2. Over Temperature Shut Down
Your inverter will safely provide the output power defined in the technical data section under the conditions specified.
If the Inverter shuts down and indicates over temperature, it may be that you have exceeded one of the parameters.
Check the following:
•
Ensure the Inverter has adequate ventilation. Insufficient ventilation can severely restrict the power output of your
Inverter as it does not allow proper heat dissipation.
•
Ensure that the true power rating of your appliance (including power factor) is less than the output rating of your
Inverter.
3. Shut Down When Trying to Start a Load
A sudden surge in load, such as a motor starting, may cause the inverter to shut down. If this occurs:
•
Ensure the battery voltage is within specifications when the device is trying to start. If the input voltage drops too
low, you may need to increase the capacity of your batteries. Also check DC cables and terminations.
•
If the battery voltage is ok when measured at the Inverter, then the Inverter AC output power rating may be too.
4. Overload Shut Down
The overload indicator indicates that the Inverter has shut down. If this occurs:
•
Ensure the output circuit is not 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’.
5. Under Voltage Shut Down
The under voltage indicator indicates that the Inverter has shut down because the protection circuits have sensed the
DC input voltage is lower than that recommended for safe operation. If this occurs:
•
Charge the battery.
•
Check the battery voltage at the terminals of the Inverter is within specification. If the input voltage drops too low,
you may need to increase the capacity of your batteries. Also check DC cables and terminations.
6. Over Voltage Shut Down
The over voltage indicator indicates that the Inverter has shut down because the protection circuits have sensed the DC
input voltage is higher than that recommended for safe operation. If this occurs:
•
Check the DC power source or battery voltage at the terminals of the Inverter is within specification.
7. Television
Interference
Operation of the Inverter can interfere with television reception on some channels. If this occurs, the following steps
may help alleviate the problem:
•
Make sure that the chassis ground lug on the back of the Inverter is solidly connected to the ground system of
your vehicle, boat or home. Make sure there is no oxidation or corrosion on any groumd terminations.
•
Try not to operate high power loads with the Inverter while watching television.
•
Make sure that the antenna feeding your television provides an adequate (“Snow free”) signal and that you are
using high quality shielded cable between the antenna and the television.
•
Move the television as far away from the Inverter as possible.
•
Keep the cables between the battery and the Inverter as short as possible. Twist them together with about 6 to 9
twists per metre as this helps minimising radiated interference from the cables.
