Problem Possible Cause Solution
Low output voltage (96 VAC–104 VAC) You are using a voltmeter that cannot
accurately read the RMS voltage of a
modified sine wave.
Low input voltage and the load is close to
maximum allowable power.
Use a true RMS reading voltmeter such as the
Fluke 87.
Check the connections and cable to see if the
battery is fully charged. Recharge the battery
if it is low.
Reduce the load.
No output voltage. Both the Power Light and
Fault Light are off.
The inverter is off.
No power to the inverter.
The inverter could have been connected with
reverse DC input polarity.
Turn the inverter on.
Check the wiring to the inverter and to the
battery selector switch (if installed).
The inverter has probably been damaged.
Return the unit. Damage caused by reverse
polarity is not covered by the warranty.
Information for returning the inverter is
provided in “Return Procedure” on page 23.
No output voltage. Power Light is on. GFCI is tripped. Reset GFCI. See “Testing the GFCI” on page
14.
