Sizing Tool
Choosing the correct generator size is critical to the success of your project.
Accurate Power Estimates in Seconds.
To get your estimation, simply define your project by selecting your Phase, Load (in kW or Amps), and the hire Duration. Our tool instantly analyses your data, cross-referencing against our fleet specifications and UK compliance standards to provide a tailored recommendation for a kVA rating. This includes a 25% safety margin to ensure your site operates with maximum efficiency and reliability.
Why Sizing Matters
Correct sizing is the difference between seamless operations and costly downtime. An undersized unit can lead to equipment failure, while an oversized one results in “wet stacking” engine damage and unnecessary fuel costs. Our calculator ensures your project runs with optimal efficiency, reliability, and full compliance with UK environmental standards.
Expert FAQs
Our specialists have answered the most common technical questions to help you understand the variables behind your power calculation. These insights ensure you select a setup that maximizes efficiency while remaining fully compliant with UK site regulations.
What is the difference between kVA and kW?
In simple terms, kVA (Apparent Power) is the total amount of power being used by a system, while kW (Real Power) is the portion of that power doing the actual work. For most industrial generators, we calculate using a standard 0.8 power factor.
