What You Must Know About an Inverter Vs Non-Inverter AC?
A room air conditioner (AC) unit is more of a necessity considering the intense heat experienced during summer. An AC works on the basic premise that hot air from space is transferred outside while cool air is released back. A refrigerant (gas) is suitably used for this purpose. This article covers the topic comparing Inverter Vs Non-Inverter AC in detail.
Types of Air Conditioners Available
Apart from the non-inverter ACs or traditional ACs — split-type and window unit— an inverter AC is the improved version of the recent advancement in air-conditioning technology.
Although the two types are similar in appearance, it is their performance and efficiency that mark the difference.
Features and Specifications of Inverter Vs Non-Inverter AC
Inverter AC
It uses variable-frequency micro-processors or sensors, providing better control over the speed of the compressor motor. The frequent start-stop cycle is eliminated as the inverter AC automatically adjusts the capacity as per the requirements in space.
This results in reduced consumption of electricity units as the inverter AC lowers the rotation of the compressor motor once the cooling temperature reaches a set level on the thermostat.
Non-Inverter AC
The compressor motor runs at a constant speed. When the temperature reaches the set level, the compressor motor switches off automatically. It switches on again once the thermostat senses a rise in temperature.
Materials Used to Manufacture an AC
An air conditioner comprises various components and parts, which are made of materials such as plastic, copper, aluminum, and stainless steel.
Benefits of Using an Inverter Vs Non-Inverter AC
The functions of the two types of ACs remain the same, there are some key differences, however.
Technology at work
An inverter AC uses an inverter circuit to convert alternating current (AC) from the power supply to direct current (DC) and vice-versa. This technology helps control the compressor electromotor's speed, thereby helping to adjust the temperature.
In a non-inverter AC, there is no control over the power supply and the compressor electromotor operates at full speed or stops.
Compressor motor speed
An inverter AC has a variable-speed compressor motor, which tends to regulate the temperature. That is one of the reasons why it tends to operate in a quiet manner. In non-inverter AC, the speed of the compressor motor is fixed.
A brushless direct current (BLDC) motor is used to run the compressor in an inverter AC, which ensures steady cooling. An induction motor (asynchronous motor) is used to drive the compressor in a non-inverter AC.
Power consumption
In an inverter AC, the power consumption is the highest when switched on. However, as the speed of the compressor motor is regulated over time and it continues to operate without stopping, the power consumption remains consistent.
In a non-inverter AC, the compressor motor operates on a start-stop function at regular intervals. When it starts again, the power consumption also tends to jump in this case.
Cost factor
An inverter AC tends to be expensive. The installation, as well as repair and maintenance cost, is on the higher side, too.
However, the operational cost is low as it tends to consume electricity in an energy-efficient way.
Solar power compatibility
Many non-inverter ACs are not compatible to function on solar power. However, inverter ACs are designed to operate on solar power.
Usage and Application of Inverter ACs
An inverter AC is useful for operation in small as well as large spaces. A non-inverter is effective for usage in large spaces.
Why One Should Use Inverter ACs
An AC is useful for making intense summer heat bearable in a commercial or residential space. An inverter AC presents an additional advantage in terms of energy efficiency.
Correct Way to Use an Air Conditioner
- Ensure that the curtains and blinds in a room are drawn
- The outside AC unit should be fixed in such a way that it is away from the direct sun
- Keep the air filters clean all the time
Things to Consider While Buying an Air Conditioner
- The AC capacity is proportional to room size. Opt for one that suits your space
- Consider factors such as the amount the sunlight that enters the room as well as the floor level
- Go for an AC that remains energy-efficient. Check out the appropriate Bureau of Energy Efficiency (BEE) rating.
Ensuring Safety While Using an Air Conditioner
- Every AC, regardless of its make or model, has live electrical components, which if exposed could lead to a risk of electric shock, fire, or explosion.
- Avoid plugging your AC into an extension cord or power strip
- Hire the services of a professional technician while installing or cleaning of the AC unit.
Conclusion
The choice of an efficient AC is solely at the discretion and budget of the buyer. A non-inverter AC could be a preferred choice if the utility is not on an everyday basis or involves running the unit for several hours daily.
If you are fine with a slight rise in initial cost and looking for an energy-efficient AC unit, an inverter AC is the ideal choice.

How to Prolong the Life of Lead Acid Batteries in India 2023
The price of Lead Acid batteries rises with every coming year. This makes prolonging the battery's lifespan as much as possible. The users now look to utilize their batteries to full capacity. But maintaining them can be a daunting task. So, this is your complete guide to maximizing the lifespan of your Lead Acid Batteries in 2023.
