Common Problems

Buzz in Audio Equipment

Some inexpensive stereo systems emit a buzzing noise from their loudspeakers when operated from the PROwatt 1000. This occurs because the power supply in the audio system does not adequately filter the modified sine wave produced by the inverter. The only solution is to use a sound system that has a higher quality power supply.

Television Reception

When it is operating, the PROwatt 1000 can interfere with television reception on some channels. If interference occurs, try the following:

1.Make sure the chassis ground screw on the rear of the Prowatt 1000 is solidly connected to the ground system of your vehicle, boat, or home.

2.Make sure the television antenna provides an adequate (“snow-free”) signal and that you are using good quality cable between the antenna and the television.

3.Keep the cables between the battery and the Prowatt 1000 as short as possible and twist them together with two to three twists per foot. (This minimizes radiated interference from the cables.)

4.Move the television as far away from the Prowatt 1000 as possible.

5.Do not operate high power loads with the Prowatt 1000 while the television is on.
