Xantrex Technology 150 - Manual (Page 18)

14
Measured inverter output voltage is too low.
Symptom The AC voltmeter reading is 5 to 15 volts too low.
Battery operating time is less than expected.
Symptom The inverter runs for a while, and then the
light comes on. The inverter is cool or warm to touch.
Possible cause Suggested remedy
The lighter socket or the 12 volt
outlet may require that the
ignition be switched on. Turn the key to the accessory
position.
The cigarette lighter fuse or the
12 volt outlet fuse is blown. Check the vehicle fuses, and
replace the blown fuse with the
correct type and size.
Possible cause Suggested remedy
A standard “average reading”
AC voltmeter has been used to
measure the output voltage. For accuracy, the 150 Inverter
modified sine wave output
needs to be measured with a
“true RMS” voltmeter, like a
Fluke 87 series multimeter.
The battery voltage is too low. Recharge the battery.
Possible cause Suggested remedy
The battery is old or defective. Replace the battery.
The battery is not being charged
properly. Have a qualified technician
check the vehicle’s electrical
system.
