Pramac PMi4500 4.2kW Electric Start Petrol Inverter Generator
The Pramac PMi4500 HUK combines 3.8kW rated output with 4.2kW maximum power, electric and recoil starting, and inverter regulation. A 12-litre tank, integrated wheels and two UK 13A sockets make it a flexible outdoor supply for leisure, work and backup applications.
Key Features
- 3.8kW rated output and 4.2kW maximum output at 230V, 50Hz, single phase.
- Inverter regulation provides stable output for compatible electronic equipment.
- Electric starting with recoil backup, plus remote-control, two-wire start and ATS connection capability.
- Economy Mode adjusts engine speed to suit demand.
- Integrated wheel kit and fuel gauge for easier handling and fuel checks.
- Up to 9.7 hours at 50% load in Eco Mode from a 12-litre petrol tank.
Where to Use
Suitable for outdoor events, caravanning, light work and selected household loads during an outage. Its two-wire start and ATS connection capability also allow it to be considered for a professionally designed backup system, subject to control compatibility.

Backup and Automatic Starting
- An ATS panel and any required external control wiring are separate from this generator listing.
- Two-wire starting must be checked against the connected inverter or controller before installation.
- Automatic backup requires compatible controls, correct siting and a professionally installed transfer arrangement. The ATS connector alone does not provide an automatic home-backup installation.
- Use the 3.8kW rated output for sustained-load planning; allow additional headroom for starting motors.
Generator Safety
Operate outdoors only, well away from doors, windows and air intakes. Exhaust contains carbon monoxide. Never run the generator inside a home, garage, tent or other enclosed or partly enclosed space. Allow the engine to cool before refuelling. Read the operator’s manual before use. Any connection to building wiring must be designed and installed by a qualified electrician with a suitable changeover arrangement to prevent backfeeding.
