This section provides you with basic information about
the inverter and how to check its performance before
installation.
Be sure tohave on hand:
A 12 volt DC power source (such as a vehicle battery).
The powersourcemustprovide
between11 and 15volts DC and be
able to supply enough current to
run the test load. As a rough guide,
divide the wattage of the test load
by 10 to get the current (in amperes)
the powersourcemustdeliver.
A set of cables to connect the power source to the
inverter (not included).
The cables must be as short and thick as possible in
order to reduce the voltage drop between the power
source and the inverter when drawing current from
the power source.
If the cable suffersan excessive voltage drop, the inverter
may shut down when drawing higher currents because
the voltage at the inverter dropped below 10 volts.
#4 AWG stranded copper cable is recommended. It
should be no longer than four feet (one and one-half
meters).
The end of the cable that connects to the inverter must
have its insulationstrippedoff for about one-half inch (one
and one-half cm) back from the end, exposing the bare
copper.
The other end of thecable,which connects to the power
source, must be terminated with a lug or other connector
that provides a secure, low resistanceconnection.
For example, if the power source is a battery, the cable
must be terminated with a battery terminal that clamps
to the post on the battery.
