MAC AFRIC 6.5KvA (5 KW) Standby Enclosed Type Diesel Generator – 380V Three Phase

An electrician is required to conduct a load-test to ensure you can make an informed purchase decision that is based on your needed amperage per phase.

Generators are manufactured to run at 80% of its maximum output when at sea-level and in a neutral climate. Factors such as altitude and temperature can affect the efficiency of your engine therefore, creating less power.

Limitations of use:

Do not use of more than 50% of your generator’s rated load for your “first step load”.
Do not use of more than 75% of your generator’s rated load for your “Running load”.

These limitations are set to account for any spikes or drops in current that naturally occur in the combustion process of fuel powered generators.

Power output – 5KW (6.5kVa) (1.6KW per phase)
Rated voltage – Three Phase (380V)
Current Output – 7.6A (per phase)
Fuel consumption – 1.67 l/ph @ full load
Tank capacity – 15 litres
Dimensions – 910 x 520 x 740mm
AVR – AVR fitted
Weight – 171kg
Oil capacity – 1.65 litres
Sound level – 75 db(A) @ 5M

Factors to consider when buying a generator.

WARNING:

THIS GENERATOR MAY NOT RUN AT LESS THAN 40% OF ITS RATED OUTPUT FOR MORE THAN 1 HOUR CONTINUALLY!

Engine glazing can cause major problems in generator sets when they’re too lightly loaded.

This is often caused by the generator not being sized correctly in the first place. It is critical that a generator is sized correctly especially when the load is constantly the same, to prevent glazing and also to be fuel efficient.
Operating diesel engines at light loads for extended periods of time can cause glazing to the cylinder bores. This occurs because poor combustion can lead to soot formation and unburnt fuel residue which clogs & gums up piston rings which causes the piston rings to not seal as well. Glazing of the cylinder bores occurs when hot combustion gases blow past the now poorly sealing piston rings and creates a glaze on the cylinder bore & increased oil consumption. This can lead to oil entering the exhaust, heavy carbon build up on: pistons, piston rings & ring grooves, valves & valve guides, cylinder head ports & exhaust pipes, and turbocharger seals on turbo charged engines.

If left unchecked, the engine can be damaged to point where it has to be rebuilt or replaced.
