How to Choose the Best 3000-Watt Portable Generator 

The very first thing you should consider when choosing a portable generator is the device’s power. Is a 3000-watt generator enough to cover your power requirements? Check its starting and running watts.

The starting watts rating is crucial especially if the load will consist of several devices that draw a high amount of surge power when starting.

The running wattage is equally important too and should be able to sustain the wattage requirement of the appliances that you’d want to run together.

In addition to meeting your power requirements, check out the generator’s runtime. Regardless of what you plan to use your 3k watt inverter generator for, a longer runtime means that you won’t need to refuel often.

Lastly, consider a 3000-watt generator that offers the most convenient features within your budget. Here, consider the type and number of outlets available, type of starter, available circuit breakers, and gas and oil drain. In addition, check out the type of alerts that the control panel is endowed with, for instance, low oil and remaining runtime.

What Can You Run on a 3000-watt Generator? 

You can run any appliance on these generators provided the starting power and running power don’t exceed 3000-watts. For instance, for a quick breakfast fix, you could plug in the juicer or a coffee maker as you fry some eggs and later on plug in the dishwasher when nothing else needs powering.

It’s also possible to run several items and run them simultaneously. What’s important is to ensure that the total load is below 3000-watts. That’s to say that you can plug in 2 1500-watt appliances or up to 10 300-watt devices.

When adding a motor-powered appliance to an existing load, ensure that the available wattage capacity is enough for the motor’s starting power demand. For instance, if a generator is running 4 devices with a total running power of 2000 watts, you only have 1000 watts remaining. This means that you might not be able to add another appliance with, let’s say, 1500 starting watts even if the actual running power is 900w.

Here is a list of appliances that you can run on a 3000-watt generator:

Item Starting Power (w) Running Power (w)
10,000 BTU AC 2200 1500
3/4HP Furnace Fan 2350 875
Wet/Dry vacuum 2500 888
Miter Saw 2100 840
7 ¼’’ Circular Saw 3000 1500
Planer 2400 600
Electric Chainsaw 2400 1200
Circular Saw 2400 1200
Microwave 1000
Refrigerator 750
Portable Heater 1200
Sump Pump 1200 800
Water well pump 1000

Conclusion

There are some good reasons to choose an inverter generator. A 3000-watt portable inverter generator might be a great pick if you want power without compromising the portability aspect of the generator so much.

These generators are capable of running most household appliances (simultaneously or intermittently depending on starting and running power) and can also be used in construction sites as the table above affirms. They are also not so loud and most of them can be used in campgrounds and RVs.

If you haven’t yet decided on the best 3000-watt generator to buy and don’t mind the price, the Honda EU3000iS is worth checking out. Besides coming from a reputable brand, this generator is the most efficient and the quietest too.
