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.

  1. We are considering using solar to power a cooler of approximate 2 refrigeration tons capacity. Usage of cooler is approximately 8-12 hours a day. Could you estimate the solar system that can be used for this purpose in terms of solar panel size, battery with controller and inverter. Then please do inform us the estimated cost of the system.

    Thank you
