Best 4000 Watt Inverter Generator: Buying Details

After knowing the best 4000-watt inverter generators you can buy, it’s time you understand the things you need to look for while making your choices. Here are some considerations to have on your fingertips while searching for the ideal inverter generator.

Power needs

Before you can even put the finger on a model, you have to consider your power requirements. Consider the number of appliances you need to power up and calculate their peak watts and the running watts. Add all the watts including the starting watts and see if the model you’re about to buy will run them all.

Fuel type

In most cases, a buyer will forget to check the fuel type. Inverter generators are either gas-powered, propane-powered or dual fuel. So, which fuel source do you have access to? Which of the three do you feel is ideal for you? If I were asked for advice, I would recommend the dual-fuel since it offers you the option for gas or propane.

Fuel Tank Capacity

Once you decide on which fuel to go with, it’s time you think of the fuel tank which applies to the gasoline model. The tank capacity will tell you how much fuel you need to carry during your next camping or RVing trip. So, if you need to power heavy loads, then you need an inverter generator with a moderate fuel tank which won’t require refilling all the time.

Runtime

And since I have given you best 4000-watt inverter generator models with high fuel efficiency, you need to look at the run time. For home emergency backup, you don’t need to go with the top run time. But if you are a camper or you want to power your RV, then you must pick a model with better run time.

Number of Outlets

Inverter generators come ready for use. However, some have limited outlets. A good generator needs to have at least four outlets. If you’re buying an inverter generator for your RV, then you must purchase an RV-ready model. That way, you can connect the RV directly without needing an adapter. Also, there needs to be an AC and DC outlet and perhaps a USB charging port. That allows you to have an easy time charging your phone or tablet, or such.

Noise Level

Yes, inverters are known to be quite silent in their operation. But not all inverter generators are quiet. Camping and RVing require low noise generator. For you to be sure you’re buying quite model, you will need to check at the decibel value of each model. Pick a model with less than 60dB.

Eco-Throttle

One of the reasons inverter generators are famous is the fact that they can adjust their engine speed automatically to produce enough power for a specific need. The ability to do that is the Eco-Throttle. If you need a model that is high on fuel efficiency and quite reliable, then buy a model that utilizes the technology.

Portability

Yes, don’t forget to check on the portability, especially if you will be using it for camping or RVing. The true portability and lightweight design will allow for easy transportation and storage. A portable model needs to feature handles for lifting or wheels and handle for pulling.

Frequently Asked Questions (FAQs)

Is it safe to use a 4000-watt inverter generator to run a TV?

Yes, as long as the generator has a low total harmonic distortion which allows it to provide safe power to sensitive electronics like a TV.

Will my 4000-watt inverter generator run my microwave?

Typically, a standard microwave will require around 1000 running watts. The best 4000-watt inverter generator with at least 3800 running watts and 4000 starting watts can run the microwave pretty well.

GLOBO TOOLS OVERVIEW

While making all your judgment to the products, remember to check on the warranty too. Also, follow your buying budget to ensure you buy a model within your limits. Every product on this list is ideal for home use, camping, and even RVing. So, don’t get stressed. If you’re still having selection problem, pick any model and proceed to buy. Good Luck!
