Draper Petrol Open Frame Inverter Generator, 2800W

The Draper PG3000DI is a professional open frame inverter generator purpose-built for demanding commercial environments where power quality matters as much as power quantity. Producing a rated output of 2,800W (3.5kVA) and a peak of 3,200W (4.0kVA), this generator uses pure sine wave inverter technology to deliver clean, stable electricity that's safe for sensitive electronics, variable-speed power tools, and modern site equipment.

Driven by a proven 196cc forced air-cooled four-stroke OHV engine outputting 6.5HP, the PG3000DI runs for a full 5 hours at 100% load from its 5-litre fuel tank – one of the longest continuous run times in its class. At just 26kg and fitted with two large rubber wheels, it's notably lighter and more manoeuvrable than comparable generators, making it an excellent choice for equipment hire fleets and contractors who move sites regularly.

Key Features & Benefits

Pure Sine Wave Inverter Technology

Unlike conventional generators that produce a modified or stepped waveform, the PG3000DI outputs a pure sine wave – the same smooth, consistent waveform supplied by the National Grid. This makes it safe to run sensitive electronics including computers, battery chargers, variable frequency drives, LED lighting systems, and modern inverter-driven tools without risk of damage or malfunction. For commercial hire and mixed-load site use, this is an essential feature.

High Rated Output – 2,800W Continuous

With a rated output of 2,800W (3.5kVA) and a maximum peak of 3,200W (4.0kVA), the PG3000DI has the headroom to handle multiple tools simultaneously – angle grinders, circular saws, site lighting, battery chargers, and more – all from a single unit.

Twin 230V Sockets

Two 230V 13A sockets allow two pieces of equipment to run at once without the need for an extension lead block, reducing trip hazards and cable clutter on site. Both sockets deliver the same clean inverter output.

Dual USB Charging (5V DC)

Two 1.0A USB ports provide convenient charging for smartphones, tablets, GPS devices, and other USB-powered equipment – a practical touch that eliminates the need for separate adapters or power banks on longer jobs.

5-Hour Runtime at Full Load

The 5-litre fuel tank delivers an impressive 5 hours of continuous operation at 100% load – well above average for a generator in this power class. That's a full working day from a single fill-up at moderate loads, significantly reducing downtime and fuel handling on site.

Lightweight and Wheeled for Easy Mobility

Weighing just 26kg and fitted with two large, robust rubber wheels, the PG3000DI is among the most portable generators in the 2800W class. Move it between work areas, load it in and out of vans, and position it on uneven ground with minimal effort – a real advantage for sole traders and small teams working without lifting equipment.

196cc 4-Stroke OHV Engine

The high-quality 196cc forced air-cooled four-cycle overhead valve petrol engine delivers 6.5HP of reliable power. OHV technology provides better thermal efficiency, cleaner combustion, and lower long-term running costs than older side-valve designs.

Easy Pull Recoil Start

A well-designed recoil start mechanism gets the engine running quickly and reliably without the added weight, cost, or maintenance demands of an electric start system.

Heavy-Duty Steel Tubular Frame

The open frame design wraps the engine and alternator in a robust steel tubular chassis, protecting internal components from impact damage during transit and on busy sites. Oil and fuel resistant anti-vibration mounts further reduce mechanical stress and operator fatigue.

E5 and E10 Fuel Compatible

Fully compatible with E10 unleaded petrol – the standard grade now dispensed at the majority of UK forecourts – so there's no need for specialist fuel or additives. E5 compatible too for use where E10 is unavailable.

Who Is the Draper PG3000DI For?

Equipment Hire Fleets – Lightweight, durable, and compatible with the widest range of modern tools and electronics. The pure sine wave output reduces the risk of hire customer equipment issues, and the wheeled frame makes handling easy for depot staff and end users alike.

Construction & Groundworks Contractors – Power multiple 230V tools simultaneously from a single generator. The 5-hour full-load runtime keeps jobs moving without constant refuelling stops.

Electrical & HVAC Trades – Pure sine wave output is essential for running modern inverter-driven tools, diagnostic equipment, laptops, and chargers without interference or damage risk.

Outdoor Events & Film/TV Production – Clean power for PA systems, cameras, lighting rigs, and catering equipment where a dirty waveform could cause hum, interference, or equipment failure.

Agricultural & Rural Operations – A reliable, fuel-efficient power source for remote locations where mains power isn't available and equipment sensitivity matters.

Emergency & Disaster Recovery – Safe, stable power for medical devices, communication equipment, and sensitive electronics during mains power outages.

Frequently Asked Questions

What is pure sine wave output and why does it matter? Pure sine wave output replicates the smooth waveform of mains electricity. Many modern devices – including laptops, phone chargers, variable-speed tools, LED lighting, and medical equipment – require this type of waveform to operate safely and efficiently. Standard (non-inverter) generators produce a rougher waveform that can cause overheating, reduced performance, or damage to sensitive equipment. The PG3000DI's inverter technology eliminates this risk.

What fuel does the PG3000DI take? The generator runs on standard unleaded petrol and is compatible with both E5 and E10 fuel – widely available at UK forecourts.

What oil does the PG3000DI use? SAE 10W-30 engine oil is recommended, with a capacity of 0.6 litres. Always check the oil level before first use and before each start. Oil is available separately.

How long will it run on a full tank? The 5-litre tank provides 5 hours of continuous operation at 100% load. At more typical partial loads, runtime will be longer.

How does the PG3000DI compare to a standard (non-inverter) generator? The key difference is power quality. Inverter generators like the PG3000DI produce a stable pure sine wave output, making them suitable for sensitive electronics. They also typically run more quietly and efficiently at partial loads. The trade-off is a slightly higher purchase price – offset by greater versatility and lower risk of equipment damage.

Is the PG3000DI suitable for a UK construction site? The PG3000DI outputs 230V only – it does not have a 110V CTE output. For sites where 110V CTE tools are mandatory, consider the Draper PG252F which offers both 110V and 230V outputs. The PG3000DI is ideal for sites using 230V tools or where power quality for sensitive equipment is the priority.

How heavy is it and is it easy to move? At 26kg with two large integrated rubber wheels, the PG3000DI is one of the most manoeuvrable generators in its power class and can be moved by one person across most surfaces.
