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.
P/No.
AC Combined maximum load (Watts)
AC Combined maximum 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 power
supply is required, typically a vehicle or caravan battery, portable power pack or
an independent 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 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.
