Generac Magnum Mobile Diesel Generators - Major Power for Major Projects

Posted by on

Big jobs get done with planning and determination, but no one should lose time waiting for their power needs to be reliably met. For the professional with no time to waste, Generac provides a full lineup of mobile diesel generators for major projects. With a range of power output from 20 to 200 kilowatts, there’s a model for every kind of job, but deciding which generator to get is an important first step.

When you need a towable generator to power large events, respond to disasters or run construction sites, it’s best to focus on three factors: ease of use, maintenance, and maximum power needs. If you don’t have these pinned down, time gets wasted and opportunities get missed.

All of Generac’s generators are designed with ease of use in mind. You’ll find multiple options for trailer hitch ball sizes and fully-lockable cabinets. The Power Zone digital controller is easy to read during the day and night, and there are multiple convenience outlets on every model. Automatic remote start is also available on most units, which can reduce a trip to the generator when you’re already where the work needs to be done.

All the parts that require routine maintenance, from air filters to oil plugs, have been intentionally designed with easy access in mind. You won’t ever need to link multiple socket extensions to pull a spark plug on these generators. And you don’t have to worry about rust for a long time since they come with an industrial powder coat finish.

The most important factor to determine before selecting a generator is your maximum power requirement. Overloading a generator wears it out faster and can cause it to overheat. It’s also not a good idea to use a generator that’s too powerful for your job. This is why it’s crucial to do the math before making a purchase.

To determine your power needs, look at the tools you plan to connect and find the label that explains their wattage needs. Some tools and devices just have a set running wattage, which means they draw the same amount of power when they’re running as when they’re starting. Others have different wattage amounts for running and starting. Total the running wattages for everything you plan to use at the same time, then add the starting wattages to the total (if you think you might start everything at the same time, otherwise, just add the largest starting wattage). You’ll also want to give yourself some wiggle-room, just in case you missed a device. A good rule-of-thumb is an extra 10 percent of wattage should be added to your total. Once you have your final number, you know what size generator to buy.

Now that you know what to consider when buying a generator, here’s a quick look at Generac’s mobile diesel generator line-up for large projects:
