GENERATOR GUIDELINES
• Lack of regular servicing can be the cause
of most generator problems, gensets
under 2kW are mainly dependent on
engine speed for output frequency and
voltage. Poor or no servicing may cause
the engine speed governor to run the
genset to fast. Therefore, frequency and
output voltage can rise above the
specification of the machine data plate i.e.
230V at 50Hz. This may cause damage to
electrical/electronic equipment (such as
battery chargers).
• A generator should always run for a few
minutes prior to connection with the
motorhome electrics, to allow it to warm
up and the output to settle to a steady
level.
• The AC output of generators is often
derived from an AC alternator, rectified to
DC then inverted back to AC. In essence
this means the output sinewave may not
run sophisticated electronics efficiently.
Some of the new wave of gensets are
more sophisticated in their production of a
sinewave output and are more suited to
run electronic equipment.
• If in doubt consult your genset dealer or
manufacturer for advice
