Radio Frequency Interference
For many years, Radio Frequency Interference (RFI) has been an annoying
problem for owners of Inverters. RFI in a domestic situation can cause noise
on an AM radio receiver. The degree of interference can vary dramatically
from site to site. Below are a few suggestions to help reduce the effects of
RFI in your installation. It is not essential that you follow these guidelines,
however, they will give you the best chance of reducing any RFI, particularly
on AM radio.
It is recommended that the power system including the inverter be housed at
least 10 metres from the home.
Ensure a good earth stake is placed as close to the inverter as possible. This
earth stake should be in a moist area and should be connected to the inverter
earth, see page 2 for wiring details.
Avoid running DC cables into the home, if at all possible. If this cannot be
avoided, run DC and AC in separate conduits separated by as much distance
as practicable. All DC wiring should also be kept as short as possible.
Connect battery negative to earth.
AM radios should be powered from their own self contained batteries and
kept as far away as possible from AC or DC wiring within walls. Make sure
that your AM radio has maximum signal strength. This will help your radio
to reject any unwanted noise being produced by your inverter, regulator,
controllers or DC lighting. If possible, try moving the radio around to
improve the signal strength or use an external aerial. Some of today's
building materials such as steel roofs and foil insulation may form a barrier
to incoming radio signals. If an external aerial is required, it should be on the
outside of the home, mounted as high as practicable and as far from the
inverter as possible. Connection from the aerial to the radio should be via a
low loss coaxial cable.
Please note
the aerial must be an AM RADIO type; a TV aerial will
not work.
