Stephill 5000HMSLR 4.0kW Long-Run Petrol Generator 230V/115V | Honda GX270

The Stephill 5000HMSLR 4.0kW Long-Run Petrol Generator is engineered for demanding construction, equipment-hire, industrial and professional site applications.

Delivering a continuous and maximum output of 5.0kVA / 4.0kW, it combines dependable Honda power with a heavy-duty hire specification, versatile dual-voltage outputs and an extended-running fuel tank.

Designed and manufactured in the UK, the 5000HMSLR provides reliable and cost-effective portable power for professional users working in demanding environments.

Honda GX270 Stage V Petrol Engine

The generator is powered by a dependable Honda GX270 four-stroke petrol engine.

Honda GX engines are widely recognised for reliable starting, fuel-efficient operation and long service life. The engine complies with EU Stage V emissions requirements, making it suitable for modern construction and commercial applications.

Honda’s low-oil shutdown system automatically stops the engine if the oil level falls below a safe operating point, helping protect it against avoidable damage.

Dual 230V and 115V Outputs

The Stephill 5000HMSLR is equipped with:

• 1 × 115V 16A socket
• 1 × 115V 32A socket
• 2 × 230V 16A sockets
• Voltage-selector switch

This flexible socket configuration allows the generator to power reduced-voltage professional site tools alongside standard 230V equipment.

The available power through each socket is limited by its voltage and current rating. Additional allowance should be made for motors, pumps, compressors and other equipment with increased starting requirements.

Heavy-Duty Hire Specification

The 5000HMSLR is designed to withstand frequent transportation and challenging site conditions.

Its heavy-duty construction includes:

• Reinforced full wrap-around frame
• Twin-mounted alternator
• Rugged metal control box
• Heavy-duty skid base
• Anti-vibration mountings
• Protected engine and electrical components

These features help improve durability and operating stability during professional use.

Heavy-Duty Alternator

The Honda engine is close-coupled to a heavy-duty alternator mounted at two points for improved strength and stability.

The generator is supplied without Automatic Voltage Regulation as standard. An AVR-equipped version may be available as an optional configuration where enhanced voltage control is required.

Long-Run Fuel Tank

The integrated 15.5-litre petrol tank provides up to approximately 8 hours of operation at 75% load.

This extended runtime makes the generator suitable for longer working periods where regular refuelling would be inconvenient.

Actual runtime will vary depending on the connected load, operating conditions and generator maintenance.

Portable Professional Design

The generator weighs approximately 67kg and is designed for transport between sites and working locations.

A trolley or wheel kit may be available to improve mobility. The supplied information refers to a trolley kit as part of the generator’s portability equipment but also lists a wheel kit as an optional extra, so the exact supplied configuration should be confirmed when ordering.

Optional Extras

Available options may include:

• Electric-start system
• Automatic Voltage Regulator
• Wheel or trolley kit

Optional equipment and factory configurations should be confirmed before ordering.
