P1 P4000i 3800W Portable Petrol Inverter Generator

The P4000i is a compact yet powerful portable inverter generator powered by the Hyundai IC225D 4-stroke single cylinder air cooled engine, providing a reliable power source.

Portable Power

Producing a maximum power of 3800w / 3.8kW and continuous power of 3600w / 3.6kW, the P4000i is ideal for caravans and motorhomes as it allows you to take the modern luxuries from home with you wherever you go.

Easy To Transport And Store

The P4000i symmetrical design allows you to store it easily and transports in the back of a van or car. Weighing only 48kg and measuring just 630x400x520mm, and with the folding front handle and fixed rear handle plus heavy duty rear wheels makes transportation easy across a variety of surfaces.

Suitable For Power Tools

It houses a new inverter board designed to cope with the extreme inductive loads applied when using power tools and electric motors with high startup currents.

New Display 

The new LCD display makes it easy to monitor the performance of the generator, displaying voltage, frequency and hour count.

Variety Of Uses

The control panel features two 230v sockets for use with any appliance which use a standard 3-pin 13A UK mains plug, as well as a 12v DC battery charging outlet and a USB port for charging mobile phones and ipads. It’s ideal for a variety of uses. 

Clean Power

Producing a pure sine wave output is ideal for powering most electronic equipment.

User Friendly

The P4000i inverter generator is extremely popular for large motorhome use and it’s built to be user-friendly with low maintenance requirements.

Safety Features

Digital overload protection will shut the generator down should the load pass the maximum threshold, and low oil shutdown also turns off the generator should the oil levels drop too far.

ECO Mode

Already an economical generator, the P4000i also has the added benefit of an “ECO” mode which, when selected, will lower the engine revs to match the load being applied, which in turn increases the fuel economy, lowers the noise produced and extends the lifespan of the engine.

    Awesome generator

    Posted by Mike H on 19th Mar 2021

    Just received new P1 4kw generator. Absolutely brilliant bit if kit. Used bog std open frame gens until now and it’s it’s like chalk and cheese in comparison. You just fill with supplied oil 600ml and using screw in oil filler neck so no mess. Add fuel and the supplied fuel stabiliser so fuel doesn’t stagnate if gen not used often. Connect the battery plug turn on and press start. It’s that easy. Started on first press of starter and every time after. Oh and telescopic handle is brilliant too Highly recommended you won’t be disappointed with this purchase

    P400i inverter generator

    Posted by MD Bromsgrove on 30th Dec 2020

    Very good quality generator with many features not included on other sets. The most impressive feature is the quietness, at 53db it is incredibly quiet. You can have a conversation with the generator running without having to raise your voice! Secondly it is very fuel efficient, with the added feature of an accurate readout of time left according to fuel and load. Expensive compared to other options, but worth it.
