Which Inverter is Right For You? High Frequency or a Low Frequency Inverter

great information.

High frequency inverters are typically smaller and lighter and offer a slightly better efficiency rating, but because they don't use an output transformer, they don't offer any galvanic isolation between their DC boost stage and their AC output, which makes high frequency inverters far less safe when powering household appliances. Lightweight high frequency inverters can even set your appliances on fire during a catastrophic failure of their H-Bridge circuit.
