6.2 Overload
The status LED will be orange and will come on when the power inverter has shut itself
down because its output circuit has been short circuited or drastically overloaded. Switch
the ON/OFF switch to OFF, correct the fault condition, and then switch the ON/OFF switch
back to ON.
Some induction motors used in refrigerators, freezers, pumps and other motor operated equip-
ment require very high surge currents to start. The power inverter may not be able to start
some of these motors, even though their rated current draw is within the power inverter.
If the motor refuses to start, observe the battery voltage indicator while trying to start the
motor. If the battery voltage indicator drops below 11 volts while the inverter is attempting to
start the motor, this may be why the motor will not start. Make sure that the battery connec-
tions are good and that the battery is fully charged. If the connections are good and the
battery is charged, but the voltage still drops below 11 volts, you may need to use a larger
battery.
6.3 Input voltage
The power inverter will operate from input voltage ranging 10 V – 15 V. If the voltage drops
below 10.7 V, an audible low battery warning will sound and the status LED will be orange.
The power inverter will shut down if the input voltage drops below 10 V. This protects your
battery from being over discharged.
The power inverter will also shut down if the input voltage exceeds 15 V. This protects the
inverter against excessive input voltage. Although the power inverter incorporates protection
against overvoltage, it may still be damaged if the input voltage is allowed to exceed 20 V.
7. Troubleshooting
7.1 Common problems
a) Buzz in audio systems
Some inexpensive stereo systems will emit a buzzing noise from their loud speakers
when operated from the power inverter. This is because the power supply in the device
does not adequately filter the modified sine wave produced by the power inverter. The only
solution is to use a sound system that incorporates a higher quality power supply.
b) Television interference
Operation of the power inverter can interfere with television reception on some channels.
If this situation occurs, the following steps may help to alleviate the problem.
• Make sure that the chassis ground lug on the back of the power inverter is solidly
connected to the ground system of your vehicle, boat or home.
• Do not operate high power loads with the power inverter while watching
television.
• Make sure that the antenna feeding your television provides an adequate
(“snow free”) signal and that you are using good quality cable between
the antenna and the television.
