Hyundai 8kva Generator and up to What Extent It Can Provide You Power? What is a Hyundai 8kva generator capable of? This question might seem like it should simply be about the 8kVA power supply and how much that is in terms of actual devices, but when you know the range of models that Hyundai generators Australia has on offer, even in just the 8kVA range, you start to realise that Hyundai generators are versatile. In this article, we cover not only what 8kVA looks like in terms of devices that can be powered, but we also cover the differences between petrol, diesel, and inverter generators at the 8kVA power range. There are also bells and whistles to consider, such as electric start. How to know if 8kVA is enough It can be tricky to find out exactly what power output you need to sufficiently power everything you need your Hyundai generators Australia to be able to power. Firstly, some devices have both start-up wattage requirements and running wattage requirements. A prime example of this
is a refrigerator. Fridges can draw 1.8 kW (1800 W) when starting up but then run at the comparatively meagre requirement of only 180 W. This means that if you try to plug in multiple fridges at once they can trip out the generator more easily than if you plug them in one at a time and let them settle down to their running requirements because the initial draw of plugging them in all at once can be ten times as much as they require to simply run. Watts versus volt-amps And then there is the confusion of kilowatts versus kVA (kilovolt-amps). The important distinction is that the kVA measure takes into account how inefficient the device is. The power factor of a device determines, in essence, how much of the power supplied to it that it uses. So, if a device is inefficient and has a power factor of 0.5 that means that it uses 50% of the power supplied to it, so while it’s rated at, for instance, 200W it needs 400VA to work properly. This simplified explanation is enough to understand what this means for Hyundai generators. Power analysis When you analyze your devices to find out how much power your generator will need to supply, you need to find the power factor and the power requirements (both start-up and running) of each device. Then you can use an online calculator to convert all the numbers from watts to kVA. Finally, you can add up all the running power requirements. If you want to be able to start up all the devices at once, then you need to instead add the start-up power requirements. If you don’t want to start them all up at once and you’re sure that the power requirements of the devices won’t surge back to their start-up requirements (such as when a fridge door is opened and it kicks into high gear to cool it down again), then only add on to the total the highest start-up power requirement there is. This means you have a little wiggle room to work with as you plug each device in so you don’t trip the generator, but if you are running critical devices then it’s better to just add up all the start-up power requirements. Let’s run through an example where you have an 8kVA generator and want to power on several fridges all at once and those fridges have the start-up power requirement of 1.8kVA and a power factor of 0.8. This means they need 2.25kVA each all at once so you can only power on three (6.75kVA total). If you let them start up one at a time, and they run at 0.225kVA running power requirement, then you could get way more of them running. The only problem is that you couldn’t open the fridge doors because then their power requirements would surge. And if you opened more than one fridge door at a time, you could trip out the generator. Diesel versus Petrol Several differences between petrol and diesel engines affect their performance as generators and they relate to the difference in technology between them. Diesel engines use super high
pressure to ignite their fuel and air mixture. This means that the pistons in diesel engines have to be designed so they compress the air. One way of doing this is to make the pistons longer, so they can hold more air but all that air is compressed into the same volume of space, making it higher pressure. This does mean, though, that the pistons take longer to reciprocate. As such, the RPMs of a diesel engine are usually lower. However, the torque is higher with the extra punch that diesel packs. This is why diesel engines are better for moving larger machines which need a lot of torque to get started moving. On top of this, the high air pressure that diesel engines are subject to means they have to be constructed so they’re tough enough to withstand it. Because petrol engines don’t have to deal with this, they can be designed to be smaller and still be functional. Petrol engines use spark plugs to ignite their fuel-air mixture at a lower pressure. Because diesel engines are more efficient and petrol engines can be made smaller, the lower end of the power spectrum in generators is pretty much all petrol and the higher end of the power supply spectrum (up to hundreds of kVA) is diesel. Diesel makes more sense if you plan on running your generator for hours at a time because the higher upfront cost of the machine and the higher cost of fuel will be paid off by the higher running times and better efficiency. Inverter Generators Inverter generators can be either petrol or diesel, though they are usually petrol because they are usually smaller. This is because the problem they aim to solve is worse at the lower end of the power supply. That problem is the high Total Harmonic Distortion (THD) of generators. Generators spin magnets around past a coil of wires, generating electricity. The problem is that they’re not super consistent at this spinning motion which means the power that the generator is ‘distorted’. Distortion is a problem because it can cause power surges or sags which can break sensitive devices, such as the compressor in a fridge. Inverter generators fix this problem by running the power through a rectifier, so it goes from AC to DC, and then through an inverter, so it is converted from DC back to AC. This rigamarole has some great benefits, the first of which is reducing the distortion to acceptable levels. It also means the generator doesn’t have to run at a high speed to keep the frequency of the power it generates at an acceptable level, since it’s converted to DC and then back to AC anyway. All this results in a more fuel-efficient generator, quieter, and better suited to powering sensitive devices like electronics. It does, however, mean the generator is more costly upfront and is harder to repair and maintain because of the extra components within it. Optional Extras
Generators also come with features such as an electric start. This lets you turn on the generator at the press of a button, rather than through the traditional method of yanking on a starter cord over and over until things finally kick into life and you can power up your fridge before everything inside spoils or you can get to work on your worksite and start welding before the sun goes down. Remote starting is another feature often coupled with electric start, allowing you to power the motor up with a remote. Generators are loud and if you have to start one up at the beginning of every day, it’s not the best way to get your morning started with a loud noise and engine fumes. It also makes it easier if your generator is in an enclosure that is hard to access or is locked away. This is often the case because generators need to be outside or kept carefully so that no one can be harmed by the fumes. Fumes and Generators You have to ensure that your generator is kept outside or in a well-ventilated area when it’s in use. Carbon monoxide is a toxic gas that is colourless and odourless. This means it can poison people without them even being aware. Generators produce this gas. Several generators have carbon monoxide readers built in these days, but it can be worth keeping a reader on-site regardless of if the generator has one or not to save potential victims from a possibly lethal risk. One way to do this is to build a structure that keeps the generator protected from the elements above but allows the air through the sides, for instance, through a chain-link fence-style wall. Conclusion There are several 8kVA generators on offer, both in the diesel range, the petrol range, and the inverter range. Each one is suited to different needs, with diesel engines working best for hours on end and petrol and inverter generators working better on a smaller scale. Inverter generators are best for cases where your devices are sensitive to power fluctuations, which is an unfortunate problem that most generators have, especially on a smaller scale. Hopefully, this has been a useful article for your purposes and you can go forward with understanding a little bit more about generators, including their range of applications, their capabilities, and safety best practices.
