Tips for Buying a Diesel Generator

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 solely based on price.

First and foremost, don’t buy something cheap if it means quality will be sacrificed. If you search online, you’ll find tons of diesel generators being sold with no brand, backup or quality control. 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 short, buying cheap makes you spend more.

Do your homework.

House backup often starts at 5kW, which is barely sufficient for the whole house. Each household uses a different set of products, so their power consumption will surely differ. 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.

Find out your kW from 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 boils down to personal preference. You will know how to deal with a power cut scenario. 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 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. 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 an issue of what floats your boat.

Consider 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. You’d like to balance personal preference and environmental compliance. A little research will surely take you far.
