What to do if my Black & Decker MAXX SST Inverter has no AC output and the red LED is lit?
- B
  Brandon ChungJul 30, 2025
  If the red LED is lit and there's no AC output from your Black & Decker Inverter, it could be due to the DC input being below 10 volts. Try recharging or replacing the battery. Alternatively, an excessive appliance load might have caused a thermal shutdown. In that case, turn the unit off, reduce the load, wait for the inverter to cool down, and then turn it on again.

Why does the low battery alarm sound continuously on my Black & Decker MAXX SST Inverter?
- A
  Antonio SmithAug 2, 2025
  If your Black & Decker Inverter's low battery alarm sounds continuously, it could be due to low battery voltage. Try recharging the battery and remove the load from the inverter while it's recharging. Another possible cause is a bad connection or wiring. In this case, tighten all DC connections.

  vanessa88Aug 11, 2025
  If your Black & Decker Inverter is causing television interference, position the inverter as far as possible from the television, the antenna, and the antenna cables. Use an extension cable if needed. Also, adjust the orientation of the inverter, the antenna cables, and the TV power cord to minimize interference. Ensure the antenna provides an adequate signal and use high-quality, shielded antenna cable. Avoid operating high-power appliances or tools simultaneously with the TV. Finally, make sure the inverter’s case is properly grounded.

  If the green LED is not lit and there's no AC output from your Black & Decker Inverter, the fuse(s) might be open. Check the DC input fuse(s) in the vehicle and replace the fuse with one of the same type and rating if necessary.

Why is my motorized power tool not operating at correct speed with Black & Decker MAXX SST?
- R
  reesedanielleAug 20, 2025
  If your motorized power tool does not operate at the correct speed when using the Black & Decker Inverter, it may be due to a purely inductive load. To resolve this, make the load not purely inductive by operating an incandescent lamp at the same time as the motor.

Why is my Black & Decker MAXX SST Inverter causing a buzzing sound in my audio system?
- D
  Denise OwensAug 25, 2025
  If you hear a buzzing sound in your audio systems when using the Black & Decker Inverter, it's because the power supply in the electronic device does not adequately filter the modified sine wave produced by the inverter. To fix this, use a higher quality sound system that incorporates a higher quality power amplified supply.
