A pure sine wave inverter is a type of power inverter that is becoming increasingly popular in Bangladesh as a reliable and high-quality alternative to traditional energy sources. Unlike traditional inverters that produce a square waveform, pure sine wave inverters generate a smooth and continuous waveform that is similar to the waveform generated by the utility grid.

Pure sine wave inverters are commonly used in residential and commercial solar energy systems, as well as in a wide range of other applications where a clean and stable power source is required, such as in medical equipment, sensitive electronics, and motors. They are known for their improved performance, efficiency, and increased lifespan of connected equipment, as well as their compatibility with a wide range of appliances and equipment.


Inverters, like AC power supplies, use DC electrical energy stored in a battery or battery bank. They use electronics and transformers to convert DC to AC and then increase the voltage to 220V. Even when compared to generators, inverters are extremely efficient because they only consume DC power in proportion to the amount of AC power they produce.


With sufficient solar panels, an inverter system can easily replace any power source. The long-term benefits of such an investment are self-evident.Lento uses pure sine wave technology in their inverters, UPS and power supplies. The Sine wave inverters output stable frequency and voltage, mimicking mains power supply, making it perfectly suitable to power expensive equipment, especially inductive loads that do not work well on square waves.


Lento DSP sine wave Static UPS and inverters are designed to provide stable 50 Hz sine wave irrespective of load and battery voltage, making them the most suitable for inductive, capacitive and non-resistive loads. Importantly, Lento’s inverters and UPS are designed to deliver instantaneous high current during start-up, especially in the case of air conditioners and refrigerators, with safety cut out when battery voltage goes lower than a specified point to avoid brownouts and burning of motors.

What is an inverter?

An inverter converts DC voltage to alternating current voltage. In most cases, the input DC voltage is lower, while the output AC voltage is equal to the grid supply voltage, which can be 120 or 240 volts depending on the country.

The inverter can be designed as a standalone piece of equipment for applications such as solar power or as a backup power supply using batteries that are charged separately.

The other configuration is when it is part of a larger circuit, such as a power supply unit, also known as a UPS. In this case, the rectified mains AC in the PSU powers the inverter, while the rectified AC in the UPS powers it when there is power and the batteries power it when there is no power.

Inverters are classified according to the shape of the switching waveform. These have various circuit configurations, efficiencies, benefits, and drawbacks.

An inverter generates alternating current voltage from direct current power sources and is useful for powering electronics and electrical equipment rated at alternating current mains voltage. Furthermore, they are widely used in the inverting stages of switched mode power supplies. The circuits are classified based on their switching technology and switch type, as well as their waveform, frequency, and output waveform.

What is a Pure Sine Wave Inverter?

Before we get into the benefits of using pure sine wave inverters in your home, it's important to understand what they are and how they work. Pure sine wave inverters produce AC power that closely resembles the real thing - a steady, continuous sine wave with smooth, periodic oscillations. As a result, the price of this solar inverter for home is quite high. Furthermore, certain devices are only compatible with these inverters. If you use another type of inverter, your devices may malfunction or be damaged.

Let us now look at the advantages of pure sine wave inverters.


Advantages of Pure Sine Wave Inverter-

  1. Consistent, smoother current flow

A pure sine wave inverter, as opposed to modified sine wave inverters, provides consistent, uninterrupted power to your devices. What makes this so great? Because modified sine wave inverters produce power in a step pattern, the voltage abruptly rises and falls, resulting in inconsistent current flow to your devices, which can be harmful in the long run. When shopping for a solar inverter for your home, it's best to go with pure sine wave inverters.

  1. Produces same current as power grids

A pure sine wave produces a wave that is very similar to the smooth waveform generated by mains electricity. That is, there is no discernible difference between plugging your devices into these inverters and plugging them into a wall outlet.

This, of course, means that you can use almost any device during a power outage.

  1. Devices are at low risk

The smooth waveform produced by a pure sine wave inverter also protects your high-end electronics from damage during power outages. After all, you don't want your gaming computer or oxygen machine to fail during a power outage.

Furthermore, using modified sine wave inverters with AC-powered devices such as microwaves and refrigerators can generate excessive waste heat, putting your devices at risk. Pure sine wave inverters, on the other hand, pose no threat to any of your devices.

  1. Quiet Operation

When using standard inverters, you may occasionally hear an annoying humming sound from lights and fans. When using a pure wave inverter, this is not the case. The waves produced by these inverters make very little noise. Pure wave inverters are simply cleaner, cooler, and quieter.

  1. Compatibility With a Variety of Devices

Because of the grid-like wave pattern and power these inverters produce, almost all devices work with them, including:

  1. Appliances with AC motors, such as refrigerators, compressors or microwaves.
  2. Audio equipment, video equipment, satellite systems, and microwave towers.
  3. Other devices that use the same type of technology include bread makers, certain battery chargers, and light dimmers.
  4. Many CPAP devices for sleep apnea and oxygen concentrators that require a power source.
  5. Furthermore, there is no need to purchase a separate UPS for your computer because a pure wave inverter is more than capable of powering your PC.

So why use a pure sine wave inverter?

  • Improved compatibility: Pure sine wave inverters are more compatible with a wider range of appliances and electronics than other types of inverters, as they produce a waveform that more closely resembles the AC power supplied by utility companies.
  • Increased efficiency: Pure sine wave inverters can increase the efficiency of connected loads, as they are less likely to introduce distortions or other issues that can reduce the efficiency of the loads.
  • Enhanced safety: Pure sine wave inverters are generally considered to be safer to use than other types of inverters, as they produce a waveform that is less likely to cause electrical interference or damage to connected equipment.
  • Lower harmonic distortion: Pure sine wave inverters produce waveforms with lower harmonic distortion than other types of inverters, which can improve the performance of connected equipment and reduce the risk of electrical interference.

Typically, you'll need pure sine wave inverters for sensitive equipment, newer TV's, CFL light bulbs, and appliances with AC motors (microwaves and refrigerators).

Q: What does the 6kVA rating mean for a pure sine wave inverter?

A: The 6kVA rating refers to the maximum apparent power output of the inverter, which is a measure of the total power that the inverter can supply to connected loads. Apparent power is measured in volt-amperes (VA), and a 6kVA inverter is rated to supply up to 6,000 VA of apparent power. However, the actual power output of the inverter, measured in watts (W), will depend on the efficiency of the inverter and the specific loads it's powering.

Q: What does the 120V rating mean for a pure sine wave inverter?

A: The 120V rating refers to the nominal AC voltage output of the inverter. This means that the inverter is designed to produce an AC waveform with a nominal voltage of 120V. Keep in mind that the actual voltage output may fluctuate based on the load on the inverter and other factors, but the nominal voltage is a reference point that is used to describe the inverter's performance.
