The Excel Power XL-DC-550 500kVA Diesel Generator is a cornerstone of the Excel Power Standby Range, engineered to deliver robust performance when mains power fails. Designed for permanent installation in commercial facilities, private residences, hospitals, data centres, and industrial complexes, this 500kVA Genset combines cutting-edge engineering with user-centric features. Whether safeguarding critical operations during outages or serving as a primary power source in off-grid locations, the XL-DC-550 offers unmatched reliability, efficiency, and customisation.

Unmatched Power Output: Prime & Standby Performance

The Excel Power XL-DC-550 shines in both Prime Power and Standby Power scenarios, adapting seamlessly to your energy needs:

  • Prime Power 500kVA / 400kW: Ideal for continuous operation in remote sites or as a primary power source, delivering consistent energy output without performance degradation.
  • Standby Power 550kVA / 440kW: Optimised for emergency backup, providing up to 440kW during grid failures.

Operating at 1500 RPM, this 500kVA Diesel Generator ensures fuel efficiency, reduced mechanical stress, and quieter performance compared to high-speed alternatives.

Core Components: Built for Durability & Precision

At its heart, the Excel Power XL-DC-550 integrates industry-leading components for longevity and stability:

  • Heavy-Duty Cummins Water-Cooled Diesel Engine: Renowned for reliability, Cummins’ engine excels under heavy loads and extreme conditions. Water-cooling ensures optimal thermal management, even during prolonged use.
  • Stanford Alternator: Paired with the engine via anti-vibration mounts, this high-efficiency alternator minimises harmonic distortion and voltage fluctuations.
  • Anti-Vibration Mounts: Isolate mechanical vibrations, reducing noise and preventing structural wear.

This synergy guarantees smooth operation and extended service intervals, even in heavy industrial environments.

Precision Control & Voltage Stability

The Deepsea DSE6120 Control Panel offers intuitive monitoring and control:

  • Real-time diagnostics (voltage, frequency, oil pressure).
  • Configurable alarms and auto-shutdown to prevent damage.
  • Remote monitoring capabilities via USB or network interfaces.

Complementing this is a Fully Sealed Automatic Voltage Regulator (AVR) maintaining voltage within ±1%, critical for protecting sensitive electronics like servers and medical equipment from surges or drops.

Silent Operation & Extended Runtime

Engineered for environments where noise matters:

  • Close-Fitting Acoustic Canopy: Reduces operational noise by up to 75 dB(A), ideal for residential areas or noise-sensitive sites.
  • 960L Bunded Fuel Tank: Offers over an 8-hour runtime at full load (107L/hour), with a secondary containment layer to prevent spills. For extended operation, pair with External Tank Options.

Standard Features & Warranty Coverage

Every XL-DC-550 includes:

  • Coolant Heater: Ensures quick starts in cold climates.
  • Battery Charger: Maintains optimal battery health between uses.
  • 12-Month Warranty or 1000 Hours: Comprehensive coverage reflecting Excel Power’s confidence in durability. Plus expert technical support with service plans available directly from Hampshire Generators.

Customisable Upgrades for Enhanced Performance

Tailor your 500kVA Genset to specific needs with:

  • Three-Way Valves: Simplify fuel management between main and external tanks.
  • Control Panel Upgrades: Add advanced telemetry or parallel operation capabilities.
  • Ultra-Low Noise Canopies: Further reduce noise for urban installations.
  • Automatic Transfer Switches (ATS): Enable seamless transition from grid to generator power.
  • Alternator Auxiliary Winding (AREP): Stabilises voltage for nonlinear loads (e.g., UPS systems, variable-speed drives).

Excel Power XL-DC-550 500kVA Diesel Generator: Reliable Standby Power for Demanding Applications

The Excel Power XL-DC-550 500kVA Diesel Generator is more than a backup—it’s a strategic asset for uninterrupted operations. With its Cummins-Stanford core, intelligent controls, and customizable upgrades, it’s engineered to exceed expectations.

When will I receive my order?

In most cases, a product on our website will give you an indication of the current stock availability, but shipping is not uniform for all products. We maintain fantastic relationships with all of our suppliers and we aim to get products to customers within 3 business days of the order being taken. This availability is based on information from our suppliers and from sales and supply patterns. The availability information given is a guide only and not a guarantee as there are external factors that we may not have control over.

Coronavirus Update – UK couriers and transport companies will not currently guarantee delivery times and we are seeing a slight delay in deliveries – please bear this in mind when ordering.

Specialist Couriers – Some items such as the larger portable power stations are sent by specialist courier as standard couriers will not accept them. These specialist couriers are very reliable but sometimes don’t have tracking or timed delivery.

Split deliveries – We sometimes need to send orders for more than one item by different courier networks (portable power stations for example) – so you may receive items at different times.

1500rpm machines or larger diesel gensets however are typically priced on application and all depend on the destination. We will be happy to quote on any large diesel generator and discuss your needs over the phone or via email.

Most orders placed before 12pm on a business day will be shipped from our suppliers on the same day provided the product is in stock. If you need to be certain an item is in stock and available, or if you need a lead time, it’s worth calling our sales team on 01329 722390. Pricing for extended shipping areas like Northern Ireland, the Scottish Highlands and outlying Islands, Outer Hebrides, Channel Islands, Isle of Man, Scilly Isles, and other postcodes not considered as UK mainland can be obtained also by calling our offices.

Please note that the processing of a payment and acknowledgement email does not constitute a legally binding contact. In the case of mispricing, changes in stock quantity, or if we believe the machine will be misused, we reserve the right to cancel the order and provide a full refund.

Heavy Items

You will be contacted by phone after ordering a larger item to confirm a delivery date before your order is dispatched. Large or heavy items are dispatched through a pallet network, so if we can’t get in contact with you, we may be unable to send out your item on a next day delivery. Please be sure to include a working phone number with your order.

Heavy items will require the recipient to make arrangements to take delivery of the goods and may require the recipient to help the courier unload the item. For items that are delivered on a pallet the courier will leave the pallet as close to your door as possible.

1500rpm diesel generators will require forklift (or similar) offloading; if this is not available then we can arrange a Hiab offload at an additional price – please call us to discuss any delivery requirements.
