How to Buy a Diesel Generator

You have to consider a number of factors before purchasing a diesel generator. By carefully reviewing your options and requirements, you will be able to complete this task more easily.

Don’t buy solely based on price.

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 short, getting a cheaper alternative almost always makes you lose money.

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 your expected power requirement during backup is about 5kW, you’ll need a generator larger than 5kW. Always consider inrush current, which can triple the actual power needed to run a certain item.

Determine 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. 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 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 fine manually switching the generator on and applying the loads themselves, but what if the blackout occurs at night? Although automatic generators are a bit pricier, they do offer great convenience. If you do decide to buy an automatic generator, make sure it is ATS-compatible. There are types that need you to get a receiver unit and communication table. However, some cheap or unbranded generators are not ATS-compatible at all, which means manual operation is your only option. 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 actually have green settings that minimize emissions and carbon footprint, but of course, there will be certain brands and models that do the job better than the rest. Be sure to balance your personal needs and compliance with environmental regulations. A little research will surely take you far.
