Heavy Duty Low Frequency Transformer Based Inverters VS Lightweight High Frequency, Transformerless Inverters.
High frequency, transformerless inverter technology has existed on the market for over two decades. It was originally developed by the Chinese as a cheaper alternative to US made transformer based inverter designs. By eliminating the iron core, copper wound output transformer these Chinese engineers suceeded in reducing the weight of which in turn substatially lowered both the shipping and manufacturing cost of these inferior inverters. Unfortunately for the consumer, the removal of the output transformer resulted in a much shorter life expectancy and a far poorer surge capacity for these lightweight inverters. In addition, without an output transformer to provide galvanic isolation between ththe inverter's DC boost stage and its AC output, these inverters pose the risk of not only damaging your home's applaiances, but can even set those appliances on fire when their MOSFET transistors fail.
Low frequency, transformer based inverters on the other hand, offer a much longer life expectancy (10 to 15 years), and a much higher surge capacity (300%+) for starting those difficult to start loads such as microwave ovens, water pumps, refrigerator freezers, washers and dryers, air compressors, and air conditioning units. Additionally, because low frequency inverters do incorporate an output transformer in their design, they do provide galvanic isolation to protect your appliances from the damage that can be caused by cheap high frequency inverter designs.
“Low-frequency, transformer-based inverters offer a far longer life expectancy and a much higher surge capacity than low-cost, high-frequency, transformerless inverters, and are a far safer choice for powering your home's appliances. That's why all American inverter manufacturers only use high-reliability, low, frequency, transformer-based inverter technology.”
When it comes to off-grid and backup power systems, the choice between low-frequency transformer-based inverters and high-frequency transformerless inverters can significantly impact performance, reliability, and longevity. While both have their advantages, low-frequency inverters stand out for their rugged durability, superior surge capacity, and reliability in demanding applications.If you need an inverter that can handle heavy-duty loads, extreme conditions, and long-term reliability, a low-frequency, transformer-based inverter is the best choice. While high-frequency inverters are lighter and more affordable for small, low-power applications, they simply can’t match the performance, durability, and surge handling of a transformer-based design.
