The Perkins generators listed on this page run from a 9 kVA / 7 kW set to a 1650 kW / 2062.5 kVA plant. Same engine badge, very different jobs, so the fastest way to a sensible quotation is to start from your load rather than from a catalogue number.
Dingbo Power builds these sets in Nanning, Guangxi and exports them. Listed sets are generally 50 Hz, three-phase 400/230 V; if your site is 60 Hz, single-phase or uses another voltage, say so in your first message, because engine speed, alternator and ratings change with it. Below: how the range breaks down, what the engine codes tell you, and what really moves the price of a Perkins generator set.
Four size bands, four different questions
9 – 27 kVA
Shops, small farms, telecom cabins, single sites with modest loads. The deciding factor is usually single- versus three-phase, and whether a compressor or pump has to start on it.
9 kVA · 20 kVA · 27 kVA
30 – 101 kVA
Workshops, schools, hotels, small plants. Motor starting becomes the constraint here, and this is the band where an ATS is most often ordered with the set.
30 kVA · 63 kVA · 101 kVA
125 – 250 kVA
Factories, commercial buildings, hospital wings. Six-cylinder engines take over; enclosure size, fuel tank and site altitude and temperature start to matter as much as kVA.
150 kVA · 250 kVA
Reading the Perkins engine code
The model number on a datasheet is more informative than it looks. The first digits give the engine family and cylinder count, and the last digits before the suffix give displacement in litres. A three-cylinder 3.3 L engine and a six-cylinder 15 L engine are not variations of one product; they are different machines with different service and space needs.
| Dingbo listing | Perkins engine | What the code suggests | Ask before ordering |
|---|
| 30 kVA / 24 kW | 1103A-33G | Three-cylinder, 3.3 L, no turbo | Motor starting margin, available floor space |
| 250 kVA / 200 kW | 1206A-E70TTAG3 | Six-cylinder, 7.0 L, twin-turbo | Ambient temperature and altitude derating |
| 400 kW / 500 kVA | 2506C-E15TAG1 | Six-cylinder, 15 L, turbocharged | Whether the set label is a prime or standby figure, and the engine's own rating at the same duty |
Standby, prime and the kW/kVA gap
Two numbers cause most of the confusion. First, kVA is not kW: at a 0.8 power factor, 250 kVA delivers 200 kW, which is why so many listings above carry a pair of figures. Second, the same Perkins-based set carries a higher standby rating than prime rating. As a rough pattern on 50 Hz sets, standby sits around 10% above prime (for example 40 kW standby against 36 kW prime on a 50 kVA class set), but the exact pair depends on the engine and alternator, so take it from the model-specific datasheet rather than from a catalogue title.
Standby means occasional running during a utility outage. Prime means long, regular hours at a variable load, typical of a remote site with no grid. Choosing a standby-rated figure for prime duty is the most common way a generator ends up undersized on paper and overworked in practice.
Perkins generator price: what actually moves the quote
Prices depend on the complete configuration, which is why two quotations for "a 200 kW Perkins generator" can be far apart. The differences normally come from:
Engine variant and emissions specification, if your market requires a particular stage.
Alternator brand: Stamford, Leroy-Somer, Marathon, Engga and others can be specified, and they are priced differently.
Controller and transfer gear: SmartGen or Deep Sea controllers, and whether an automatic transfer switch or paralleling panel is included.
Housing and fuel: open frame, silent canopy, container or trailer, plus base or daily fuel tank size.
Delivery basis: export packing, freight, destination port and the trade terms in the quotation.
For a real reference, the 120 kW Perkins silent generator exported to Zambia was documented with a Perkins engine, Stamford alternator and SmartGen controller. Ask for the same level of component detail on any set you compare.
When a different engine may serve you better
Perkins is a strong fit when its parts and service are easy to reach where the set will run. If your fleet or local dealer network is built around another brand, a Cummins or Volvo set from the same factory may be the more practical choice. For backup-only sites, our note on emergency versus standby generators and the guide to commercial backup generators are useful starting points.
Common questions
How much does a Perkins diesel generator cost?
There is no single price for a rating. The figure depends on the items listed above and on the delivery terms. Send your kW or kVA, voltage, duty and destination and we will quote a specified configuration rather than a headline number.
Do you supply 60 Hz or single-phase sets?
The listings here are mainly 50 Hz three-phase. Other frequencies, voltages and phases may be possible on a given model; confirm before ordering, because a 60 Hz set runs at a different engine speed and has different ratings.
Will the set start automatically when the grid fails?
Only with a compatible auto-start controller and transfer equipment. Tell us at the enquiry stage so the generator and ATS are specified together.
Can I get the datasheet before deciding?
Yes. Ask for the model-specific datasheet with the prime and standby figures, the alternator and controller models, and dimensions for the enclosure you want.
Tell us the load, we will name the set
Include: required kW or kVA, largest motor, standby or prime duty, voltage and frequency, site altitude and temperature, open or silent housing, and destination country. We will reply with a suggested model, its datasheet and an itemized quotation.
