5 Things to Consider when Choosing a Portable Generator ...

Portable power is necessary on many job sites often beginning with the job site trailer that gets set up even before the company stages the equipment. That unit will power the trailer anywhere from one week to one year depending on how long it takes to set up utility power. Tools, pumps, cranes, concrete mixing, and aggregate equipment are some of the most popular items run by large generators.

You will get efficient and thoughtful service from Dingbo.

When choosing a generator (or generators) for your job site, there are five criteria you should keep in mind.

1. Power output

Of course, the biggest consideration when choosing a generator is power output. Simply add up your total electrical power needs in amperage and voltages as a starting base. Consider what tools or equipment the generators will power to determine total power. How many of those will be drawing power from the generator at the same time? You need a generator with a peak power output greater than your total power load (the total energy of all powered tools and equipment).

&#;You also have to consider whether there will be any motor starting, because starting the motor on a machine takes twice as much energy as running steadily,&#; says Travis George, Product Manager, Doosan Portable Power&#;a manufacturer of 10 diesel-powered generators in the 25 kVa to 570 kVa (kilo volt-amperes) range with the smallest unit being the same size as a golf cart and the largest Ione being the same size as a pickup truck. &#;When working with a conveyor or rock crusher, for example, you need to take the motor data plate information when choosing a generator to ensure it has sufficient power for motor starting.&#;

And, once you&#;ve established the total running power requirements, find a generator that can provide 20 to 30 percent more power than that because, according to George, generators work best when they are working at 70 to 80 percent load. &#;Loads lower than that don&#;t allow the engine to burn as clean and the end-user doesn&#;t want to pay for something oversized. Bigger isn&#;t better; find the smallest generator that meets all of your specs.&#;

2. Connection compatibility

Also, if you will be running multiple tools, the generator will need not only enough power but also enough connections for those tools or equipment to plug into. You also have to ensure the generator has the type of connections that are compatible with your tools and equipment.

Most generators offer multiple connections and connection types for powering common equipment. Common types of connections include:

  • Standard 20-amp duplex receptacles - the same kind found in a house)
  • 30-amp twist-lock receptacles - compatible with cables used in the rental industry to accommodate electrical distribution gear or spider boxes.
  • Quick-connect Camlock connectors - which are rated for 400 amps and are popular in the rental industry
  • Electrical lugs - identical to connections on a circuit breaker, these are the connections with which an electrician will connect.

Additionally, there are also different voltages available: a 120/240 V single-phase, a 120/208 V three-phase, and a 277/480 V three-phase. Unique to the Canadian market, Doosan is the only manufacturer of portable generators that make a quad voltage, which includes 600 V on the job site and provides efficient power distribution. Doosan also provides the required CSA listings and TSA fuel tank containment and fuel tank breathing requirements for Canada.

3. Size

The more power you need, the larger the generator will be. Is there sufficient room for the generator? Are there any job site-influenced size restrictions? Does the generator need to fit through a door, for example? Do you have the means to easily pick it up and move it to another location? How many times will it need to be moved on a single job site? Perhaps getting multiple smaller generators will be easier to place and move than one single one.

Again, understanding when and where and how much power is needed will lead to better decisions.

4. Power input

Finally, generators provide portable power, but they also need to be powered. Options include diesel, gasoline, propane, and rechargeable battery. Battery-powered storage devices have a wire from which they can draw power, so they can only be used on-sites either hooked into the electrical grid or with solar power. All the other options will need to be refueled periodically, in which case it makes sense to use the same fuel you use for other equipment that is on-site. If you have diesel-powered machines on-site, for example, you will already have either a stock of diesel fuel on-site or a fuel delivery service, so it makes sense to use a diesel generator.

5. Rent or own

For how much time do you require portable power? If you need a generator for only a few days, renting it will be the better option. Once renting costs begin to compete with purchase costs, owing becomes the better.

&#;The larger the generator, the more likely it is to be a rental unit,&#; says George.

Also, when renting, you don&#;t have to worry about generator repairs and maintenance; if something goes wrong with your rented generator, the rental dealer will provide a replacement.

The Most Complete Generator Buying Guide for Businesses

If you are a contractor in real estate or road construction or mining, etc., do you often find yourself working on remote job sites without public grid supply or reliable power? When you have several large or heavy machinery that need to run at the same time, are you worried that your usual power supply does not have enough power to meet the use of these machinery and equipment?

If this is who you are, then if you have a large industrial-grade diesel generator, you can easily meet all your power needs anytime or anywhere.

So, how much power diesel generators can meet the power needs of these normal construction? Generally speaking, choosing a large industrial-grade diesel generator is a very large investment and requires more homework. If you are not sure what power diesel generator you want, don't worry, MAMOPOWER will tell you how to choose the right diesel generator for you.

If you are a contractor in real estate or road construction or mining and need to ensure that your project can continue even in the event of a blackout, blackout or blackout from the utility grid, then today MAMO POWER and our diesel generators Buying guide will be very applicable. Alternatively, in remote locations where electricity is not always available from the public grid, it is also suitable as a guide for choosing a diesel generator.

Therefore, even if the relevant unit informs you that they will shut down or limit your power supply, when your business or construction site has a Dingbo industrial diesel generator, you can still continue to work after a power outage.

Questions to ask when choosing a diesel generator

MAMO POWER recommends asking four main questions when purchasing an industrial grade diesel generator. Here, they give you the options available.

What type of fuel should I choose?

There are a few different ways to fuel a generator. Some smaller generators can run on natural gas or gasoline, but for larger generators (eg KW generators) diesel should be the fuel of choice.

Diesel generators provide heavy duty power for extended periods of time. And diesel is an inexpensive source of fuel that is easy to obtain or ship to your site.

Need continuous or standby?

How the generator is used as needed will determine which type of generator will be chosen. For example, for a kw generator, three base loads may need to be considered.

First, this is what most people think about when they consider leaving a generator on site in case of a power outage. These types of generators may or may not be on the sidelines. They only need to power your most important devices until you restore power.

Second, might consider keeping a generator on-site to cover those peak hours when your electricity usage might spike. Having an alternative power source will keep it running strong during these prime load times.

Third, for heavy duty diesel generators that will continue to be relied upon. If you find yourself frequently working on remote job sites where electricity may not always be available, having a kW diesel generator will give you peace of mind while doing these jobs, as you can run the generator continuously and provide power for all your heavy machinery Provide power.

Where to install the generator?

When considering purchasing your next generator, consider where to install it? Install indoors or outdoors? Or does it need to be moved or left in one place permanently?

Also, consider whether it needs to be weatherproof? Many generators are packed in silent boxes or shipping containers to protect it from the weather. Silent boxes also help reduce noise emissions, which may help if you're near a residential area. MAMO POWER

If you need a generator that can be moved, then consider a mobile trailer-type diesel generator, a unit that takes the generator to where you need it, anytime, anywhere.

Did you get enough capacity?

For example, using a kw diesel generator, a large amount of electricity can be obtained for the large equipment of the enterprise. But doing the math and making sure your business doesn't come to a standstill in the event of a power outage is a must-have preparation.

Start by deciding what the minimum viable output needs to be, and which equipment is critical to continue day-to-day business without power. Add up the wattage needed to run each basic project, then use one of our power calculators to make sure you get all the power you need.
