If you live in an area prone to power outages, an inverter generator might be a worthwhile investment. Inverter generators are designed to provide clean, stable power that can safely run sensitive electronics like computers and medical equipment.

The average American experiences 1,300 minutes of power outage per year, which is equivalent to about 22 hours. This can be especially frustrating if you have a family or rely on certain appliances to stay safe and healthy.

Inverter generators can provide power for up to 10 hours on a single tank of gas, making them a reliable option for extended outages. This can be a lifesaver if you live in an area with frequent power outages.

What is an Inverter Generator?

An inverter generator is a type of portable generator that converts fuel into electricity, producing clean and stable power similar to what you get from your home outlets.

It works in three stages: generating alternating current (AC) electricity, converting it into direct current (DC), and inverting it back to AC. This process results in a consistent electrical current safe for sensitive electronics like laptops and smartphones.

Inverter generators are typically more compact and quieter than traditional generators, making them ideal for camping, tailgating, and use in residential areas. They run on various fuels, including gasoline, diesel, or propane, offering flexibility for different needs and preferences.

Here are some key features of inverter generators:

What Is an Inverter?

An inverter is a crucial component of an inverter generator. It's responsible for converting the alternating current (AC) electricity generated by the generator into direct current (DC), and then inverting it back to AC.

This process is essential for producing clean and stable power that's safe for sensitive electronics. Inverter generators typically produce power in three stages: generating AC electricity, converting it to DC, and then inverting it back to AC.

The inverter stage is where the magic happens, allowing the generator to produce power that's consistent and reliable. This is especially important for electronics that require a stable power source, like laptops and smartphones.

Here's a quick rundown of the inverter process:

  1. Generates AC electricity
  2. Converts it to DC
  3. Inverts it back to AC

This process results in a consistent electrical current that's safe for sensitive electronics.

Introduction

Credit: youtube.com, What is an inverter generator? (How does it work?)

An inverter generator is a type of portable generator that produces AC power, like a conventional generator, but converts it into DC and back into AC power using electronic circuitry.

This process makes the output of an inverter generator more stable and reliable than a conventional generator.

Inverter generators produce cleaner and more stable AC power with less distortion, which means less variability in the power supply.

They also have less voltage fluctuations and noise compared to conventional generators.

This is because inverter generators use clever electronic circuitry to convert the power, resulting in a smoother and more consistent output.

Benefits of Generators

Inverter generators are a game-changer for outdoor enthusiasts and those in need of a reliable backup power source.

They're designed to be much quieter than traditional portable generators, with some models producing as little as 53dB(a) of noise. Most regular portable generators start at a noise level of 68dB(a) and can increase to 75 to 85 dBA or more.

Inverter generators use special mufflers and sound-dampening technology to reduce noise pollution. This makes them perfect for RVing, camping, and tailgating, where noise levels can be a major concern.

Inverter generators are also more efficient than traditional portable generators. They adjust their engine speeds to fit the output required, which saves fuel and reduces noise pollution.

For example, a 4500-Watt Inverter rated at 4500 Starting watts and a 4000 Running watt capacity can provide clean power to your sensitive electronics. This is because inverter generators have a very clean signal that never varies, with some manufacturers touting less than 3% Total Harmonic Distortion (THD).

Inverter generators are also more environmentally friendly, producing fewer emissions than traditional portable generators. This makes them a great option for those who want to reduce their carbon footprint.

Here are some key benefits of inverter generators:

  1. Clean Energy: Inverter generators produce stable and clean power, which is safe for sensitive electronics.
  2. Quiet Operation: They operate more quietly than traditional generators, making them less disruptive in peaceful outdoor settings or residential areas.
  3. Fuel Efficiency: These generators adjust the engine speed to match the power demand, leading to better fuel efficiency and longer run times.
  4. Portability: Most inverter generators are compact and lightweight, making them easy to transport and store.
  5. Lower Emissions: They often produce fewer emissions, making them a more environmentally friendly choice.

Choosing and Using a Generator

Inverter generators are a great choice for outdoor activities, camping trips, and even home backup power. They're designed to be more efficient and quieter than conventional generators.

For camping or powering small appliances, a generator with 1,000 to 2,000 watts is usually sufficient. This can power a large laptop, which typically uses around 100 watts of power.

To choose the right size, list the devices you plan to run simultaneously and tally their wattage requirements. Always choose a model with a slightly higher capacity than your calculated need to ensure reliability and longevity.

Inverter generators produce a stable and clean output waveform, making them ideal for powering sensitive electronic devices and appliances without causing damage or interference. They're also generally quieter than conventional generators, making them ideal for residential areas and outdoor events.

How Generators Work

Generators convert rotating mechanical energy into electrical energy. They use an engine, typically running on gasoline, diesel, propane, or natural gas, to turn an alternator which produces alternating electrical current or AC.

The utility company supplies Alternating Current (AC) to homes and businesses. This is the same type of current that a portable generator can produce.

A Power Inverter produces Alternating Current from Direct Current (DC) using electronics. It draws power from a power source such as a car battery or solar panel.

Portable inverter Generators combine the two principles. They generate a variable frequency alternating current that changes with the engine speed.

A higher engine speed results in a higher frequency, which means the generator is producing more current. A lower engine speed equals less current.

The generator's inverter circuit inverts the DC into an unvarying 60 hertz AC current that is free from glitches, spikes, and surges. This makes it safe for electronic devices and other sensitive equipment.

The engine speed of a portable inverter generator varies to produce the power required. Turn on a few lights and the engine speed increases. Turn them off again and the engine slows down.

Some portable inverters have engine speed set points. They run at a fixed speed for any power need up to a maximum before their speed increases to the next set point.

Choosing a Generator Size

A 1,000 to 2,000 watt generator is suitable for camping or powering small appliances. This size is perfect for running a large laptop, which uses around 100 watts of power.

To calculate your generator size needs, list the devices you plan to run simultaneously and tally their wattage requirements. For example, a refrigerator uses 300-400 watts of power, so if you need to power one, a 3,000 to 4,000 watt generator may be necessary.

A good rule of thumb is to choose a model with a slightly higher capacity than your calculated need to ensure reliability and longevity. This will give you some extra power in case you need it, and will also help extend the life of your generator.

Here's a rough guide to help you choose the right generator size:

Keep in mind that starting motors require up to 6 times the power to start versus the power required to run. So, be sure to check the starting watts of your generator to ensure it can handle the power requirements of your devices.
