If you want to know the difference between an inverter and a generator, you’ve come to the right place.

In this article, I’ll discuss the pros and cons of each so that you can make an informed decision about which is right for you.

There are two types of generators, there are petrol/diesel generators and solar generators.

In this article, I’ll discuss the difference between diesel generators and inverters. I’ll also break down the differences between the storage, energy, weight and maintenance of each.

What is a Diesel-run Generator (DG)?

A diesel-run generator is a machine that uses diesel fuel to generate electricity.

Diesel generators are typically used as backup power sources in commercial and industrial applications.

Storage

Unlike a solar generator, a diesel generator does not store electricity. You pour diesel fuel into the tank, and the generator uses that fuel to power the generator.

Diesel generators are typically used as backup power sources in commercial and industrial applications.

This means that they are not intended to be used as the primary source of power, but rather as a backup in case of an outage.

Like most generators there is a bit of a time lag between start up and full power, but once the DG is running it will maintain a consistent output.

Output/Energy

Diesel generators typically have a higher output than inverters. This is because they are designed to power large commercial and industrial applications.

They are mechanical devices that convert the energy in diesel fuel into electricity.

Diesel generators are typically used as backup power sources in commercial and industrial applications.

This means that they are not intended to be used as the primary source of power, but rather as a backup in case of an outage.

Weight

Typically diesel generators tend to be on the bulky side and can weigh over 1000 pounds.

They need to be heavy duty casing and a separate diesel motor to generate electricity which makes them bulky.

Some have additional frames or even transport wheels to make them easier to move.

Maintenance

Diesel generators require regular maintenance and tune-ups. They also need to be run regularly to keep the engine in good condition.

This consists of oil changes, lubricant changes, and air filter changes.

Diesel generators should be run for at least 2 hours every month to make sure the engine is properly lubricated and to prevent corrosion.

What is an Inverter?

An inverter is a machine that converts DC (direct current) electricity into AC (alternating current) electricity.

Inverters are typically used in applications where AC power is not available, such as RVs, boats, and off-grid solar systems.

Storage

Despite popular belief, an inverter also does not store electricity.

Inverters take the DC power from batteries and convert it into AC power. This means that the inverter needs batteries to function.

Batteries store the electricity, so if you want your inverter to have backup power, you’ll need to have batteries connected to it.

Energy

The output of an inverter is typically lower than a diesel generator.

This is because inverters are designed to power smaller loads, such as RVs, boats, and off-grid solar systems.

Inverter generators are more efficient than other types of generators, even if they generate less power. The AC power generated by an inverter is “cleaner” than the power produced by a petrol or diesel generator.

Weight

Inverters are much lighter than diesel generators, typically weighing less than 100 pounds.

This is because they are smaller and do not have an engine.

Inverters are typically portable, making them easy to move from one location to another.

Maintenance

Inverters require very little maintenance.

The only thing you need to do is keep the batteries charged and replaced as needed. You also need to ensure that the distilled water level in the batteries is maintained.

Inverters do not require tune-ups or regular maintenance like diesel generators.

Inverter vs Generator: In Use

A inverter uses a range of switches and rectifiers to generate an alternating current from a direct current. The switches in the inverter allow it to work with different voltages and frequencies.

A generator, on the other hand, uses a mechanical process to generate electricity.

The engine in a generator turns a magnet inside of a coil of wire to create an electric current. This current is then sent through a rectifier to convert it into DC power.

The engine in a generator must be running to generate electricity, whereas an inverter can generate electricity even when the engine is off. This makes an inverter a more efficient choice for powering small loads.

Inverter vs Generator: Which Is Quieter?

How much noise a machine makes can be important in some situations. If you’re using a generator to power a construction site, the noise might not be an issue.

But if you’re using a generator to power a campsite or outside party, the noise level can be important.

Diesel generators tend to be very noisy, while inverters are much quieter.

The engine in a diesel generator is what makes the most noise, so if you’re looking for a quiet machine, an inverter is the way to go.

Inverter vs. Generator: What’s the Difference in Cost?

Even though generators are much noisier and use more fuel, they tend to be cheaper than inverters.

This is because generators are mass-produced, while inverters are still a relatively new technology.

As inverters become more popular, the price will likely come down. But for now, generators are the more affordable option.

The high cost of inverters is due to their quiet operation, compact design, and other characteristics. Even the cheapest inverters are somewhat more costly than generators. The expense is well worth it, though.
