TROUBLESHOOTING / FAQ:
Q. Why does the inverter turn itself off?
A. If the inverter makes a beep sound and the “RED” fault light illuminates this indicates that there
is a problem, and the inverter will usually turn off. Most commonly this would be caused by an
appliance that is drawing too much power (overloading), low battery voltage or voltage drop due
cient size cables or poor connections (see section on protection features, page 12).
Q. The inverter will not run my appliance even though the appliance draws less power
(Watts) than the size of the inverter?
A. Electrical appliances can be divided into three groups by the way they draw energy (current) from
their power supply. These groups are “Resistive”, “Inductive” and “Capacitive” appliances or also
called “loads”. Some appliances may draw all three types of power.
(watts) from the power supply, that is a 100 Watt light will draw approximately 100 Watts from
the power supply at all times. Resistive loads are the easiest appliances for an inverter to run.

to start and then usually draw a more constant power once running. Inductive loads contain coils

- The most common inductive appliances are: fridges, air compressors, transformers/chargers,
uorescent lights. These appliances can draw 2 - 6 times their normal
running power to start up, that is to run a 190 Watt fridge you may need a 600 or 1000
Watt inverter.

may allow these appliances to work.
UÊ There are some appliances such as large refrigerators, air conditioners and other pump driven
appliances that have extremely high start up currents, because they have an inductive motor that
must start under load. These appliances are not recommended for use with an inverter. They
should be powered by an engine driven generator.
Q. The inverter is powering my portable television, but I cannot get a clear picture?
