How Inverter Works: A Complete Technical Breakdown
The uninterrupted power supply is a basic necessity in the existing scenario, where offices are run from anywhere and at any time. The cost-effective and simple solution to meet such needs is inverters. These devices accompanied with battery help offer an effective backup regardless of the time of power outage. The duration however depends on the type of battery.
Apart from these basic facts, there are more technical aspects associated with inverters, such as ‘what is an inverter and how does it work’. These are essential to be known for informed decision-making. Further, their benefits in terms of cost savings and other boons must also be well understood to decide their need in your life. So, read on to be enlightened.
What is an Inverter?
An inverter is an electronic device that provides an Alternating Current (AC) power supply from the stored Direct Current (DC). The DC power can be obtained from the main grid or solar panel and stored in the inverter battery. The stored energy as DC is then converted into AC by inverter to power the appliances.
Types of Inverters
There are three types of inverters commonly available and used in India. They are described below:
Square Wave Inverters
They generate AC current in the square waveform, making it comparatively less efficient compared to pure and modified sine wave inverters. They are easily available in the market. These inverters are well-suited for applications where only some devices are to be connected to the inverter or the ones that require minimal power for startup. Also, they make noise.
Modified Sine-Wave Inverters
They offer better efficiency and compatibility with the appliances while allowing connection with multiple devices simultaneously. They are well-suited for powering the appliances that do not need a start-up surge of power and the ones with resistive loads such as electric heaters, ovens, coffee machines and others. These inverters are cost-effective as compared to pure sine wave inverters.
The downside associated with these inverters is the few minutes taken to get on and off during the power outages. They can also impact the appliance performance intermittently at irregular periods, causing flickering of lights and noise generation in appliances.
Pure Sine-Wave Inverters
These are the most suitable inverters for usage due to their production of smooth and consistent current. They are reliable, and their power supply matches that of the main grid power supply. These inverters can be used for appliances with heavy power requirements and can be used simultaneously with multiple devices. They are also compatible with sensitive electronic devices. However, they are more costly compared to other options due to their better performance.
How Does an Inverter Work?
To understand inverter how does it work, here is a stepwise insight into its mechanism:
Step 1: The inverter battery stores the electricity available from the main supply. It can also obtain electricity from renewable resource such as solar energy, where electricity generated from solar panels is used for storage. If the supply is in AC, it is converted into DC for storage.
Step 2: In the case of a power outage, the stored electricity in DC is converted back to AC by the inverter. This supply reaches the connected appliances and provides them with power to start again and run continuously until the electricity source in the battery runs out or until the power is back.
Step 3: Once the main supply is back, the appliances get direct electricity from the main source. The inverter battery starts charging again.
Hence, this is how a power inverter works to offer an uninterrupted power supply.

Solar energy has proved to be the most dependable and sustainable solution for power generation today. However, if you want to make the best use of solar power for your homes or workplaces, you need to understand solar inverters and their systems better. A solar power system relies on solar inverters to transform the direct current output from solar panels into an alternating current. This is how solar energy is used in regular devices. However, there are many options available in the market when it comes to selecting the right solar inverter for your needs. Are you also struggling to choose between options that seem equally appealing? Well, worry no more, as this article explains the different types of solar inverters, helping you make better decisions.
Solar Inverter Types
Solar power systems are broadly categorised into three types, namely, on-grid, off-grid, and hybrid inverters. The different types of solar inverters operate to convert solar-generated Direct Current into Alternating Current while providing electricity to most appliances. They are available in capacity ranges of 2V DC, 48V DC, and 96V DC. Let’s take a look at each type to understand their systems better.
String Inverters
One type of inverter for solar power is the string inverter. Solar systems installed in residential homes primarily rely on string inverter systems. They connect a series of strings of solar panels to a single inverter that converts the DC power into AC power. The system operates as one central control point which regulates every panel within its network.
Pros:
- Cost-effective
- Easy to install and maintain
- Suitable for systems with uniform sunlight exposure
Cons:
- Decreased performance when any one panel is shaded or malfunctioning.

Microinverters work best in installations where panels are positioned in various directions or shadowed areas. Microinverters maximize each panel's power output, making them a worthwhile investment despite the higher cost.
