Prime power (PRP): The power that the generating set can supply continuously with variable load for an unlimited number of hours per year, while observing the maintenance intervals specified by the manufacturer for the stated ambient conditions (according to ISO 8528-1). The average power delivered over a defined period and any overload must remain within the percentages specified by the manufacturer.

Standby power (ESP): The maximum power that the generating set can supply for a limited time while observing the maintenance intervals specified by the manufacturer for the stated ambient conditions according to ISO 8528-1. The number of hours per year is specified by the manufacturer. Overload is not permitted.

Note: All values are nominal values from the original technical datasheets of the engine and alternator. Values may change without notice and can vary by up to ±5%.

What is the difference between PRP and ESP?

PRP is the prime power rating for the defined operating profile; ESP is the emergency standby rating. They must not be treated as interchangeable continuous ratings.

What is checked before selection?

Load profile, motor starting currents, voltage, frequency, operating mode, site conditions, noise requirements and transfer concept.
