UNDERSTANDING YOUR POWER REQUIREMENTS
POWER REQUIREMENTS OF YOUR APPLIANCE/S:
All appliances have a rating plate that shows the amount of power (Watts) used or the current
(Amps) drawn under normal use.
The following table shows the maximum combined AC Watts or AC Amps which can be run by
the inverter.

load (Amps)
Some appliances that use an electric motor or transformer may draw up to 10 times their power
rating when first turned on. These are called inductive loads and are the most difficult for the
inverter to run. Contact your appliance manufacturer for further advice.
SUITABLE POWER SOURCE
In order to operate the inverter and supply power to an appliance a suitable 12V DC power supply
is required, typically a vehicle or caravan battery, portable power pack or an independent 12V lead
acid battery. For most applications, a deep cycle battery is recommended for best performance.
The size of the battery used will determine how long the inverter will supply power to an
appliance and how well the inverter will perform. Most batteries are marked with their size in
Amp hours (Ah) or Cold Cranking Amps (CCA).
Because 12V inverters are capable of drawing high currents the inverter should only be connected
to a suitable size battery. Connection to an undersized battery could damage the battery and will
result in the inverter shutting down within a short period due to low battery voltage.
The amount of power drawn from the battery is proportional to the inverter load.
