Ideal Generator Sizes For Doubling Output — What To Consider?

Choosing the Right Generator Sizes

When doubling generator output, it’s essential to select units with compatible voltage and frequency ratings. A common approach is to match the voltage and frequency of the existing generator with the new one. For example, if the existing generator is a 16-kilowatt, 120/240-volt, single-phase unit, the new generator should also be 120/240-volt, single-phase. This ensures a seamless connection and prevents damage to the generators or the electrical system.

Generator Parallel Kit Selection

The type of generator parallel kit used also plays a crucial role in doubling output safely and efficiently. A parallel kit enables multiple generators to operate together, sharing the load and providing a stable power output. When choosing a parallel kit, consider the following factors: the kit’s amperage rating, which should match or exceed the total amperage output of the generators; the kit’s voltage rating, which should match the generators’ voltage; and the kit’s compatibility with the generators’ control systems.

Load Capacity and Generator Sizing

When sizing generators for doubling output, it’s essential to consider the load capacity and the total power required. A general rule of thumb is to add 10-20% to the existing load to account for future growth and power fluctuations. For example, if the existing generator is 16 kilowatts and the load is 12 kilowatts, the new generator should be sized to handle at least 13-14 kilowatts to accommodate the increased load and ensure reliable operation.
