Acoustics buzzer alarms
When applying the inverter to acoustics devices, some inferior acoustics
devices will buzz, this is because the output wave from the inverter is modified
sine wave inverter�
TV Interference
You can get minimum interference through use of a filter� On some occasions,
when the interference of every weak signals becomes too obvious, you can try
the following:
• Place the inverter far from the TV and TV antenna�
• Try to change the direction of TV signals cable and TV antenna to reduce the
interference to minimum�
• Use screen cable antenna of highly quality�
Problem: No output voltage
Possible Causes
Solution
Battery voltage too low Recharge or replace the battery
Overload Reduce the load
Inverter thermal protection Cool the inverter and place it in the
place with good ventilation; Reduce
the load�
Inverter start-up fail Repeat starting the inverter
Reverse polarity connection and fuse
melted Replace the fuse with a fuse of equi-
valent value�
Problem: Inverter no response
Possible Causes
Solution
Poor contact between battery and
inverter Reconnect them
Reverse polarity connection and fuse
melted Replace the fuse with a fuse of equi-
valent value�
Problem: Output voltage low
Possible Causes
Solution
Input voltage too low Make sure input voltage is within the
rated range�
Overload Reduce the load
Problem: Low voltage alarm
Possible Causes
Solution
Battery no power Recharge the battery
Battery voltage too low or poor
