Thissection provides you with basic information about
theinverter and how to check its performance before
installation.
Besure to haveon hand:
A12 volt DC power source (such as a vehicle battery).
Thepowersource mustprovide
between11and 15 volts DC and be
ableto supply enough currentto
runthe test load. As a rough guide,
dividethe wattage of the test load
by10 to get the current(in amperes)
thepowersource mustdeliver.
Aset of cables to connect the power source to the
inverter(not included).
Thecables must be as short and thick as possible in
orderto reduce the voltage drop between the power
sourceand the inverter when drawing current from
thepower source.
Ifthe cable suffersan excessive voltagedrop, the inverter
mayshut down when drawing higher currents because
thevoltage at the inverter dropped below 10 volts.
#4AWG stranded copper cable is recommended. It
shouldbe no longer than four feet (one and one-half
meters).
Theend of the cable that connectsto the inverter must
haveits insulationstrippedoff for about one-halfinch (one
andone-halfcm) back from the end,exposing the bare
copper.
Theother endof the cable, whichconnects to the power
source,mustbe terminatedwith a lug or other connector
thatprovidesa secure, low resistanceconnection.
Forexample, if the power source is a battery, the cable
mustbe terminated with a battery terminal that clamps
tothe post on the battery.
