Low frequency inverters are a type of power inverters that operate at low frequencies, typically around 60 Hz. They are distinguished from high frequency inverters by the size of their transformers and the switching speed of their transistors.

These inverters are designed to convert DC power (Direct Current) into AC power (Alternating Current), which is used to run household items and electrical appliances. This makes them an essential component for anyone without access to a mains power source, as they can provide a plentiful amount of electricity.

Advantages of Low Frequency Inverters

Low frequency inverters have several advantages over their high frequency counterparts. They are designed to handle higher power spikes for longer periods, making them more robust and reliable. This capability is particularly important for devices like power tools, pumps, and appliances with electric motors that require high starting power. Low-frequency inverters can operate at peak power levels up to 300% of their nominal power level for several seconds, whereas high-frequency inverters can only operate at 200% power level for a fraction of a second.

Another advantage is their reliability. Low-frequency inverters operate using powerful transformers, which are more reliable and sturdy than the high-frequency inverter’s MOSFETs (Metal-Oxide-Semiconductor Field-Effect Transistors), which use electronic switching and are more prone to damage, particularly at high power levels.

Built-in Charger and Other Features

In addition to their robustness and reliability, low-frequency inverters come with a wide range of technical features and capabilities, including a built-in battery charger. This feature allows the inverter to charge a battery from an AC power source, such as a generator or shore power at an RV park, truck stop, or home.

Other features of low-frequency inverters include UPS (Uninterruptible Power Supply) functions, bypass mode with no battery connected, power saving mode, and various charge settings for different battery types and charging voltages.

Applications of Low Frequency Inverters

Low frequency inverters are designed for large off-grid power systems and are more suitably equipped for powering heavy appliances. They are typically used in power levels within the thousands, such as 2000W-3000W and above. They are ideal for powering various kitchen appliances, such as refrigerators, microwaves, dishwashers, ovens, and devices with electric motors like power tools, washing machines, vacuum cleaners, and air conditioners.

Despite their larger size and weight compared to high-frequency inverters, low-frequency inverters are a great investment for anyone with a lot of powerful electrical appliances in places with limited or no access to standard electricity. They can provide a reliable backup power solution and even completely replace conventional electricity with the same quality power supply.
