What is Low Frequency Inverter and Advatages of Low Frequency Power Inverter?


Using an inverter, you may produce AC power for your home's electrical appliances and electronics from the DC power stored in a battery (12 volts of direct current). The final AC frequency is determined by the type of equipment used to generate the current. Inverters exist in a wide variety of shapes and sizes, and they can be customized in various ways. Frequency inverters convert alternating current (AC) to direct current (DC).

There are two basic types of power inverters:

· Low-frequency inverter

· High-frequency inverter

We'll talk about low-frequency inverters in this section.

LFI: Low-Frequency Inverter

For increasing voltage, a low-frequency inverter uses a low-frequency transformer. Once the DC is converted into a low-frequency alternating current, it can be used. An inverter with a low frequency can perform a wide range of tasks. Alternating current (AC) is produced by converting DC to AC using transistors (AC). About 120 times a day, their transistors are activated and deactivated. These low-frequency power converters and inverter/chargers are the most reliable and long-lasting.

Because of the flywheel effect inherent in the physical size of a transformer's iron, a giant iron core transformer can absorb surge loads. Due to the slower switching frequency necessary to generate AC power, this inverter has the most extensive and robust field-effect transistors that can run cooler.

Sizeable off-grid power systems are best suited for these devices built for high-power applications. Because of this, inverters in this category typically have power outputs in the thousands, typically between 2000W and 3000W.

For a low-frequency transformer, the term "working frequency" refers to the power frequency of either 50Hz or 60Hz. There is a gradual alteration in the signal's waveform.

With little or no access to conventional energy, low-frequency inverters remain an excellent purchase for anyone with many electrical solid appliances. An appropriate solar power kit and a low-frequency inverter can give a stable backup supply and eliminate the need for a traditional utility grid. A low-frequency inverter is a more reliable long-term investment than a high-frequency inverter because of the low-frequency inverter's low failure rate. They are, in fact, more prominent, more vital, and more ferocious than us.

Among the Low-Frequency Inverter's advantages

A UPS (uninterruptible power supply) features a low-frequency inverter. Bypass mode, power-saving mode, and various charging options are the primary functions of this built-in battery charger.

Multiple DC voltages can be input, dual output voltages (120/240VAC) are provided, and integrated battery chargers and shore power transfer relay for different chemical batteries are available on these inverters.

Advantages over high-frequency inverters

There are two areas where low frequency power inverter has an advantage over a high-frequency inverter:

· If the nominal power level is 300 percent of the peak power level, low-frequency inverters can function at that level for several seconds. Still, high-frequency inverters can operate at such a level for a minimum period.

· High-frequency inverters are less dependable and sturdier than low-frequency inverters because they use smaller transformers.

Types of low-frequency inverters

Following are the types of low-frequency inverters:

· A continuous power rating of 2kVA (XTM1500: 1.5kVA) is provided by the 12V-XTM inverter/charger low frequency inverter. For up to five seconds, the XTM1500 can deliver 4.8kVA (XTM1500 can deliver 3.5kVA). Because of its tremendous surge power capacity, it can supply loads with a high startup current without incident. It is possible to regulate the charging current from 0 to 100 dc.

· 24V-XTM inverter/charger low frequency inverter has a continuous power rating of 3kVA (XTM2000: 2kVA), 30 minute power rating of 3.5kVA (XTM2000: 2.4kVA), and can supply 9kVA (XTM2000: 6kVA) for up to 5 seconds. A range of 0 to 90Adc can be selected for the battery charge current.

· The 48V-XTM inverter/charger low frequency inverter has a continuous power rating of 3.5kVA (XTM2600: 2kVA), a 30 minute power rating of 4kVA (XTM2600: 2.6kVA) and can supply 10.5kVA (XTM2600: 6.5kVA) for up to 5 seconds. It is possible to set the battery charge current between 0 and 50ADC (XTM2600: 30A)

Pros and cons of Low-frequency inverter

The advantages and disadvantages of using a Low-Frequency Inverter are as follows:


Among the advantages of a low-frequency inverter are:

· For high-surge loads, it performs well

· It's quieter and more energy-efficient.


The following are some drawbacks to using a low-frequency inverter:

· It is heavier than other frequency inverters.

· Because of this, it costs extra.


What is the function of a low-frequency inverter?

"Low frequency" refers to how Low-Frequency inverters employ high-speed transistors to convert DC electricity into AC power. Still, they drive transistors at the same frequency (60Hz or 50Hz) as the AC sine wave output voltage.


What is the function of a frequency inverter?

You may control an AC motor's speed with frequency inverters, electronic equipment. Only a fixed speed is available based on the number of poles and supply frequency of a power supply system when AC motors are driven directly from that system.


Is low frequency inverter expensive?

Low-frequency inverters are more expensive than high-frequency inverters because of their higher peak performance and reliability. If you don't use a lot of energy and need to power a few tiny gadgets, a high-frequency inverter is the best option for you.

If you're establishing an off-grid power system with no substantial power limits or if you're running powerful appliances and gadgets with electric motors like power tools, washing machines, vacuum cleaners, and air conditioners, then low-frequency inverters will provide you with the best solution.

Low-frequency inverters are also ideal for consumers who want to power various kitchen appliances, such as refrigerators, microwaves, dishwashers, and ovens.


Low-frequency inverters are still a significant expenditure for people with a large number of powerful equipment in areas where standard power is limited or non-existent. When paired with an appropriate solar kit, the low-frequency inverter may not only provide a solid backup power option but can also totally replace conventional electricity with the same quality power source.
