Best generators with low thd Reviews & Top Picks

The most important consideration, especially for those who rely on sensitive electronics like laptops and cell phones, is to select a generator with low Total Harmonic Distortion (THD) to ensure safe operation.

Low THD generators use advanced inverter technology, which uses advanced algorithms to produce a clean and stable power output with minimal harmonic distortion. This makes them suitable for powering sensitive electronic equipment such as computers, audio equipment, medical equipment, and other electronic devices.

Low THD generators come in various types, including portable, standby, and inverter generators. Portable generators are designed for use on the go, while Standby generators are intended for use as a permanent power supply for a home or business. Inverter generators are typically smaller and more lightweight than other types of generators, making them ideal for camping, tailgating, and other outdoor activities.

Low THD generators typically come with additional features such as low oil shut-off sensors, automatic voltage regulation systems, and fuel shut-off valves. These features make the generator more efficient and safer to use. Additionally, it's important to consider the noise level, weight, and runtime of the generator when choosing a generator with low THD.

In summary, generators with low THD are generators that produce clean and stable power output with minimal harmonic distortion making them suitable for powering sensitive electronic equipment, come in various types and equipped with additional features such as low oil shut-off sensors, automatic voltage regulation systems and fuel shut-off valves.

Different generators have varying levels of Total Harmonic Distortion (THD). THD measures the distortion caused by the generator's amplifier. If you are using sensitive electronics, it's important to choose a generator with a low THD, as it will produce higher-quality electricity.

Generators with high levels of Total Harmonic Distortion (THD) can potentially harm delicate electronics such as plasma TVs, computers, and newer HVAC systems. As more households rely on these types of devices on a daily basis, manufacturers are increasingly producing generators with low THD to ensure safe operation of these electronics.

1. Honda EU2200i

The Honda EU2200i is an ideal portable generator for a variety of settings, including suburban homes, camping trips, and events where outdoor power is needed but noise is not welcome. It boasts a compact design, with a weight of less than 50 lbs, and produces little noise while operating.

One of the key features of this generator is its low THD levels, coming in at under 6%. This is crucial for powering sensitive electronics such as plasma TVs, computers, and modern HVAC systems without causing damage.

In addition, the EU2200i is designed for easy transportation, fitting in tight spaces and featuring a vent on the gas cap that can be closed to prevent fumes from escaping. It also has safety features such as a “low oil” alert, “fuel shutoff”, and automatic shut down for dangerous carbon monoxide levels.

The generator also has parallel capacity, allowing it to connect to another EU2200i for additional power, and can be controlled through a smartphone app, which provides maintenance reminders, operation monitoring, and wireless stop functionality.

With a maximum output of 120 volts, the EU2200i can power your HVAC system, refrigerator, and microwave, and charge electronic devices, but it's best to limit overall power usage. It can run for about 8 hours on a single fuel tank, and though it may cost more than other generators, it's a wise investment for its compactness, safety, durability, and clean power.

2. Westinghouse WGen12000DF

The Westinghouse WGen1200DF generator is suitable for large households that consume a lot of electricity daily. It can operate using either gas or propane and can run for up to 11 hours on a single fuel tank. This model is equipped with a remote start feature, so you don't have to get out of bed to turn it on.

With a maximum output of 240 volts, it can easily power all of your household appliances, including your entertainment devices, without the need to conserve energy. The WGen1200DF has low THD levels of less than 5%, making it safe to use for even the most sensitive electronics.

The generator does not come with an ST Switch, but it does have an ST Switch outlet, which allows you to connect it to your breaker box via a transfer switch for automatic power switching. Additionally, you can use a GenerLink if it is permitted by your electrical provider.

The WGen1200DF is quite bulky and weighs over 300 pounds, making it difficult to transport. It does have handles and a tough exterior for rough terrain, but its weight limits its portability. It is suitable for areas with inclement weather conditions, but keep in mind that running it in areas with abundant foliage can be a fire hazard. The generator produces noise levels of around 74 dBA, which is relatively quiet compared to other generators with similar power capabilities, but may still disturb your neighbors in a suburban setting

3. Generac XT8000EFI

The Generac XT8000EFI generator is designed with "True Power Technology," which reduces THD to less than 5%, making it safe to power even the most sensitive electronics. Its efficiency is further enhanced by features such as low oil shutdown and protected outlets that safeguard the machine from damage. With a weight of 216 pounds, it is relatively easy to move and store thanks to its 10" wheels and fold-down locking handle. One of its most notable features is the fuel injection technology that eliminates the need for a carburetor, resulting in more efficient fuel usage and fewer emissions. The generator also has idle control that conserves fuel, allowing it to run for up to 9.5 hours on a single tank. Additionally, a data panel monitors the machine's status, enabling users to keep track of its power load and maintenance needs. However, it should be noted that it may be quite loud, so it may not be suitable for residential use. The price is reasonable at $1,149.

    What is Total Harmonic Distortion (THD) in generators?
    THD is a measure of how much the shape of the waveform of the generator's output voltage deviates from a pure sine wave. A low THD rating means that the generator produces a cleaner, more stable power output with minimal harmonic distortion.

    Why is low THD important in generators?
    Low THD generators are suitable for powering sensitive electronic equipment such as computers, audio equipment, medical equipment, and other electronic devices. Harmonic distortion can cause power supply problems, and damage to the equipment.

    What types of generators have low THD?
    Low THD generators come in various types, including portable, standby, and inverter generators. Portable generators are designed for use on the go, while standby generators are intended for use as a permanent power supply for a home or business. Inverter generators are typically smaller and more lightweight than other types of generators, making them ideal for camping, tailgating, and other outdoor activities.

    What additional features do low THD generators have?
    Low THD generators typically come with additional features such as low oil shut-off sensors, automatic voltage regulation systems, and fuel shut-off valves. These features make the generator more efficient and safer to use.

    What should I consider when choosing a generator with low THD?
    When choosing a generator with low THD, it's important to consider the noise level, weight, and runtime of the generator, as well as its power output and additional features. Make sure to choose a generator that meets your power needs, and that is equipped with the necessary safety features.

When searching for a portable generator that is safe for your sensitive electronics, it's essential to look for one with low THD (total harmonic distortion). A THD level of 6% or lower is ideal for protecting devices like computers, plasma TVs, and HVAC systems from damage. Standard generators typically have THD levels between 9%-15%, which may be sufficient for powering lights and tools, but not for sensitive electronics. Be aware that many manufacturers do not advertise their generator's THD levels, so if you don't see any information on THD, it's safe to assume the generator may not be suitable for your needs