Power Optimizers
Power optimizers use elements of both string and micro-inverters. These devices are mounted side-by-side with solar panels in the same way as microinverters do. However, power optimizers condition and optimize DC power before sending it to a central inverter for conversion to AC power.
Pros:
- Enhanced performance in shaded conditions
- Lower cost than microinverters
- Units for centralized control and optimal power output exist within one system.
Cons:
- Slightly more expensive than traditional string inverters
- Dependence on a central inverter for final power conversion
- Installation can be complex
The combination of cost reduction and effectiveness makes power optimizers an optimal solution. Such systems prove effective for circumstances where shading affects different areas of the array or when multiple panels face different directions.
On-Grid Solar Inverter
The most common solar inverters operating on the power grid are on-grid solar inverters, also called grid-tied inverters and are routinely used in urban regions. The devices operate with solar power systems that have connections to utility grids. On Grid Solar Inverter devices facilitate solar panel DC-to-AC power conversion and return electricity to the grid when excess power is available.
Key Features:
- The inverter automatically turns off because of anti-islanding protection systems during power outages, thereby maintaining safety.
- The Bi-Directional Meter tracks electricity that goes into the grid and the electricity that comes out from the grid.
Suitable For:
- Institutional customers powered by the electric company's network
- Locations with reliable grid power
- Household consumers need devices that reduce their monthly electric bills.
People choose on-grid inverters above others because they function without requiring batteries, which results in both reduced costs and simplified maintenance requirements.
Off-Grid Solar Inverter
Also called a stand-alone or solar battery inverter, an Off Grid Solar Inverter provides power generation in areas without access to grid-based electricity. These rely on battery banks to store excess power generated by solar panels. The stored energy from the solar panels feeds appliances when there is no power or insufficient sunlight.
Key Features:
- The system includes storage elements that retain excess power, which can be retrieved later.
- This system operates without receiving power from the utility power grid.
Suitable For:
- Remote locations without grid access

Maximize Your Inverter Performance: A Simple Guide in India 2023
People looking for ways to get the most out of their power inverter have come to the right place. This blog post will offer tips and tricks to help maximize the inverter, whether at home, a small business or a large corporation. This post covers offers essential tips to help maximize a power inverter and safety tips for installation and usage.
Inverters improve efficiency
An inverter is a machine that can convert DC voltage to AC voltage. Batteries usually produce direct current (DC), whereas most household electronic items use alternating current (AC). Therefore, inverters work as AC to DC power conversion machines to help operate electronic equipment at home more efficiently.
Nine tips to maximize the performance of a power inverter
- Choose the right voltage inverter: One must choose an inverter with equal DC voltage as the battery, generally 12 to 24 volts. It will help to operate all the appliances which are connected to the inverter efficiently.
- Use surge protection: To protect one's devices from sudden power spikes, one must use a surge protector when plugging them into a power inverter. This is used as a safety precaution.
- Use heavy-duty extension cords: When connecting a power inverter to the devices, one must use heavy-duty extension cords. It will ensure that the power is delivered to one's devices without any loss of voltage or current. Moreover, heavy-duty cords are more efficient in carrying high voltage.
- Keep electrodes well connected: Connect the battery's positive and negative electrodes correctly and ensure they are well connected to the terminals of the inverter. Loose connections may cause power loss and initiate electric sparks which may cause an electrical hazard.
- Use the power inverter correctly: Remember that charging and inverting are not possible simultaneously. Always use the inverter for its designed purpose; otherwise, it can get damaged. Keep at least a five-second gap between charging and inverting the device.
- Keep it in the correct place: Place it in a dry, well-ventilated, cool area to avoid overheating and damaging any devices. Keep a minimum 20cm distance from walls, water, and other sources of electric shock. Also, keep the bottom of the inverter slightly above the surface to ensure better ventilation and heat dissipation.
- Never open the inverter case: One must never open the inverter case by themselves. If it needs service, take it to a qualified technician.
- Keep the inverter on the ground: Always remember to keep it on the ground before connecting with powers. If it is not grounded, it can create an electric shock and may cause severe accidents.
- Install a fuse: To protect the devices from sudden power surges, one must install a fuse on the output side of one's power inverter. It will help prevent any damage to one's devices if there is an unexpected power spike.
