What is Inverter?

An inverter on solar power is a critical component of a solar panel system. Solar panels convert sunlight into direct current (DC) electricity, which can then be used to power homes or businesses. However, most electrical appliances and devices run on alternating current (AC) power, which means the DC electricity generated by solar panels needs to be converted into AC power using an inverter. Inverters for solar power systems come in various types, including string inverters, microinverters, and power optimizers. String inverters are one of the most common types, converting DC power generated by several solar panels connected in a series into AC power. Microinverters, on the other hand, are installed on each solar panel, converting the DC power that each panel generates into AC power. Power optimizers are a hybrid of the two, installed on each solar panel to optimize the performance of the entire system. The main benefit of using an inverter on solar power is the ability to use the electricity generated by solar panels to power a home or business. It also extends the life of the battery backup system by changing DC power to AC power, which can be used to power appliances and devices even when there is no sunlight. In addition, it ensures that the converted AC electricity is safe and reliable for use by household appliances and other electrical devices. Inverters for solar power systems play a critical role in the conversion of DC electricity generated by solar panels into usable AC electricity. They enable the use of renewable energy sources like solar power by providing efficient, reliable, and cost-effective AC power for homes, businesses, and communities.

History of Inverter

The history of the inverter dates back to the 19th century when Nikola Tesla discovered the principles of alternating current (AC) that allowed the conversion of DC power into AC power. In the early years, AC power was not widely used because it was expensive and not efficient. It was in the mid-20th century that the development of solid-state technology allowed for the creation of efficient and affordable inverters. The first electronic inverter was developed in the 1950s for use in military applications. It was used to power radar equipment and communication systems. In the following years, inverters were developed for commercial and residential applications. They were used for emergency power supply systems, solar power systems, and to power appliances and electronic devices in remote locations. With the advancement of technology, new types of inverters were developed, including pure sine wave and modified sine wave inverters. These types of inverters were designed to provide better and cleaner power output for sensitive electronics and appliances. Today, inverters are an essential part of our daily lives. They are used in a wide range of applications, from powering our homes and offices to powering portable electronic devices. With the increasing demand for renewable energy sources, inverters are also an essential component of solar power and other renewable energy systems.

Types of Inverter

There are mainly three types of inverters: 1. Pure Sine Wave Inverter: This type of inverter produces an output waveform that is similar to utility or grid power. It provides a high-quality power supply and is considered the most reliable and efficient type of inverter. It is used for sensitive electronic equipment and appliances that require a stable and clean power supply. 2. Modified Sine Wave Inverter: This type of inverter is the most common and widely used. It produces a waveform that is a step waveform, and it is less expensive compared to pure sine wave inverters. It is used for appliances like fans, pumps, and lighting. 3. Square Wave Inverter: This type of inverter produces an output waveform that is similar to a square waveform. It is the cheapest and least efficient type of inverter. It is used for simple appliances and devices like incandescent bulbs, hand tools, and heaters. Each type of inverter has its advantages and disadvantages. Pure sine wave inverters are the most efficient, but they are also expensive. Modified sine wave inverters are more affordable, but they may not be suitable for sensitive electronics. Square wave inverters are the least expensive but, they may damage electronic equipment and appliances. It is crucial to choose the right type of inverter based on the appliances and devices you want to power.

What are the Different Sizes of Inverter?

There are different sizes of inverters available in the market. Here are some of the most common sizes: 1. Small Inverters: Small inverters are compact and portable units that can power small electronic devices such as laptops, smartphones, and small appliances. They typically range from 100W to 500W and are ideal for camping, road trips, or emergency backup power. 2. Medium Inverters: Medium inverters are more powerful than small inverters and can power larger appliances such as refrigerators, televisions, and power tools. They typically range from 1,000W to 3,000W and are suitable for small offices, residential homes, and outdoor activities. 3. Large Inverters: Large inverters are industrial-grade units that can power heavy-duty equipment such as air conditioners, pumps, and large machinery. They typically range from 5,000W to 50,000W and are used in factories, warehouses, and other commercial or industrial settings. 4. Grid-Tie Inverters: Grid-tie inverters are used in solar power systems and convert DC power from solar panels into AC power that can be used to power homes or businesses. They typically range from 1,000W to 10,000W and are designed to synchronize with the electrical grid. 5. Pure Sine Wave Inverters: Pure sine wave inverters are designed to produce clean and stable AC power that is similar to the power supplied by utility companies. They are ideal for powering sensitive electronic devices such as medical equipment, computers, and audio systems and are available in various sizes depending on the power requirement.

How Does Inverter Work?

An inverter works by converting direct current (DC) power to alternating current (AC) power. In electronics, AC power is used to power most electrical appliances. The following are the steps to understand how an inverter works: 1. Conversion of DC to AC: The fundamental function of an inverter is to convert DC power to AC power. A DC power source, either a battery, DC generator, or solar panels, provides the input power to the inverter. 2. Conversion of voltage: The inverter then increases the DC voltage to the required level for AC power. The DC voltage is converted to high-frequency AC voltage, typically using electronic switches such as MOSFETs or IGBTs. 3. Conversion of waveform: The next step is to convert the high-frequency AC voltage into a desired waveform, such as a pure sine wave, modified sine wave, or square wave. The type of waveform produced depends on the design of the inverter and the intended use. 4. Filtering: The filtered output is then sent through an output filter to remove any unwanted harmonics and noise and to ensure a smooth waveform. The filter also helps to maintain the voltage and frequency at a constant and controlled level. 5. Output: The final step is to provide the AC power output in the desired form to the connected electrical appliances. In summary, an inverter works by converting DC power to AC power by increasing the DC voltage to the required level, converting the DC voltage into high-frequency AC voltage, and finally filtering the output to remove harmonics and noise, and then providing the AC output in the desired waveform to power electrical appliances.


In conclusion, an inverter is an electrical device that converts DC power into AC power. This technology is widely used in homes, offices, industries, and solar power systems, offering a reliable and affordable way to power various electrical devices and equipment. The size of the inverter depends on the power requirements, with small inverters ideal for portable devices, medium inverters for small homes and offices, and large inverters for industrial applications. Additionally, pure sine wave inverters are another type of inverter that produces clean and stable AC power, ideal for powering sensitive electronic devices. The market for inverters is diverse, and choosing the right one depends on the intended use and power requirements.
