or 1000 Watt inverter may be needed.
•
Capacitive loads such as many TV's or many electronic appliances (desktop computer,
monitor etc.) require a large surge current to start only when they have not been used
for a while. This is often due to large capacitors in the switched mode power supply
that must be quickly charged when the appliance is turned on. If the appliance has not
used for a while these capacitors slowly go flat. If the inverter trips on overload then
restarting a few times may allow these appliances to work.
•
There are some appliances such as large refrigerators, air conditioners and other
compressor driven appliances that have extremely high startup currents, because
they have an electric motor that must start under load. These appliances are not
recommended for use with an inverter. However check with the manufacturer as
motors with "soft-start" capability may be capable of being used with an inverter.
Q. The inverter is powering my portable television, but I cannot get a clear picture?
A. In poor reception areas it is quite common to have some interference on a portable TV
(such as faint lines on the screen) when operating on all modified sine wave inverters.
•
To improve your picture quality:
-
Keep the inverter as far away from the TV as possible.
-
Use an external long range or fringe area TV antenna with good quality coax cable.
-
Earth (using Chassis GND) the inverter (see the section on Earthing)
Q. Can I run fluorescent lighting from my inverter?
A. Most portable fluorescent work lamps should operate fine on an inverter even
though they may be slow to start.
•
Fluorescent lights are an inductive and capacitive load and often draw at least
twice as much power from the inverter than their normal rating during start up.
•
Normal household fluorescent lights should be avoided, because they contain power
factor correction capacitors. Power factor correction is used in buildings installations
to help smooth out the inductive effects of fluorescent light ballasts. If used with
portable power inverters the power factor correction is effected by the harmonic
distortion in the modified waveform, this causes a high load on the inverter that can
overload the unit. If normal household fluorescent lights must be used, you will need
to have a qualified electrician remove the power factor correction capacitor. The light
should then be marked

For Inverter Use only

. Or simply use a fluorescent light with
an electronic ballast!
Q. Why does it damage the inverter if the battery leads are connected in reverse?
A. Your inverter uses sophisticated electronics to convert DC battery power to AC
mains power. If you accidentally connect the inverter to the batteries incorrectly
(reverse polarity) a large current will be drawn by the inverter which will blow the
protection fuses, as this occurs some of the high current could damage sensitive
electronic components. Because of this risk it is important to always double-check
the batteries polarity before making the input connections.