Safety Tips on Installation and Usage
Before installing inverters at home or offices, there are some key safety points that one needs to keep in mind.
- Choose a flat surface, whether vertical or horizontal, for installation.
- Avoid installing inverters in places that are exposed to heat, such as direct sunlight, heat exchangers, radiators etc.
- Avoid keeping inverters in humid spaces.
- Do not touch any component or wire of the inverter with wet hands. It will cause a major accident and damage to the equipment.
- Always keep some space at the bottom of the inverter. It will ensure better heat dissipation and ventilation.
Inverters are an important part of any business or home. Following these tips can maximize the inverter's efficiency and keep one's devices safe.

The Ultimate Guide to Selecting the Right 12V Inverter in India 2023
Inverters are a great machine to ensure your household or business equipment run safely and efficiently. But with different types of inverters available in the market, it is a daunting task to find the perfect one for your usage. If you are looking to buy a 12v inverter for residential or commercial use but need help deciding what will work best for you, we are here to make it easy for you.
We have compiled a list of five important things you need to know about 12v inverters to make an informed decision. We'll cover the types and safety tips of the products that will work best for you. So, let's get started.
Using 12V Inverters
A 12V inverter is a device that transforms 12V battery power from direct current (DC) to alternating current (AC). This AC power is used to operate various electrical devices. 12V Inverters are commonly used in small cars, boats, and in homes and small businesses appliances as the power required for such devices is usually less than 1000 watts.
In case you need more than 1000 to 5000 watts power, you should opt for a higher voltage inverter.
12V inverters have numerous residential and commercial applications.
Household: TVs, sound systems, refrigerators, lighting systems, cooking equipment etc.
Office use: Laptops, desktops, printers, monitors etc.
Other: Vehicles, power tools etc.
5 Things You Need to Know About 12v Inverter
Below 5 things you need to know about 12v inverters before you buy one:
Know your power requirements
You'll need to decide what type of power your appliances need. The power of your inverter should be 8-10% higher than your appliances' original power supply. To know the DC draw of your inverter, you can divide the AC draw of your appliance by 12, and you will get a close estimate of the power of your appliances.
Calculation
Power of inverter is calculated in VA (volt-ampere) or KVA (Kilo volt-ampere)
Power (in VA) = AC voltage X AC current (Amp)
Power (in Watt) = AC voltage X AC current X PF (Power factor = 0.8 considered for home usage)
Suppose you want to run 5 fans (80 watt each), three tube lights, five CFL, three LED bulbs, and also two television, which use 40, 20, 7, and 120 Watts, respectively.
The total power requirement will be
5x80+6x40+3x20+1x120= 940 watt
So, power in KVA = KW power / PF (0.8 for home)
= 0.94 / 0.8
= 1.175 KVA
So, as per the available standard rating, you need to select 1.5 KVA inverter
The number of output
Before selecting the inverter, plan how many equipment you need to operate through it. Most inverters have two or three outputs. A single output inverter may be sufficient if you only need to power one device. You'll need to buy an inverter with multiple outputs if you want to power multiple devices.
Size of the inverter
Measuring the size of 12V inverter is important because you need to fit the inverter and battery pack in the specific space available. Higher wattage inverters need larger space. Also, various brands offer different battery sizes and features. While deciding the inverter size, you must consider the maximum power used at a time, and your inverter should have 50% more battery cover.
Efficiency rating
When selecting a 12V inverter, understand the wattage of the appliances you plan to power. The wattage rating of the inverter should be higher than the wattage of the appliance or device you plan to power. You can check the inverter's wattage in the product catalogue and user manual.
Moreover, for maximum effiency, it is essential to ensure that the battery rating should match the rating of the inverter
Warranty
Warranty is one of the vital things to know about any inverter. It reflects the brand’s and product’s reliability. Many manufacturers offer warranties that cover defects in materials and workmanship for up to one year from purchase. It is also important to check the manufacturer's return policy in case you need to return the unit for any reason.
Safety Tips:
- Inspect the battery water level frequently
- Avoid connecting the inverter to high-load appliances
- Use standard insulated wires for connections
- Ensure proper earthing
Final words:
12V inverters are a great choice for those who are looking to buy commercial and home products. They are cost-effective, easy to install, and reliable.
