pure sine wave power inverter

1)Acoustics buzzer alarms. When applying the inverter to acoustics, some inferior acoustics will buzzer, that is because the output wave from of this inverter is modified sine wave. If it is pure sine wave, that is because of overload,. Please wait 20 seconds. After then if it still abnormal., turn off it to avoid wasting.

2)TV interference. You can get minimum interference trough filter. In some occasions, very faint interference will become obviously, you can try as follows. A: Let inverter far from TV and TV antenna. B: Try to change the direction of TV signal cable and TV antenna to reduce the interference to minimum. C: Select screen cable antenna with high quality.

3)Inverter no response. Poor connection between batteries & inverter, reconnect them.

4)Output voltage very low. 1. Overload. Load power exceeds rated power, shut off part of the appliances and restart inverter. 2. Input voltage too low. Make sure input voltage is within the rated range.

5)Low voltage alarm. 1. Battery no power. Recharge the battery. 2. Battery voltage too low or poor connection. Recharge the batteries, check terminal connection or clean terminals with a dry cloth.

6)Inverter no output. 1. Battery voltage too low, recharge or replace the batteries. power too high, shut off part of the appliances and restart inverter. 3.Inverter thermal protection. Cool the inverter and place it in the place with good ventilation. 4.inverter failure to start, restart the inverter 5. Reverse polarity connection and fuse melted, replace the fuse with a same spec fuse and reconnect.

7)Inverter does not work. Check the power switch, fuse and battery connecting cables or cigarette lighter.
