Stephill 5000HMS 5kVA Petrol Generator: Robust Power for Demanding Sites
The Stephill 5000HMS is a heavy-duty, open-frame petrol generator designed and manufactured in the UK to meet the rigorous demands of the construction and hire industries. Delivering a powerful 5.0kVA (4.0kW) output, it's an ideal portable power solution for powering a wide range of hand tools, site equipment, lighting, and small machinery on construction sites, remote locations, or during power outages. Its core strength lies in the combination of a reliable Honda engine and a durable, British-made Stephill alternator and frame.
Features
- Reliable Honda GX270 Engine: At the heart of the 5000HMS is the industry-renowned Honda GX270 9.0HP, 270cc 4-stroke petrol engine. These engines are known for their exceptional reliability, fuel efficiency, easy starting (recoil start as standard), and long service life in tough conditions.
- Robust 5.0kVA / 4.0kW Output: Provides ample power for a variety of demanding applications. The 4.0kW continuous rated output ensures stable power supply for sensitive equipment.
- Dual Voltage Capability: Equipped with a voltage selector switch, offering both 230V (2 x 16A sockets) and 115V (1 x 16A & 1 x 32A sockets) industrial BS4343 sockets, making it compatible with a wide range of site equipment.
- Heavy-Duty Brushless Alternator: Features a high-quality NSM K100F brushless, smooth waveform alternator. This provides a stable and clean power output, suitable for running sensitive electronics, and is maintenance-free.
- Rugged Construction (Hiremax Range): Built to withstand tough environments. It features a full wrap-around, heavy-duty tubular steel frame with strong anti-vibration mounts for the engine and alternator, ensuring durability and vibration dampening.
- Metal Control Box: Houses the sockets and controls in a robust metal enclosure, offering enhanced protection against knocks and environmental factors on site.
- Safety Features:
- Oil Alert / Low Oil Shutdown: Automatically shuts down the engine if oil levels drop too low, preventing costly engine damage.
- Reset Circuit Breaker Overload Protection: Protects the generator and connected equipment from damage due to overload.
- Compact & Portable: Despite its robust build, it has manageable dimensions (L690 x W480 x H540mm) and a dry weight of approximately 59 kg, making it relatively easy to transport around site.
- Decent Run Time: Comes with a 5.3 to 6.0-litre fuel tank (sources vary slightly, typically 5.3L). This provides a run time of approximately 2.7 to 3.5 hours at 75% load, depending on the exact fuel tank fitted. Optional long-run metal tanks (15-litre) are available for extended operation.
- Quiet Operation: Offers a relatively low noise level for an open-frame petrol generator of this size, typically 72 dBA @ 7 metres.
- UK Manufactured: Stephill Generators are proud of their British manufacturing, ensuring high standards of quality and component sourcing.
- Noise Level: 72 dBA @ 7 metres
- Dimensions (L x W x H): 690 x 480 x 540 mm
- Weight (Dry): Approx. 59 kg
Applications
The Stephill 5000HMS is ideal for a wide range of portable power requirements:
- Construction Sites: Powering site tools (saws, drills, grinders, mixers), lighting towers, and small welfare units.
- Emergency Power: Providing temporary power for essential equipment during power outages.
- Outdoor Events: Supplying power for small stages, catering, or lighting.
- Agricultural Use: Powering tools and equipment in remote farm locations.
- General Tradesman Use: For builders, roofers, landscapers, and general contractors requiring mobile power.
Standards & Compliance
Stephill Generators are manufactured to high standards and comply with relevant regulations:
- CE Marking: Conforms to applicable European Directives (e.g., Machinery Directive 2006/42/EC, Electromagnetic Compatibility Directive 2014/30/EU).
- ISO 8528-1: Applicable for supplying power to varying electrical load for unlimited hours in accordance with this standard.
- Noise Emissions: Designed to comply with relevant noise regulations for generators (indicated by the dB(A) @ 7m rating). Hearing protection is still recommended during operation.
