- Powerful with big power outputs, 18.5hr run time
- 115 or 230v
- AC and DC
- Portable using wheelbarrow style handle
After experiencing the CAT RP 4400 Low Power Generator Set, I now have a more flexible interpretation of portable. Once the wheels are added, the CAT does indeed become portable. One person, even me with a slightly bad back, can easily wheel it about and get it up a few steps and through a standard doorway. Clearly this is enough portability for its intended use on worksites, and where back-up power is needed. The wide treaded never-flat wheels are big enough to allow it to be manoeuvred over even softer surfaces like grass and unmade paths.
The RP4400 is the most powerful genset in a small series of three machines that are intended to cover a range of demands from small users for serious power in workplaces, on smallholdings and back-up power for the home.
With its maximum output of 4400W the CAT will power anything from TVs to power tools, so it is really flexible.
Powered by a modern and reliable 300cc four stroke engine that will produce the required power at a pretty unstrained noise and 3000 RPM rev level, it is also quiet enough that it won’t deafen you even when you are quite close to it.
The genset produces AC voltage of 115 or 230v at 50Hz frequency, and it has AVR or Automatic Voltage Regulation that is needed for the safe use of modern electrical equipment.
According to the specs, a full tank of fuel should last up to 18.5 hours – enough to get you through a full dark night in Scotland in midwinter. Filling the tank is easy since the fuel cap and tank are located on the top of the machine. Removing the metal cap reveals a fuel filter – an absolute necessity when filling from fuel containers that can be more easily contaminated with sediment etc. The fuel gauge, also on top of the tank, gives an adequate reading of the fuel available.
Handily, all the controls and power outlets are located on one end of the generator.
The controls are simple and self-explanatory, and a handy quick guide is mounted on the fuel tank for easy reference and is also supplied with the comprehensive instruction booklet. I guess it would be a good idea to keep it in its plastic bag and keep it near the generator at all times. (All manuals are also available as PDF download from www.cat.com/homeandoutdoor)
On the other side of the machine is a foldable, two-position tubular steel handle. This can be locked into its positions with a pin. The handle and the wheels are the keys in making the RP4400 portable. Acting like wheelbarrow handles, the weight of the machine is largely over the wheels, so it is easier to move.
Examining the frame revealed that it is a simple, but very strong space frame, made from steel tubing welded together. It provides a solid base on which to attach the motor and generator, as well as providing good protection for the vital bits when it encounters the inevitable bumps and bangs of the work site.
I guess you could still use this generator as a portable power source at a craft fair – but it would be at home powering several stalls and even more lights. And in winter maybe even powering a heater or two for stallholders.
