You have to consider a number of factors before purchasing a diesel generator. With careful evaluation of your requirements and available options, you can make this task a whole lot easier.
Don’t buy on price alone.
First and foremost, don’t buy something cheap if it means quality will be sacrificed. Searching online, you’ll easily find loads of diesel generators being sold sans backup, quality control or even a brand. You can get one that looks exactly like its pricier counterpart, except it won’t perform as well. Worse, they won’t come with a warranty. In other words, the cheaper alternative almost will actually cost you more.
Do some homework.
House backup often starts at 5kW, which is barely sufficient for the whole house. Not all households have exactly the same products, so they may differ in power consumption. If your expected power requirement during backup is about 5kW, you’ll need a generator larger than 5kW. Always consider that inrush current can triple the actual power required to run certain items.
Find out your kW from your kVA.
Apparent power or kVA is sometimes considered as a specific power output could be derived from particular products, depending on the machine’s power and what appliances are switched on. It is important to know that the load, not the generator, produces power factor. Thus, the generator must have the capacity to react to power factor in the load.
Decide if you want auto switching during a blackout.
This part comes down to your own preference. You will know how to deal with a power cut scenario. Some people are fine manually switching the generator on and applying the loads themselves, but what if the blackout occurs at night? An automatic generator can be a bit pricier, but it does make everything easier. If you are more interested in buying an automatic generator, just be sure it works with an ATS. There are types that need you to get a receiver unit and communication table. 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.
Finally, select a generator known for being nature-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. You’d like to balance personal preference and environmental compliance. Just a bit of research can go a long way.
