Pure Sine Wave Inverter Price in Sri Lanka 2023

Many appliances only work with alternating current voltage, which shouldn't be a problem if you have a wall socket nearby, right? However, in the event of a power outage or other emergency, you're pretty much stuck with batteries. And you don't want to be left with only 12V if the power goes out. Pure sine wave inverters fall into this category. These devices convert low voltage DC to 110V or 120V AC electricity, which is used by household appliances. 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.

What is a Sine Wave Inverter?

Sine wave inverters are a type of power inverter that generates an output voltage waveform comparable to that of grid-connected AC power sources. This type of inverter is commonly employed in power systems where sensitive equipment or loads demand a high-quality, sinusoidal waveform.

How does a sine wave inverter work?

A sine wave inverter's fundamental operation is straightforward. The inverter transforms DC input voltage from a battery or other power source into AC output voltage. This output voltage is then routed via a transformer to boost the voltage before being delivered to the load.

To maintain a smooth, sinusoidal waveform, the inverter continually analyses the input voltage and changes the output frequency and amplitude. This guarantees that the output voltage is of the greatest quality and may be used with sensitive equipment.

Microwaves, motors, and some medical equipment require a clean AC signal, hence the sine wave is required.

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.

Types of Sine Wave Inverters –

Sine wave inverters are classified into two types: Pure Sine Wave Invertersand Modified Sine Wave Inverters. Pure sine wave inverters generate a highly clean, pure alternating current signal, whereas modified sine wave inverters are less costly but create a somewhat less clean signal. Modified sine wave inverters are often the least costly sine wave inverters since they generate the easiest sort of sine wave. Their polarity rapidly shifts from positive to negative, resulting in a waveform that resembles a square wave rather than the rounded arc seen with pure sine inverters.This allows most appliances to still be connected to the inverter without risk of overheating. It is used for simple appliances as there are lots of equipment that it cannot support.

However, if your priority lies in ensuring that your appliances are absolutely safe, the most secure way of ensuring the same is to invest in a pure sine wave inverter. This kind of inverter is preferred by those who want the benefits of a sine wave inverter, but money is a concern.

Devices that require pure sine wave inverters include:

  • Appliances with AC motors, such as refrigerators, compressors or microwaves.
  • Audio equipment, video equipment, satellite systems, and microwave towers.
  • Other devices that use the same type of technology include bread makers, certain battery chargers, and light dimmers.
  • Many CPAP devices for sleep apnea and oxygen concentrators that require a power source.

Frequently Asked Questions about Pure Sine Wave Inverter-

Q. Which is the best pure sine wave inverter?

Q. How do you choose a pure sine wave inverter?

When choosing your sine waveform inverters, you need to make sure you are selecting an inverter that covers your total watt draw. Also be sure to account for a possible surge draw. Most devices such as laser printers, pumps and compressors take a lot more energy to get started, and it isn't always listed on the device.

Q. How many batteries are needed for a 2000 watt inverter?

Typically two batteries are needed for a 2,000 watt inverter like the part # 34278156 that you referenced.

Q. How long will a 12V battery last with a 2000 watt inverter?

Let's say you purchase a 2000-watt inverter 12 Volt. If you max out the inverter at 2000 watts, you are pulling 2000 watts /12 volts = 166.6 DC amps per hour. If you use a 200-amp 12-volt battery, you would divide the 200-amp battery / 166.6 amps = 1.2 hours of run time.

Q. How do I calculate what size inverter I need?

CALCULATE THE INVERTER'S REQUIRED CAPACITY
Recall, the total power consumed by your home (total wattage) – 460W. Therefore, required VA rating of inverter = (460/0.8) = 575VA. This is approximately a 0.6kVA (600VA).

Q. Is pure sine wave inverter worth it?

If your electronics don't fall into either of those two categories, then it's extremely unlikely that a modified sine wave inverter will do any damage. While a pure sine wave inverter is safe for use with a wider range of devices, the greater cost associated with pure sine wave inverters isn't always worth it.

Q. What does a pure sine wave inverter do?

A pure sine wave inverter is a device that converts direct current (DC) such as what's produced by a solar system or RV batteries, to usable alternating current (AC) that most appliances use. What is this? These “pure sine waves” ensure smooth and steady voltage, just like in the power grid.

Q. Which inverter is best sine wave or pure sine wave?

Modified sine wave inverters are still a viable option if you have limited, simple appliances to power and aren't as concerned with efficiency. However, if you want the peace of mind of knowing your appliances and devices will run safely and at the highest efficiency, we recommend purchasing a pure sine wave inverter.

Q. What appliances need pure sine wave?

Pure sine wave output is always needed for a grid-tie solar system. It is generally needed for newer LED TVs, CFL light bulbs, and inductive loads like brushless motors. Clocks and audio equipment will behave much better on a pure sine wave.
