Which is better? A “low frequency” & “high frequency” inverter?

Power inverter has two types: Low frequency and High-frequency power inverter.

off-grid inverter is simple which convert the DC power stored within a battery (direct current, 12V, 24V or 48V) into AC power (alternating current, 230-240V) that can be used to run your household items and electrical appliances, from fridges to televisions to mobile phone chargers. Inverters are an essential item for anyone without access to a mains power source, as they can easily provide a plentiful amount of electricity.

Low-frequency inverters have the advantage over high-frequency inverters in two fields: peak power capacity,  and reliability. Low-frequency inverters are designed to deal with higher power spikes for longer periods of time than high-frequency inverters.

In fact, low-frequency inverters can operate at the peak power level which is up to 300% of their nominal power level for several seconds, while high-frequency inverters can operate at 200% power level for a small fraction of a second.

The second main difference is reliability: low-frequency inverters operate using powerful transformers, which are more reliable and sturdy than the high-frequency inverter’s MOSFETs, which use electronic switching and more prone to damage, particularly at high power levels.

In addition to these qualities, low-frequency inverters come with a wide range of technical features and capabilities which most high-frequency inverters lack.
