Tips for Buying a Diesel Generator
There are lots of things to look into before buying a diesel generator. With careful evaluation of your requirements and available options, you can make this task a whole lot easier.
Don’t buy based on price alone.
First of all, never buy cheap if it means quality will be compromised. Searching online, you’ll easily find loads of diesel generators being sold sans backup, quality control or even a brand. You’ll surely find one that looks just like its more expensive equivalent, but it will be as good in terms of performance. What’s worse is that they don’t come with a warranty. In other words, the cheaper alternative almost will actually cost you more.
Don’t skip your homework.
House backup usually starts at 5kW, which isn’t actually enough for the whole house. Each household uses a different set of products, so their power consumption will surely differ. If your expected power requirement during backup is about 5kW, you’ll need a generator larger than 5kW. Always take inrush current into consideration and that it can triple the actual power required to run an item.
Know your kW based on your kVA.
Apparent power or kVA may be considered as a particular power output is obtainable from specific products, depending on two things – running appliances and the power of the machine that runs them. You have to take note that the load that produces power factor and not the generator. Therefore, the generator needs to be capable of reacting to power factor in the load.
Decide if you need an automatic switching feature during a black out.
This part boils down to personal preference. How you handle a power cut situation is for you to decide. For some people, manually switching on their generators and applying the loads themselves is good enough, but what happens when the power cut happens at night? While it can be a little more expensive, an automatic generator does make things more convenient. If you are more interested in buying an automatic generator, just be sure it works with an ATS. Some types require you to purchase a receiver unit and communication cable. However, there are cheap or unbranded generators that don’t work with an ATS at all, which means they can only work with manual operation. Again, this is all about what works for your situation.
Consider the generator’s environmental impact.
Lastly, pick a generator with a reputation for being earth-friendly. All generators have green modes that lessen emissions and carbon footprint, but of course, some brands and models will be better at it than the others. What you want is to balance personal preference and adherence to environmental regulations. Just a bit of research can go a long way.
