Most appliances like CFL, fans, motor-based equipment like air conditioners and pump sets are designed to work on 50 Hz sine waves. Running such types of equipment on unregulated quasi sine wave-square wave-based inverters poses a risk as regards performance and durability.

To avoid such mishaps, one must get a proper inverter for their appliances and keep them safe and in working condition throughout the year. 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.

Why Static UPS:

  • The OFF-Line UPS above 1.5KVA are highly unreliable and not available with any brand
  • The ON Line UPS always wastes 10-15% electricity. i.e. Power Loss
  • About 40% Loss due to poor power Factor is additional to the above.
  • For the applications where the fully regulated Voltage and frequency is not required, the Static UPS is the best solution
  • It provides the reliability of an ONLINE UPS and with negligible power loss when Input Mains AC is present

 

Why Lento Static Ups is Better Than Other Inverters?

The off Line UPS above 1.5KVA are highly unreliable and not available with any brand. The ON Line UPS always wastes 10-15% electricity. i.e. power Loss. About 40% Loss due to poor power Factor is additional to the above. for the applications where the fully regulated voltage and frequency is not required, the static UPS is the best solution. It provides of an Online UPS and with negligible power loss when input Mains AC is present.

 

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?

  • The output waveform is a sine wave with very low harmonic distortion and clean power, similar to that provided by a utility—essential for your expensive equipment.
  • Inductive loads, such as microwaves and motors, operate more quickly, quietly, and efficiently.
  • Pure sine-wave technology reduces both audible and electrical noise in fans, fluorescent lights, audio amplifiers, televisions, fax machines, and answering machines. It prevents computer crashes, strange printouts, and monitor glitches.

Frequently Asked Questions-

Q. What will a 1000W pure sine wave inverter run?

For example, a 100Ah lithium battery will power a 1000W inverter which is perfect for running laptops, televisions, blenders, power tools, and phone or camera chargers. A 1000W inverter is often the ideal size for most simple setups.
