What Is a Low-Frequency Pure Sine Wave Power Inverter?

This is a low-frequency output power inverter is device that converts battery DC power into AC power. It utilizes super-fast power transistors in transforming DC to AC power. Additionally, it put together the functions of the inverter function and the MPPT/PWM solar charger controller.

This power inverter is built with a powerful toroidal/square transformer that provides excellent isolation. The stable power supply is also supported by strong protection measures that prevent the battery from destruction.

The Low-frequency pure sine power inverter gets the name from their use of high-speed power transistors when transforming Direct current to Alternating current. It is built with a strong toroidal/square transformer that provides excellent isolation. The consistent power supply includes excellent protection measures to prevent the battery from being destroyed and to guarantee that the load is provided.

What Is High-Frequency Pure Sine Wave Power Inverter?

A High-frequency pure sine wave power inverter is a device that converts DC into AC operating on frequencies of above 50kHz. This type of power inverter is also referred to as the TL inverter or the transformer-less inverter. Unlike the low-frequency inverter, this inverter delivers similar power and at a higher frequency of above 50khz using a smaller transformer.

With a smaller transformer, the high-frequency pure sine wave power inverter surges less and for shorter periods compared to the low-frequency power inverter. The main function of this device is to provide an uninterruptible power supply in a small package to various applicable appliances, mostly in industrial settings, as well as on some home and office appliances.

Most high-frequency power inverter comes fitted with a large LCD screen with easy-to-use buttons. You can use the buttons to set the battery charging current, the AC/solar charger priority, and the permissible input voltage depending on the application.

Between a Low-Frequency Power Inverter and a High-frequency power inverter, which is Better?

The Low-frequency power inverter is clearly superior to the high-frequency power inverter. The following are some of the capabilities that make it the ideal option when choosing a power inverter;

The low-frequency inverter has a peak power of up to 300% and can maintain this level for many seconds. On the other hand, the high-frequency inverter can only manage to reach 200% and maintain this level for only a few seconds.

In terms of reliability, the high-frequency inverters depend on electronic switching and are therefore prone to failing, especially at high power levels.

The low-frequency power inverters are superior when it comes to reliability also total energy capacity. These power inverters can comfortably handle more power surges over an extended period.

Toroidal Transformer Power Inverter or Square Transformer Power Inverter, Which One Is Better?

The Toroidal transformer power inverter has a small size and a simple appearance. Electrical energy is reduced in these inverters, resulting in improved illumination and a more comprehensive range of light output. Energy-saving toroidal transformer inverters are widely used in a variety of sectors, including household appliances.

Toroidal Transformer And Square Transformer

It can also be used in medical, audio applications, and renewable energy. Our VSUN200 has a toroidal transformer power inverter.

The Square transformer power inverter has longer life time than the toroidal inverter normally. However, the toroidal transformer power inverter may be used both at home and in light industrial settings. They will also lower your operating costs as they are very cost-effective in terms of maintenance and running costs.

It is ideal for home and office use as it reduces smoke and noise emissions. It has also has more functional safety and cooling systems.

Square transformer power inverter has low frequency interference as wells as the Toroidal transformer power inverter. Hence both are suitable for their where frequency interference is discouraged.

When considering electrical efficiency, the Toroidal transformer power inverter is the ideal choice with up to 92% while Square transformer power inverter possesses efficiency rating of up to 84%.

However, since the EI square transformer has a lower capacity, many will still choose it if they have a restricted volume.

But when it comes to installation, the Toroidal power inverter is easier compared to the square transformer power inverter.

Low Frequency Pure Sine Wave Power Inverter

Just like the Toroidal transformer power inverters, the square transformer power inverter also has a long lifespan and can function normally even at 30 degrees Fahrenheit.

Comparatively, the toroidal transformer power inverter performance efficiency ranges between 90% to 92%. The efficiency of the square transformer power inverter ranges between 80% to 84%.

In terms of heat increase, the square transformer power inverter has a considerable temperature rise.

In terms of magnetic leakage, the toroidal transformer has a relatively low magnetic leakage compared to the square transformer, whose leakage is quite considerable. Therefore, the former has low-frequency interference.

You will be required to consider your total usage and their performance in order to choose the ideal inverter for your needs. Based on the above analysis, both transformer inverters have advantages and disadvantages, implying that you may utilize either where it is most appropriate.

How Can I Choose the Right Sizes of Pure Sine Wave Solar Power Inverter?

When choosing a pure sine wave solar power inverter, you must be keen on the inverter’s wattage. For the perfect inverter, its watts rating should approximately be equal to the watt rating of your solar system.

Basically, if the solar system has a watt rating of 2000 watts, you should use a solar with a rating of 2000 watts or probably a little more. However, excess watt ratings can lower efficiency.

The other factor you should consider is the surge watts. This is the amount of power your inverter can support within a very short period. The right inverter for your solar system should be almost equal or greater than the projected surge watts of every appliance or electronic device.

It is therefore vital to consider your total wattage when choosing the ideal pure sine wave solar power inverter.

Which are The General Safety Precautions When Using the Pure Sine Wave Power Inverter?

The following are the vital tips you should observe to avoid accidents and to damage the inverter;

To minimize the electronic shock and fire risk, ensure all wiring is professionally done using quality and recommended wires. Ensure you fix or replace any damaged wires.

The inverter should not be exposed to dust, spray, snow, or rain.

Avoid overheating by ensuring the inverter is installed in a well-ventilated location. We recommend you allow around 30cm of clearance around the inverter to enable airflow.

To avoid explosions or fire outbreaks, we advise you to ensure the inverter is far from flammable materials. Gasoline-powered machines and fuel tanks pose a major risk when in the space location with the inverter.

You may be exposed to electrical shock or fire if you disassemble the inverter.

During cleaning, you should first disconnect the AC and DC power from the Pure sine wave power inverter.
