What Size Generator for My RV 30 Amp and 50 Amp Options

The good ol’ conventional generators are quite useful for emergencies – powering up essential electrical devices during complete blackouts and outages. In fact, the generator market is at unbelievable heights, and you know what? It’s continuously rising.

While all of this sounds incredible, generators can sometimes be annoying. The hefty repair and maintenance, terrible noise, and danger to electrical devices make it a little inconvenient and less viable option.

But don’t you worry. There’s something new in the market that provides you with the utmost value. We are talking about INVERTER GENERATORS. Sounds fancy, right? Read along as we break down each and every aspect that you must know about them.

What is an Inverter Generator?

An inverter generator has a different mechanics process compared to its counterparts. It produces a continuous rhythmic flow of current, preventing any frequent ups and downs of volt that may destroy your electrical devices.

Nowadays, the current electrical devices such as mobile phones, laptops, microwaves, and bulbs are not too resistive to power surges, leading to their breakdown. All your devices will remain intact and protected from power surges with an inverter generator.

Let’s dig a little more deeply into the working mechanics of an inverter generator.

How does an Inverter Generator Work?

As a layperson, it’s not easy to understand the complete mechanics of a generator. Therefore, we have tried to explain the process and highlight the differences in the most simplified way.

Before we proceed, you must know that inverter generators produce power that is clean in a three-step process. Firstly, it converts the AC current into DC power, smoothing out all the disturbance and volatile frequencies.

Now, it inverts the DC power into AC power again, which is clean and operates in a pure sine wave structure, i.e., without any disturbance and noise. In contrast, the conventional generator runs on AC current, which has high spikes, increasing the risk of damage to electrical gadgets.

The high frequency is due to a high % of THD (Total Harmonic Distortion), which causes the variance from the standard 120 Volts. Most inverter generators resolve this issue by operating at a THD of less than 6%, ensuring a consistent energy flow.

Prominent Distinctions Between Inverters and Generators

Till now, you must have got a little hang of the working process of inverters. Here we will look at some more of their properties to help you clarify their usefulness and functionality.

Noise Level

With inverters, you can be sure of one thing: they operate quietly. Most of them range between 50-65 decibels (dB) which is similar to the noise of a normal person conversation. Inverters can adjust their speed and power according to the load demanded.

Hence, they will operate slowly and quietly when a machine needs a low load. Plus, inverters that have a low % of THD makes them operate at a constant current flow, preventing surges and heavy noise. Moreover, there are special mufflers in mufflers, reducing noise to a great extent.

On the other hand, generators produce noise due to fuel combustion and gear rotations. The noise rises as you raise the rotor speed, which can be too audible in some circumstances.

With inverters, you can now rest peacefully, which wouldn’t have been possible in the presence of a traditional generator and its terrible loud noise.

Fuel Efficiency

With inverters, you’ll save on fuel costs. They will use fuel as needed since they adjust their speed and modify it according to the power demand. So, if you operate only a single bulb, the inverter will use little current and operate slowly to power the bulb.

On the other hand, if you decide to use a 500 W appliance, the inverter will adjust its power and fuel consumption as per the requirements. Hence, you’ll definitely save on your fuel, which can be costly sometimes.

In contrast, you can never expect a generator to be fuel-efficient. Suppose you have a generator with a 1000 W rated output, and it operates at an engine speed of 3600 RPM. Whether you want to light a 5W bulb or operate a 700W toaster, the generator will continuously run at 3600 RPM.

Hence, there will be wastage because fuel will be consumed even if you aren’t consuming anything.


Indeed, most inverters are portable generators. You can even find inverters weighing less than 30 pounds, i.e., light enough to carry it for any of your adventures. They are compact devices equipped with user-friendly handles, and their superior portability makes it possible to tuck them in any bag for camping trips or tailgating.

Despite being lightweight, most of them can provide ample power, allowing you to operate most of your devices. Be it any picnic or fishing adventure you’re planning to go to, packing a nice compact inverter should be top on your list.

With inverters, you’ll never have empty charges or be left stranded in emergencies.

Parallel Capability

You can even expand your generator to get more power output. Using a parallel cable, you can connect two similar inverters to power large appliances such as refrigerators, air-conditioners, or televisions.

Even if you have a low power inverter, don’t worry. With parallel capability, you can always have the chance to increase the power output and operate as many devices as you like.

Limited Power

Inverters fail to compete with their counterpart in this criteria. Most inverters have a max power rating of 7000 W, which is huge but not enough to last for a power outage.

On the other hand, generators can go up to 17000 W, suitable enough to power your entire home.

Top Three Best Inverters to Take Care of Electricity Needs

The unique abilities of inverter generators mentioned above are definitely useful. But when it comes to purchasing appliances, especially inverters/generators, most people proceed carefully due to the high investment involved. They have questions running all over their mind, making them doubt their purchase decision.

  • “Would it even work and not live up to its expectations?”
  • “What if it stops working after a while?”
  • “Are there any guarantees about the brand?”
