that can be grown organically, the key is to be familiar with several plant species and their corresponding care requirements. After all, you'll be able to plan which plants can grow together if you have a broad understanding of the plants you're growing. Choose Your Location Choosing your location is important when deciding to invest in a greenhouse. If your greenhouse is near your home, you can visit and monitor it more often. However, if it’s a bit far, you might not be able to care for it frequently. Make sure it’s strategically located somewhere you or your family can easily access. When choosing the best location, the general rule is to select a place where the sun shines much longer and more often. Thoroughly study and assess your residence, and see where the sun rises and sets daily. Consider these factors when deciding where to install your greenhouse. Find an area where your greenhouse will have protection against strong winds and frost pockets in case these instances occur. Light, Water, And Ventilation Finally, you have to ensure that your greenhouse will have convenient power sources, water, and air ventilation. This will enable you to install lighting and water fixtures easily. Your greenhouse must meet some requirements regardless of style, size, or construction method. Consider the aspects below: Electricity You can control temperature easier when you install fans within the greenhouse. Wire the outlets safely and securely, and acquire all permits when installing a greenhouse. Aside from using a commercial power supply, you can consider installing solar-powered panels to generate electricity for the lights necessary in the greenhouse. Air Ventilation Air ventilation can be increased through the use of indoor greenhouse fans. They help alleviate extreme temperatures and climates. Airflow prevents warm air from rising, whereas cold air gathers below near the plants without airflow. Install fans or roof vents to promote more ventilation. Water Your greenhouse must have water access. Many greenhouses use garden hoses that are attached to a nearby resource. However, you can also go for automated sprinkler systems, which can be scheduled or turned on manually without having to go through all plants one by one. Conclusion Your greenhouse investment will ultimately depend on you. You can do it yourself or hire professionals to install them successfully in your home. However, it’s crucial to know the details and aspects mentioned above to make your greenhouse construction project a breeze.

HVO Fuel Uncovered: The Secret Fuel That Could Change Everything

The "fight" for a cleaner planet has been going on for a long time. People are trying to beat themselves because they and the things they use are the main polluters. Cars and everything that uses fossil fuels are among them, considering their emissions of exhaust gases into the atmosphere are huge. At the global level, governments make efforts to reduce dependence on fossil fuels, knowing these are the biggest polluters. That's why the desire to find alternative sources of energy from renewable sources has been present for a long time. While there are already certain options in use, as you can read here, new solutions are constantly coming up with improved performance and lower CO2 emissions. Alternative fuels are essential for sustainable carbon-free energy supply and reduction of greenhouse gas emissions. And while you're probably already familiar with their use, HVO (which stands for Hydrotreated Vegetable Oil) might be new to you. This low-carbon liquid fuel has gained attention lately because it seems like the long-awaited solution to pollution issues. About The HVO Fuel HVO implies using cooking oils and similar fatty waste as fuel. That's not an entirely new concept since the use of processed vegetable oils in diesel engines has been known for more than a century. Nevertheless, it's a new hype among eco-conscious consumers because it's plant-based and very clean. Its CO2 emission and the number of PM particles are almost 90% lower than diesel and kerosene, fossil fuels that are still widely used. The base of HVO is vegetable oil, that is, used cooking oil, such as sunflower, peanut, grapeseed, etc. However, it can also be made of both food-grade and non-food-grade oils (like palm or soy), animal fat residues, and tall oil. In their original state, these liquids could not be used as fuels, so they undergo hydrotreatment. It serves to change their consistency and composition for use in standard diesel engines. Hydrotreatment involves the use of hydrogen to eliminate oxygen from the oils. This treatment takes place at very high temperatures, and then glycerides, or fat components, are separated. That's a refining process that leaves this new fuel with minimal impurities, meaning that, during its combustion, there will be no harmful by-products and gases. That means less damage to the engine itself but also drastically less pollution. The Use Of HVO In general, HVO represents an alternative to fossil fuels, especially diesel, one of the major pollutants globally. So this new energy source can be used in all engines made for diesel. It means that its most common application will be in car engines. Still, it has found its purpose in off-road and agricultural machinery, boats, and generators. Some of the major truck makers have already made vehicles powered by HVO, as in this biodiesel-powered racing truck. This new fuel from reputable manufacturers like SyntechBiofuel.com is equally usable in modern diesel engines as well as in older types that don't have electronic fuel injection. They will have almost the same performance in operation as if regular diesel was used, only with much less damage to the engine, the entire circuit, and the environment. Alternative fuels also have a huge potential to become the primary energy source for heating systems. Oil and gas still dominate in this area, but more and more households and industrial facilities are turning to alternative solutions. For instance, heat pumps are a popular yet costly solution. HVO can be an even better and more cost-effective option if you plan to go green, that is, to switch to it from standard heating systems that use oil or kerosene. This venture won't cost you extra money because there's no need for system modifications and add-ons, as would eventually be the case with heat pumps. Benefits Of Switching To HVO Fuel As said, using HVO cuts the emission of harmful gases by up to 90%, depending on what makes the base of this fuel. That results from clean combustion because there are no impurities and PM particles in this processed liquid. Moving on, it means that engines will utilize a higher percentage of fuel, so their consumption will be lower. Simply put, HVO is a cleaner and more economical solution than diesel. This fuel is also sustainable, as it's made from waste (used cooking oil and animal fat). It also emits much less greenhouse gases than other fuels. As there's no carbon in HVO, there are no toxic and potentially carcinogenic combustion by-products. Another advantage of using HVO in standard diesel engines is that there is no need for their upgrades. But if you plan to use it as a replacement for heating oil in oil-fired boilers, there might be some minimal changes to your existing system. In any case, this can bring significant savings to both individuals and companies that, for some reason, have relied on fossil fuels until now. Because it doesn't contain oxygen molecules, HVO has a fairly long shelf life. So you can store it in specialized containers for up to 10 years without fear it will lose its properties and viscosity. For the same reason, HVO's freezing point is lower than that of ordinary diesel. Also, it won't harm the environment in case of accident spillage or leak. How HVO Differ From FAME? FAME is biodiesel, which isn't the same as HVO, although there are certain similarities. For starters, both are plant-based. But what makes a significant difference is how they're made. FAME utilizes esterification, which turns fatty molecules into esters and keeps oxygen molecules in it. As explained, HVO is obtained by a refinery process that removes oxygen from fats, leaving them ester-free, clean, stable, and non-prone to oxidation. So, unlike FAME, hydrotreated vegetable oils can't spoil, thicken, or degrade during storage. HVO is the fuel of the future, and there are many good reasons for that. It's a clean, non-toxic, sustainable, and economical alternative to diesel. It contributes to reducing the global carbon footprint, bringing no harm to the living world and the environment.
