What to do if the red LED is on on my Whistler XP200i Inverter?
- C
  Cheryl RiveraJul 28, 2025
  If the red LED is illuminated on your Whistler Inverter, it could be due to several reasons. First, the equipment connected might have a high start-up surge; try turning the inverter power switch to the center OFF position (O) and then back to Inv+USB (l) until your appliance starts. Repeat as needed. Second, the battery voltage might be below 10 volts; in this case, recharge or replace the battery. Finally, the inverter might be overheating (thermal shutdown mode); allow it to cool, ensure adequate ventilation, and reduce the load on the inverter output.

  The low battery alarm on your Whistler Inverter might be constantly on due to several reasons: * The input voltage may be below 11 volts; keep the input voltage above 11 volts to maintain regulation. * The battery condition might be poor or weak; consider replacing the battery. * Inadequate power is being delivered to the inverter, or there's excessive voltage drop; use a heavier gauge wire, especially for the 400-watt model.

  To stop TV interference caused by your Whistler Inverter, it may be due to electrical interference from the inverter itself. A suggested solution is to add a ferrite data line filter onto the TV power cord. These filters are available at electronic part stores.
