Basic Sizing for Mobile Generators

Understanding the Fundamentals of Mobile Generator Sizing

Whitepaper by Generac Industrial Power

Abstract

Selecting the optimal generator for your mobile power needs is a critical decision that directly impacts operational reliability, performance, and long-term cost-efficiency. While many manufacturers provide online sizing calculators, understanding the underlying engineering principles behind those recommendations is essential to ensure your selected equipment is truly fit for your specific application.

The Importance of Accurate Sizing

Accurate sizing is more than just selecting a unit with sufficient power output; it involves a detailed analysis of your load profile, expected duty cycles, and the unique environmental conditions of your work sites.

We highly recommend working directly with a qualified generator representative during the planning phase. A professional assessment ensures that your mobile power solution:

• Matches Peak Demand: Provides sufficient capacity to handle the startup currents and peak loads of your equipment without risk of system trips.
• Optimizes Performance: Prevents "under-loading" issues, which can lead to engine wet stacking and premature component wear.
• Ensures Long-Term Value: Balances your immediate power needs with headroom for potential equipment growth, ensuring your investment remains relevant as your project demands evolve.
