Excel Power XL-DK-22S 20kVA Single Phase Diesel Generator

When the grid fails, your life or business shouldn’t have to pause. Introducing the Excel Power XL-DK-22S 20kVA Single Phase Diesel Generator, a masterclass in power engineering designed to provide an impenetrable safety net for your electrical needs. As a flagship model in the Excel Power Standby Range, this diesel generator is meticulously crafted to bridge the gap between industrial-grade performance and residential-friendly operation. Whether you are protecting a high-end estate, a retail outlet, or a critical data hub, the XL-DK-22S offers the “install and forget” peace of mind that only comes from world-class manufacturing.

Unrivalled Prime and Standby Power Performance

The core of any reliable energy strategy is the ability to handle both sustained loads and sudden surges. The Excel Power XL-DK-22S 20kVA excels in both. It offers a Prime Power rating of 20kVA/20kW for continuous applications and a Standby Power peak of 22kVA/22kW.

Operating on a Single Phase (230V – 50Hz) configuration, this unit is specifically tailored for the UK market. Most standard home electric generators struggle with the high-draw demands of modern heat pumps, EV chargers, and luxury appliances, but the XL-DK-22S provides a clean, stable 230V output that mimics the mains supply perfectly. This makes it an ideal backup generator for home use where power quality is just as important as power quantity.

Robust Depco Water Cooled 1500RPM Engine & Alternator

At the heart of this machine lies the heavy-duty Depco water-cooled engine. Unlike high-speed 3000RPM portable units that wear out quickly under heavy use, this diesel fuel generator runs at a steady 1500RPM. This lower rotational speed significantly extends the lifespan of the internal components, reduces vibration, and enhances fuel efficiency.

The engine is seamlessly coupled to a high-quality Depco alternator. This synergy ensures that the mechanical energy is converted to electrical energy with minimal loss. Because the system is water-cooled, it can operate in high-ambient temperatures and dense enclosures without the risk of overheating, ensuring your standby power remains available even during the hottest summer blackouts or the most demanding winter storms.

Durable Engineering for Demanding Applications

The Excel Power XL-DK-22S is not just a piece of machinery; it is an investment in resilience. Every component, from the heavy-duty steel base frame to the high-grade internal hoses, is selected for its “over-engineered” durability. This single phase generator is built to withstand the rigours of commercial environments where downtime isn’t just an inconvenience, it’s a financial loss. The rugged construction ensures that the unit remains structurally sound and functionally reliable through years of outdoor exposure and cyclical use.

Precision Voltage Regulation with ±1% Stability

Modern electronics are sensitive. Computers, servers, and smart home systems can be easily damaged by the voltage “flicker” common in lower-end generators. The Excel Power XL-DK-22S 20kVA features an advanced Automatic Voltage Regulator (AVR) that maintains Precision Voltage Regulation with ±1% Stability. This means the power coming out of the generator is often cleaner than the power coming from the grid. You can power your sensitive laboratory equipment or home cinema system with total confidence, knowing that harmonic distortion is kept to an absolute minimum.

Advanced Datakom Control Panel

Managing your power shouldn’t require an engineering degree. The XL-DK-22S comes equipped with a sophisticated Datakom control panel. This intuitive interface provides real-time digital readouts of engine temperature, oil pressure, fuel levels, voltage, and frequency. It also acts as the “brain” of the unit, providing critical safety shutdowns and maintenance alerts. The Datakom system allows for easy integration with remote monitoring, so you are always in the loop regarding your generator’s health.

Acoustic Canopy: Silent Power for Sensitive Settings

One of the primary concerns for residential users seeking a backup generator for home use is noise. Excel Power has solved this with a high-specification Acoustic Canopy. This weather-proof, powder-coated steel enclosure is lined with high-density sound-attenuating material.

The result? It limits sound to 70 dB(A) @ 7m. To put that in perspective, it is roughly equivalent to the sound of a vacuum cleaner or a normal conversation. This makes it an ideal choice for residential areas, hospitals, or noise-sensitive commercial offices where a loud, clattering engine would be unacceptable.

Optimised 43l Fuel Tank for Extended Run Times

The Excel Power XL-DK-22S 20kVA features an integrated 43l fuel tank located safely within the base of the unit. This capacity is perfectly balanced to provide a full day’s work under typical load conditions without the need for constant refuelling. For those in remote locations or industrial sites, the fuel system is designed for easy access, making routine top-ups of your diesel fuel generator quick and mess-free.

Customisable Options for Tailored Power Solutions

No two installations are exactly the same, which is why the XL-DK-22S offers a suite of customisable upgrades to suit your specific site requirements:

• Automatic Transfer Switches (ATS): Essential for a standby power setup, an ATS detects a mains failure and automatically starts the generator, switching the load over in seconds.
• External Tank Option: For those requiring multi-day autonomy without refuelling.
• Three-Way Valves: For easy connection to bulk fuel storage.
• Battery Charger: Keeps the starter battery topped up during long periods of inactivity.
• Ultra Low Noise Canopies: For urban environments with strict decibel limits.
• Alternator Auxiliary Winding (AREP): Enhances motor-starting capabilities for heavy industrial machinery.

Warranty and Expert Support

Excel Power 1500rpm diesel generators are backed by a comprehensive manufacturer’s warranty for both domestic and commercial applications. Please review the specific coverage terms, mandatory commissioning requirements, and extended warranty options below:

Standard Coverage (Private & Commercial Use)

• Warranty Period: 1-Year (12 Months) / 1,000-Hour Limited Warranty (whichever occurs first).
• Applies To: Both private/domestic and commercial installations.

Mandatory Commissioning Requirement

To validate your standard or extended warranty, the initial setup must follow strict engineering guidelines:

• Certified Installation: Commissioning into service must be undertaken by an authorised Excel Power dealer or a competent, independent generator engineer.
• Documentation: A formal commissioning certificate must be issued at the time of setup.
• Important Policy: The warranty will be deemed completely void if this professional commissioning is not completed and documented.

Extended Warranty Option (2 Years / 2,000 Hours)

You can increase your coverage to a 2-Year / 2,000-Hour Limited Warranty by signing a continuous service contract with an authorised Excel Power dealer.

To maintain eligibility for this extended coverage, the service contract must meet the following criteria:

• Timeline: The service contract must commence immediately at the time of the generator’s commissioning.