How does a 12V Lead Acid Battery Work?
To prolong the lifespan of your battery, you need to know how it works. As you already know, Lead Acid Batteries are rechargeable. They use Lead and Sulphuric acid to function. The lead is dipped into the Sulphuric acid to allow a chemical reaction. The chemical reaction causes the battery to generate an electric charge. The same reaction is reversed to recharge the battery.
The lifespan of a Lead Acid Battery
Working conditions play an important role in determining the lifespan of a battery. Temperature is one such factor that directly affects its life. The optimal functional temperature for a 12V Lead Acid Battery is 25 degree Celsius. The increase in temperature shortens the longevity of the battery. A regulated 12V Lead Acid Battery that functions at 25 degrees Celsius has an average lifespan of 10 years. Whereas the same battery functioning at 33 degrees Celsius has an average lifespan of 5 years. The chemical reaction in a 12V Lead Acid Battery can never be halted completely. Hence, these batteries continue to discharge when not in use. Even though this happens at a very slow rate, factors like temperature increase the rate of discharge.
Ways to Maximize the Lifespan of a Lead Acid Battery
Healthy Charging Practices
You should always refrain from draining the battery completely. Letting a battery discharge below 20% causes Sulfation to occur. Sulfation accumulation blocks the electron flow which causes the charging time to increase drastically. This means increasing the charging time and ultimately reducing the productivity and lifespan of the battery. One way to prevent a battery from draining completely is to monitor battery levels closely on a daily basis.
Overcharging a battery significantly reduces the water levels in a Lead Acid Battery. As water levels reduce and temperatures rise, high damage can occur to the battery, affecting its productivity and longevity. It is important to know about the charging guidelines for the type of battery you use.
A battery has a limited number of charge cycles in its lifespan. The frequency of charging also affects a battery's life and makes a battery lose its efficiency over time.
Storage of Lead Acid Batteries
Storage location and conditions of a battery can adversely affect a battery's durability and performance. To let the lead acid battery perform at its peak capability, it must be stored in a cool, dry place with an ideal temperature. You should also avoid storing batteries in areas where there is direct sunlight or extreme freeze.
Overloading the equipment
Every battery has a regulated amount of power to distribute. Overloading the battery with numerous equipment of high power can significantly decrease its battery life.
Maintenance of a Lead Acid Battery
A battery should be cleaned and kept dry at all times. It is important to clean a battery immediately after any acidic overspill. Leaving an acidic overspill untouched for a long time may damage the battery forever.
The water level in a battery should also be monitored periodically and should be maintained at an ideal condition given by the manufacturer. While refilling the batteries with water, make sure that the water is clean and distilled.
Equalizing The Battery
The imbalance in chemicals gradually increases over time. The sulfate coatings start to accumulate reducing the total capacity of the battery. Equalization is the process of deliberately overcharging the battery to a certain level. This reduces the excess sulfate buildup in the battery.
Regular Checks
Regular maintenance is a necessary exercise you must follow to keep the battery life healthy. Checking if the vent plugs are tight and applying terminal protectors to reduce corrosion are a few things to follow.

Single-core cables are typically used for short-distance, low-voltage applications such as between a transformer and a switchboard, whereas three-core and four-core cables are typically used for longer-distance, higher-voltage applications such as between two substations.
Type of conductor
There are two types of conductors available in HT XLPE cables: Copper conductor and aluminium conductor.
Copper has a high electrical and thermal conductivity, which makes it very efficient for transmitting electricity while minimising the risk of overheating. Furthermore, corrosion resistant property of copper makes it a great choice for long-term use in harsh environments.
On the other hand, aluminium is cost-effective, making it a great option for budget-conscious projects. However, aluminium is comparatively less efficient and is more prone to oxidation and corrosion than copper. As a result, it is not suitable for applications where efficient transmission of power and corrosion resistance are of utmost importance.
Benefits of using high voltage XLPE cables over PVC cables
The difference between an XLPE cable and a PVC cable lies in the insulating material used to cover the conductors of each core of the cable. However, this simple difference provides various advantages to XLPE cables over PVC cables.
The use of XLPE offers improved electrical performance, greater flexibility and enhanced safety. The improved electrical performance of HT XLPE cables allows for more efficient energy transfer.
Additionally, their low capacitance and inductance values result in minimal voltage drop and impedance, allowing them to deliver power with fewer energy losses. As a result, XLPE cables offer around 25-30% higher current carrying capacity than PVC cables.
Finally, XLPE is comparatively more durable than PVC, thereby providing better strength to the cable with an operating temperature range of around 90℃ to -90℃.

