More is Less of a Problem With Generator Hire

When it comes to generators, overpowered is never as much of a problem as underpowered. Residential energy generators can be single-phase, but larger applications – especially industrial organisations – require three-phase generator hires that ensure dependable, failsafe power.

If you rent more (or less) generator than you need, your generator hire professionals will help you choose a better size. However, if you buy more generator than you need, you not only spend more for your initial purchase, you’ll spend more on installation, fuel, maintenance, repairs, and storage.

The Power Factor

Appliances like HVAC (heating, ventilation, air conditioning) units use a lot of power, so you need a bigger generator. Smaller appliances – especially those with moving parts, like fans and water pumps – use a great deal of startup power but use less energy once they are up and running. One easy method to estimate residential power needs is to calculate the wattage needed to operate and multiply by 3 to cover startup energy use.

The difference between a kW (kilowatt) and a kVA (kilowatt volt-ampere) is called “the power factor.” A kW represents the real power and a kVA is the “apparent power,” so the power factor is an approximate value. The kVAs will always be higher than the kWs.

Prime power ratings can be defined as having an “unlimited run time,” or essentially a generator that will be used as a primary power source and not just for standby or backup power. A prime power rated generator can supply power in a situation where there is no utility source, as is often the case in industrial applications like mining or oil and gas operations located in remote areas where the grid is not accessible. – Industrial Generator FAQs

Thanks to technological and electrical engineering advancements, you have many generator hire choices. The first step is to list every appliance and application for which your generator will be used then divide kWs by .08 pf (power factor) to convert to kVA. Here’s an example:

  • 2000 Watts = 2.5 kVA
  • 4800 Watts = 6 kVA

To convert kVA to kW, multiply by .08 pf.

The Right-Size Generator

Your generator hire or purchase should:

  • Be as fuel efficient as possible
  • Meet safety standards
  • Perform efficiently for long-term use
