离网逆变器 is simple which convert the DC power stored within a battery (direct current, 12V, 24V或48V转换成交流电(交流电), 230-240V) that can be used to run your household items and electrical appliances, 从冰箱到电视机再到手机充电器. 逆变器s are an essential item for anyone without access to a mains power source, 因为它们可以很容易地提供充足的电力.
Low-frequency 逆变器s have the advantage over high-frequency 逆变器s in two fields: peak power capacity, 和可靠性. Low-frequency 逆变器s are designed to deal with higher power spikes for longer periods of time than high-frequency 逆变器s.
事实上, low-frequency 逆变器s can operate at the peak power level which is up to 300% of their nominal power level for several seconds, while high-frequency 逆变器s can operate at 200% power level for a small fraction of a second.
The second main difference is reliability: low-frequency 逆变器s operate using powerful transformers, which are more reliable and sturdy than the high-frequency 逆变器’s MOSFETs, 哪些使用电子开关，更容易损坏, 特别是在高功率水平.
除了这些品质, low-frequency 逆变器s come with a wide range of technical features and capabilities which most high-frequency 逆变器s lack.
