100 kVA Diesel Generators for Reliable Power

A 100 kVA generator is a versatile choice for commercial buildings, industrial facilities, agricultural operations and construction sites. It can provide standby power during an outage or serve as a prime power source where a stable mains supply is unavailable.

Our range consists of 3 phase generators operating at 50Hz. Each model uses a proven diesel engine and is supplied in a weather-resistant acoustic canopy. This makes the range suitable for applications that require dependable output with lower operating noise than comparable open generators.

Global Generators supplies equipment from the UK to customers across the country and worldwide. As a leading stockist, we hold a wide range of generators in our physical inventory. Stock availability enables us to arrange fast UK delivery and efficient global export without the extended lead times often associated with factory orders.

Our team has more than 50 years of combined generator industry experience. We can help you compare specifications, understand operating requirements and select a suitable power solution for your site.

Choosing a 100 kVA Generator

The correct generator must be able to support the combined electrical load while retaining enough capacity for starting currents and changes in demand. Equipment such as pumps, compressors, motors and refrigeration systems can draw considerably more power during start-up than during normal operation.

A typical 100 kVA genset provides approximately 80 kW at a 0.8 power factor. However, this does not mean that every application with an 80 kW calculated load should automatically use this size. Allowance may be required for load growth, motor starting, operating conditions and the recommended loading range of the generator.

Choosing from appropriately sized generators ensures that the connected equipment receives stable power without repeatedly overloading the set. Oversizing should also be avoided where possible, as running a diesel generator at very low loads for extended periods can affect efficiency and engine condition.

Our experts can review your expected loads and help establish whether a 100 kVA diesel generator offers sufficient capacity. If your requirements are likely to increase, comparing it with a 150 kVA generator may provide useful context.

100 kVA 3 Phase Diesel Generator Applications

A 100 kVA 3 phase generator is designed for sites with three phase electrical systems. Common uses include workshops, manufacturing facilities, farms, warehouses, offices, telecommunications equipment and small commercial developments.

For temporary or remote operations, a 100 kVA 3 phase diesel generator can support site cabins, lighting, tools and selected machinery. It is a powerful generator for many medium-duty applications, although the exact equipment it can run depends on simultaneous demand and starting loads.

A 100 kVA 3 phase genset can also protect critical operations against interruptions to the mains supply. When installed with a correctly specified automatic transfer switch, it can start automatically following a power failure. The control panel monitors the generator and displays key operating information, while the transfer equipment manages the change between mains and generator power.

For businesses that need long-term resilience, purchasing a generator can offer greater control and availability than relying on generator hire whenever an outage or project occurs.

These models are not intended to provide a dedicated single phase output. If the site only has single phase equipment, explore our single phase generators or ask our team to assess the proposed distribution arrangement.

Silent Canopied Generators

Every model in this category is supplied as a 100 kVA silent generator. The acoustic canopy helps reduce noise while protecting the engine, alternator and electrical components from weather and accidental contact.

A 100 kVA silent diesel generator is well suited to locations where sound levels and equipment protection are important. Potential settings include residential developments, retail premises, hospitality venues, healthcare facilities and occupied commercial sites.

Canopied sets also provide a practical package for outdoor use. Access doors support routine inspection and maintenance, while an integrated fuel tank allows the generator to operate without a separate day tank in many standard installations. Exact tank capacity and running time vary by model and load.

Although the canopy reduces sound, “silent” does not mean inaudible. Final noise levels depend on the model, measurement distance, site layout and surrounding surfaces. Additional attenuation may be needed for noise-sensitive projects. You can compare further options within our wider range of silent generators.

Cummins and Grupel Generator Options

Our selection includes Cummins generators powered by Cummins engines and Grupel generators powered by Perkins engines. Global Generators is an authorised Cummins CPG reseller and an authorised Grupel dealer, enabling us to provide genuine equipment, expert product knowledge and highly competitive UK pricing.

We also supply Grupel generators fitted with Perkins engines. These models combine established engine technology with a robust canopied package for commercial and industrial applications.

The available models differ in their dimensions, dry and wet weights, fuel capacity, controller, acoustic performance and standard equipment. Comparing these details is important when access, transport, installation space or operating time is a key consideration.

Both options are 100 kVA diesel units designed to deliver reliable power at 50Hz. Browse our broader 50Hz generators if you need to compare this output with other capacities.

Prime Power and Standby Power

Prime and standby ratings describe different operating duties. Prime power is used where the generator supplies a variable electrical load for extended periods, subject to the manufacturer’s stated operating limits and maintenance requirements.

Standby power is intended for emergency use when the normal mains source fails. A standby generator must remain ready to start when required, making correct servicing, battery maintenance and fuel management essential. Our range of standby generators covers multiple output sizes for commercial and industrial backup applications.

The quoted 100 kVA rating may refer to standby output, with a slightly lower prime rating. Always check the individual data sheet rather than assuming that every 100 kVA diesel genset has identical ratings or operating limits.

Efficient Diesel Power from a UK Stockist

Modern diesel generators provide reliable power solutions for applications where durability, operating range and strong load response are important. The actual fuel consumption of any model changes according to load, engine specification, site conditions and maintenance.

A 100 kVA 3 phase diesel genset can offer an effective balance between output and physical size. Selecting the right model also involves considering access for delivery, ventilation, exhaust routing, cable installation, fuel storage and future servicing.

We supply generators from the UK rather than limiting our service to the domestic market. Our team can support customers arranging local delivery or international shipment, with stock models available for efficient dispatch.
