Investing in a reliable generator is a must. Since you’ll be relying on this machine during outages, it’s just right that it stays functional for years. Also, sizing your generator to the amount of electricity you need will help find the best match to your household or commercial space.

There are tons of options out there but not every product is for the money. Since we’re looking for a high-power model, we need to be meticulous as extra power also means added price.

How much generator power do you need?

Again, we may sound like a broken record, but always size up the generator before buying it. Knowing how much power you need will save you thousands of dollars from buying a dysfunctional generator.

Basically, the amount of power you need will depend on the load you want to plug into the engine. Usually, home use will require lower power than those used for commercial establishments. Let us help you size up your generator for home use:

Most home appliances can run simultaneously at around 3,000 to 6,500 watts. For homes with city water supply and a small furnace, the basic needs for heating can be met at 3,000 watts. If these basic heating systems are larger, the required power doubles at 6,000 watts.

Remember, if you’re buying a portable generator never expect that it can run your entire household. You’re buying a generator not a power plant! Even if it’s the longest running portable generator, it will have operational limitations.

So is a 4,000-watt portable generator enough to cover the staples? If you’re just running a small heater and a few lights, this generator will be more than enough. But to make sure, here are some of the common household appliances and the generator power it requires to run:

As you see, you can run most household appliances with the best 4000 watt portable generator. Those that need higher starting and running watts should be run independently or together with a low-watt appliance. The likes of lights, laptop, TV, and less power-hungry gadgets can be plugged in simultaneously.

Be careful with the amount of load you’ll connect to the generator to avoid overloading and quick fuel burns. As a rule of thumb, around 70%-80% of load is the safest range to keep your generator running smoothly and in longer periods.

Commercial vs. home generators

After you’ve identified the load you want to plug into the generator, it’s time to know the difference between a commercial and a household generator.

First off, commercial generators are massive and way powerful too so it can run a business until the power supply comes back. This isn’t a portable type although some establishments can have portable units to power up individual sections of the business.

Commercial generators are three-phase generators. This means the engine is geared to power large and energy-hungry motors.

Typically, three-phase generators are used for industrial purposes and considered as the longest running portable generator.

On the other hand, household generators are scaled-down versions with around 2kW to 7kW power. These generators are way smaller, cheaper, and quieter than commercial generators. Household generators can’t be used for massive commercial use. But for homes that need to run with power during outages, commercial-grade generators can be installed. However, this can cost a fortune considering that outages don’t happen every day.

Types of generator

For household use, there are three major types of generators you can choose from: home standby, portable, and inverter. Nowadays, there are hybrid types that combine the features of any of the three types.

Standby home

If you want a generator that turns on automatically during a power outage, you can avail a standby home generator. This is installed outside the house and fixed permanently. This runs on propane or natural gas so there’s no need to monitor the fuel levels for refilling.

Standby generators are the best options for homes experiencing frequent outages. If you need your appliances running continuously for medical and security reasons, a standby generator is a must-have.

The cost of standby generators can range from $2,000 to $20,000 depending on the size and power capacity.

Portable

Portable generators, on the other hand, are the most popular. These are typically compact, lightweight, and easy to transport. Portable generators are usually run by gasoline and have to be refilled multiple times a day, more so if it’s running with a high load level. Also, the longest running portable generator can be pricey.

There are power outlets on the controls of the generator so you can plug appliances or extension cords directly to the engine. A portable generator typically has an alternator, internal combustion engine, fuel tank, starter, and outlets. This type ranges from $500 to $2,500 with different wattages.

Inverter

Inverter generators are known to be the quietest type without sacrificing the wattage capacity. Somehow, inverter generators work the same way as other types. However, after the raw AC power is produced, an inverter generator converts this into DC power and then into AC once again. This process is known to produce cleaner, more stable, and smooth power source.

Inverter generators have the basic portable generator components but with the addition of a microprocessor that allows the conversion of the current from AC to DC and then back to AC.

Aside from this, inverter generators are also engineered to have sound attenuating chassis. This is why inverter generators are quieter than other types. Most inverter generators share the same price range with that of portable types.

