Best 3000 Watt Power Generators

3000 watt generators m3000 Watt power generators are very balanced units, offering strong and reliable power at acceptable cost and noise, from relatively compact units.

Unlike somewhat smaller and weaker 2000 Watt power generators, modern 3000 Watt power generators often come with features that were reserved for larger units just a few years ago.

Intro to 3000 Watt Power Generators

3000W power generators feature Running/Starting power in the 3000-4000W range - there is no clear margin between 2000W, 3000W, and 4000W generators, especially since some units have a large margin between their Starting and Running watts.

So, when looking for a good 3000W power generator, there are few things to consider first:

Fuel Type

Most 3000W power generators use either gas (gasoline) or dual-fuel gas/propane combination.

To help users with fueling their units, most of the 3000W power generators accept gas fuel with up to 10% ethanol.

However, gasoline with 10% ethanol is not the best fuel to store for a longer period of time, unlike propane which can be stored in propane tanks for a very long time.

Also, propane as a fuel is much cleaner for the environment, it is cheaper and prolongs the operating time of the generator.

On the other hand, when powered by propane, power generators lose some output power, usually around 10%.

Note: most power generators that are designed to use gas only, can be converted to use propane, too. However, if such conversion kits are not supported officially, they are NOT recommended.

3000W power generators that use diesel or natural gas are not very common.

Engine Starting

Call me lazy, but the electric start system is an excellent feature. 3000W power generators have engines small enough that can be more or less easily started manually, but it is much more convenient to start them with the press of the button.

And if the unit features an automatic choke, even better.

Some units also feature a remote control fob, allowing the user to start the power generator from the distance, usually up to 100-200 feet (30-60m).

Electric starting systems are based on the lead-acid 12V 5-10Ah (or sometimes slightly larger) batteries that are able to provide strong enough currents to crank the 150-250cc engines.

And when the engine starts, power generators automatically recharge their batteries.

Note: If the power generator is stored for a longer period of time, be sure to keep it in the cool area and that the battery is recharged every 1-2 months with a smart battery charger. Also, be sure to store the power generator as recommended by the manufacturer - read the Owner's Guide again, if necessary.

Physical Dimensions and Weight

The size of 3000W power generators varies, just as their output power and runtime vary.

But, they are still compact enough to be easily carried in cars, trucks, RVs, and similar vehicles.

Also, their dry weight (weight without the fuel) is mostly in the 90-150 pounds (~41-68 kg) range, allowing a single adult to transport the generator using the built-in wheels (if present) and allowing two adults to carry the power generator via built-in handles to shorter distances - just be aware of the total weight and be careful!

Note: some units don't feature transport wheels by default, but additional 2 or 4 wheel kits can be ordered later, when/if required. 

Running/Starting Watts

Running watts is the normal maximum output power of the generator while Stating watts is the maximum output power of the power generator for a short period of time.

Starting watts are important when the power generator is used to power units with electric motors and similar loads that require more power when starting - hence "Starting Watts".

Note: If your power generator is running very close to its maximum (Running) power, it is underpowered - consider getting a larger power generator or compatible Parallel Ready unit!

Parallel Ready

Parallel Ready 3000W power generators allow the user to connect two same power generators (or two compatible power generators) in parallel, practically doubling the output power.

Some power generators feature simple Parallel Ready cables, while other units feature Parallel Ready connection kits that also feature additional ports, usually RV and similar, high output power ports.

champion 100319 50amps paralel kitSome companies manufacture even several types of Parallel Kits with different receptacles, allowing the user to get the best fit possible for his/her needs.

Warranty

The warranty period for 3000W power generators is usually between 1 and 3 years, rarely up to 5 years. Also, it is not the same if the unit is intended for domestic/residential use or for commercial use.

However, some models come with the same residential/commercial warranty, showing that the company believes in the quality of their power generators - highly recommended, even if You don't plan on using the power generator commercially.

Note: warranty is void if the power generator is not used according to the manufacturer's instructions!

Receptacles

Most common receptacles include:

- AC 120V 20A 5-20R,

- AC 120V 30A L5-30R,

- AC 120V 30A TT-30R,

Note: 120/240V 50A (14-50R) and 120/240V 30A (L14-30R) ports are usually available only as part of the Parallel Kits.

- DC 12V Automotive (Cigarette Lighter Port),

- DC 12V battery charging port,

- USB ports: 5.0 volts, 5-9 volts, 1-4 Amps

Also, some units don't feature USB ports but come with a USB port adapter.

Obviously, not all power generators come with all these ports!

Price

The price of the 3000W power generators varies significantly, depending on the unit's features and specifications, output power, noise levels, output ports, safety features, etc.

The most expensive unit is not always the best one, but also, what you pay is usually what you get.

However, power generators, especially inverter power generators, are complex machines and as such, they are not cheap.

When looking for a new power generator, always choose according to your own needs and preferences.

Safety Features

Safety features usually include a low-oil engine shut-off system, an overload automatic circuit breaker, and power-ready indicator lights.

Additional safety features may include Carbon Monoxide (CO) sensor, which can be very helpful.

Note: Never operate any power generator in the closed areas since they emit very dangerous, colorless, and tasteless Carbon Monoxide. And no, opened garage door is NOT an open space!
