A low frequency inverter has several advantages but it is more expensive and because of the presence of massive iron core in its transformer it is also much bigger and heavier compared to its high frequency counterpart.
Often difficult loads that require high surge at the beginning, such as motors compressors or pumps are very well managed by low frequency inverter field effect stress and low frequency inverters can operate cooler in part due to the slower frequency of switching required to produce AC power.
In a high-frequency inverter there are almost twice the number of components compared to low frequency inverters nonetheless they are still smaller and lighter overall because of the absence of a large central transformer.