What to choose based on the situation

All of these generator types are useful, but the best one depends on the situation. Where are you going to use it? How much noise can you tolerate? Do you have the budget for it? Here, we listed some of the possible scenarios and the best generator type to choose

1. I always experience frequent power outages

This situation is frustrating and directly impacts your quality of life. When prolonged outages are taking place, it’s best to get any of these three: large inverter, portable, or stand-by.

The best choice is a standby generator in case you’re in the middle of a blizzard or a snow storm. Running a generator manually outdoors in this weather condition is dangerous and a big hassle. When it comes to portable models, look for the one with the most juice. The best 4000 watt portable generator we reviewed below would be a perfect choice.

2. I rarely experience power outages at home

On the flipside, if you rarely encounter power outages, you’re better off with small portable inverter generators.

Small inverter generators with a power of around 2kW will be excellent in running lights and heating systems one at a time. During a brief outage, this should be enough to sustain your need for electricity. This generator type is also called recreational generators as it can fit on a car trunk for camping and outdoor use.

3. I only experience outages once in a while

Casual outages don’t call for expensive stand-by generators. You’ll likely survive with a high-power inverter engine like the ones we reviewed below. There’s a chance that these outages can happen in extended periods so you need that extra kick to run appliances.

Always consider the purpose of the generator before buying one. This way, you can size it up and maximize its full potential. There’s nothing wrong in investing in expensive and the best 4000 watt portable generator if you have the money. Just make sure that you run it once in a while to keep the engine in check.

What first-time buyers should consider

Aside from the first points discussed, there other factors to consider before purchasing a generator for home use. This is to ensure that the generator will function optimally. Here are some points to ponder:

⚡Location of use

Are you living in a high-altitude area? If so, you need to de-rate your generator requirement by 1% for every 100 meters above sea level.

Aside from that, remember that you’re not supposed to operate a generator close to your house. These engines produce harmful fumes including the deadly carbon monoxide. Make sure that you have enough space to cover the capacity of the generator.

Also, check if your location is hotter than usual as this can affect the performance of the generator. Consider this before getting a longest running portable generator.

⚡Maintenance

When you’re planning to purchase a certain model, take time to check if there are available replacement parts in case repairs would be needed. The brand should also provide the replacement parts to ensure compatibility. If not, the generator should have readily available parts in the market.

⚡Running conditions

Never run your generator at a load of more than 80%. On the other hand, never use the generator for a load of 40% or lower as this can damage the engine. Always watch out for overloading as this can cause money due to faster gasoline use.

⚡The size and weight of the generator

Most of the time, the size and weight of the generator aren’t defining factors. But for small homes, getting a compact and light generator will be suitable than investing in a larger one. Take note that some people purchase generators for camping purposes only. This will only need small and hand-carry generators.

⚡Noise level

Who wants a noisy generator? If you want a quieter option, always stick to inverter models. These are made to have low noise levels around 45-60 dBA (A-weighted decibels). This way, your neighbors won’t complain about the noise and you get to reduce the wear and tear on the generator.

Even though inverter generators are quiet, it’s still not safe to place it too close to your house. Since it’s still powered by gas, the fumes can pose health threats to your family.

⚡Runtime

It’s always best to get the longest running portable generator to sustain your electricity needs. Most portable and inverter generators can run for up to 9 hours in a 50% load. Meanwhile, large loads will slash the run time drastically. If you think you’re going to experience extended power outages, you might as well invest in a generator with a larger gas tank.

The longer the run time the better for you. However, this will come with additional dollars as well.

Should I choose a 4,000-watt generator?

If you need more power, the best 4000 watt portable generator is for you. With this, you can run more appliances at a time, thus enjoying comfort even during an extended power outage. A 4,000-watt generator also has a larger fuel tank which allows it to run longer than other models. If you can, opt for an inverter type so your home will be supplied with clean and stable electricity.

However, the only downside to this powerful generator is that it comes with a hefty price tag. Not all households can shell out thousands of dollars just to acquire a generator. Still, nothing beats preparedness when power outages strike.
