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 solely based on price.
First off, never buy cheap if it means compromising on quality. Searching online, you’ll easily find loads of diesel generators being sold sans backup, quality control or even a brand. You can actually buy one that looks exactly like its more expensive counterpart, but you certainly can’t expect the same performance. What’s worse is that they don’t come with a warranty. In short, buying cheap makes you spend more.
Do some homework.
House backup usually starts at 5kW, which isn’t actually enough for the whole house. Not all households have exactly the same products, so they may differ in power consumption. If you think you will need 5kW during backup, buy a generator that can run bigger. 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. Keep in mind that power factor is produced not by the generator but by the load. Therefore, the generator needs to be capable of reacting to power factor in the load.
Decide if you want auto switching during a blackout.
This part depends mainly on your personal preference. You decide how you want to deal with a power cut situation. Some people are happy with a manual switch that requires them to apply loads one by one, but what if the blackout occurs at night? Although automatic generators are a bit pricier, they do offer great convenience. If you do think an automatic generator is for you, make sure you get one that is ATS-ready. Some types will need you to buy a receiver unit as well as a communication cable. Cheap or unbranded generators usually don’t work with an ATS at all, meaning they will only work with manual intervention. Again, this is all about what works for your situation.
Consider environmental impact.
Finally, choose a generator that is known for being environment-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. Be sure to balance your personal needs and compliance with environmental regulations. Certainly, a bit of research will go a long way.