XLPE Cable Specifications: What To Look For in A Quality Cable
Looking for a quality HT XLPE cable but not sure what specifications to consider? This article provides a detailed guide about the specifications of XLPE cables in India 2023. It also helps you select the right one for your application.
Features and specifications of XLPE cables
HT XLPE cables are commonly used for high-voltage applications where electric power is to be delivered over a long distance with high efficiency. However, there are various specifications that you need to consider to select the right cable for your application.
Safety standards
The HL XLPE cables in India are governed by IS: 8130 (1984) and IS: 7098 standards.IS: 8130 (1984) governs the quality of conductors used in the cable. IS:7098 governs the quality of the conductor screen, insulation used, armour and the inner and outer sheath.
Therefore, when buying HT XLPE cable, look for the one confirming these standards.
Voltage rating
High Voltage HT XLPE cables are available in different voltage ratings, ranging from 3.3 kV to 33 kV. Apart from this, some manufacturers also produce HT XLPE cables with a voltage rating of 66 kV. Generally, it is advised to use a cable that has a voltage rating higher than your expected load. However, the cost of the cable increases with the increase in the voltage rating. Therefore, it is advised to identify your requirement and select the cable with the most appropriate voltage rating for your application.
Number of cores
Typically, HT XLPE cables are available in 1, 3 or 4 cores. The number of cores you choose will depend on the application and the power requirements of the system. Single-core cables are the most basic type of HT XLPE cables. They are typically used in lighting circuit wiring, multi-core cables are ideal for high-voltage applications. Applications such as power transmission, electrical infrastructures, industrial machinery, agricultural equipment, etc.
Type of conductor
When choosing an HT XLPE cable for a particular application, one of the key factors to consider is the type of conductor used.
The conductor of an HT XLPE cable is typically either copper or aluminium, encased in a jacket of insulation. Copper is typically more expensive than aluminium, but it has superior thermal and electrical conductivity. In addition, copper has higher tensile strength and flexibility, which makes it ideal for longer runs of cable. On the other hand, aluminium is cheaper and is suitable for cost-sensitive applications where high efficiency is not of utmost importance.
Size of conductor
The size of the conductor is measured in terms of cross-sectional area, commonly expressed in terms of Sq.mm. The larger the size of the conductor, the higher the current carrying capacity and the higher the cost.
Generally, single-core conductors are available in sizes ranging from 35 Sq.mm to 1000 Sq.mm, whereas multi-core HT XLPE cables have a conductor size ranging from 35 Sq. mm to 400 Sq. mm.
Armour type
Armour is a metal protective covering that provides stiffness and prevents the HT XLPE cable from mechanical damage. Galvanized steel strip armour is commonly used in multi-core cables. However, you can also find aluminium and copper armours for enhanced flexibility.
Apart from protection, armour cables, such as flat-strip aluminium armour also reduce hysteresis losses and improve the efficiency of the cable.
Usage and applications of XLPE cable
Outdoor Applications
HT XLPE Cables are highly resistant to extreme temperatures, ranging from -50°C up to 150°C. This makes them ideal for applications where temperature fluctuations are common, such as in outdoor applications with extreme temperature conditions.
Underground installation
HT XLPE Cables are incredibly durable and can last up to 50 years without needing replacement. This makes them an ideal option for areas where the cables will be subjected to extreme conditions. This is also ideal where frequent repairs cannot be performed, such as in underground or marine applications.
Industrial applications
HT XLPE Cables are rated to operate up to a maximum temperature of 90℃. They can withstand short circuit temperatures of up to 250℃. In addition, these cables are generally flame retardant and self-extinguishing, which minimises the risk of fire.
This makes it ideal for aerospace and other industrial applications where high current capacity is required, without compromising safety.
High-power transmission applications
HT XLPE Cables can transmit high-voltage electrical power over long distances, making them ideal for electricity transmission from one power station to another.
Things to consider while buying XLPE cable
Every XLPE cable has a code that determines its specifications, such as the type of conductor, insulation, armour and outer sheathing used in the cable.
The table below provides information about the different elements of the code.
| Code | Constituent |
| A | Aluminium conductor |
| C | Copper conductor |
| 2X | XLPE Insulation |
| W | Round Steel Armour |
| F | Flat steel strip armour |
| Y | PVC outer sheathing |
For example, an HT XLPE cable with code "A2XFY" has an aluminium conductor, with XLPE insulation, flat steel strip armour and a PVC outer sheathing. Therefore, look for the code and select the best-suited cable for your application.
Apart from that, always look for the cables that comply with the Indian standards for XLPE cables, like IS: 8130 (1984) and IS: 7098. This ensures the safety and reliability of the cable.
