Looking at investing in a generator? Generators are basically the lifeblood of most construction sites, outdoor events and infrastructure projects throughout Australia.
We have you covered for all four important aspects you need to focus on when buying a diesel generator. EGH – One of the best generators for sale.
#1 – The Modular Capability
Even if you’ll begin with one machine, it is important to inquire from the equipment manufacturer the steps to take in order to parallel one machine with others to form a simple modular power plant.
For example, is the machine equipped with the capability by default? In addition, how long would it take to pair two generators? With most generators, this process takes less than 10 minutes. Unfortunately, not all generators provide this capability.
As a result, it is advisable that you check before making any investment since this capability could be required in the future.
When synchronised with a network of controllers, most plug-and-play generators will easily power up and down depending on the power requirements at a specific instance. For instance, only a maximum of two generators could be operational in instances of low load, therefore increasing fuel efficiency. Equally, all units could be activated when there’s a high demand for power.
Modular capability in generators also comes with several other benefits. First, there is enhanced equipment reliability since the failure of one generator is mitigated through the configuration of other generators to increase output in order to maintain the same power output. Second, the length and cost of service intervals is minimised, since it is important to stop power delivery in instances when maintenance operations take place.
#2 – Control Systems and Power Management
The right control system should provide various features. For example, the ability to remotely program and start the generator, show warnings, for example performance problems and low fuel, in addition to providing crucial analysis data. This aids in better utilisation of the overall power plant’s efficiency while giving a good overview of the entire application process.
Modern generators come equipped with Power Management Systems. An aspect that makes them suitable for rental applications is their plug-and-play design which allows for rapid and easy configuration. This type of system is recommended by professional electrician Sparks Power who advise “For home generators you do not want to have to be an experienced electrician to use it, power management systems are easy to use and maintain, this keeps your family safe when using the generator in your home”.
Power Management Systems give a means to optimise the performance and fuel consumption of parallel generators with load demand, starting and stopping the units with a corresponding increase or decrease in load. PMS also helps mitigate engine damage to units running at low-load levels, therefore boosting their overall work life.
#3 – Autonomy And Fuel Efficiency
All thanks to several energy efficiency improvements and design innovations, modern-day generators use less fuel that was the case five years ago. The sole fact that modern equipment can run for extended periods and more economically has been a crucial driver in the growth of the market. However, generators are not all made the same and fuel could be expensive.
As a result, you should inquire from two or three manufacturers about the fuel consumption forecast before putting your money into the purchase.
In addition, modularity helps increase fuel efficiency. For instance, using the demand patterns of the standard industrial application as something to go by, deploying a 1 MVA generator as the main power source could result in a daily fuel consumption of 1.677 litres. This compares to about 1.558 litres of generator fuel if three 325 kVA units were running at the same time.
There are now numerous options for fueling generators, including natural gas and bio-gas. While this is an emerging market, it is essential that you discuss there trends with a manufacturer before putting any money into buying a new generator.
#4 – Physical Size And Transportation
It is equally important that you establish whether a generator can be loaded or towed on a truck and look for features like forklift sots and lifting eyes. Transportation experts Camex explain “Being able to easily maneuver our generators is key to saving money on labour costs and ensuring our work starts as soon as we arrive at a new site. We have managed to save thousands in labour cost with this simple solution”.
If you are looking for multiple units, it is important to consider whether the units could be placed on top of each other to save on space and make them more accessible.
These aspects have great significance when it comes to total operating expenditure as well as efforts to minimise carbon costs.
Are you ready to invest in your own diesel generator?
Take into account all the foregoing attributes that influence your choice of appropriate sizing. Should you be in doubt, use a simple rule to estimate motor starting: 1 kW of generator set the rating per 3/4 to 1 hp as indicated on the motor nameplate.
You should approach the purchase in a conservative way bearing in mind that generators are designed to push hard and greater results are obtained when the unit’s sizing is as accurate as its application.
It is advisable that you think modular since bigger will not always be better. Modular isn’t all about big units and makes great sense when looking at units in the 150 kVA level.
For contractors, event companies and users who are looking to invest in a generator, this is the time to get expert advice regarding the most recent developments and which are designed to aid in matching outputs to specific applications.
