What to do if the OVERTEMP red LED is on and a buzzer is heard on my Trace Engineering DR Inverter?
- C
  Courtney JenkinsAug 19, 2025
  If the OVERTEMP red LED is on and you hear a buzzer on your Trace Engineering Inverter, it could be due to several reasons: * High AC input voltage. * Operating too large of a load for too long. * High ambient temperature. * Failed inverter cooling fans or blocked airflow. To resolve this, check for high input AC voltage, reduce the load, allow the inverter to cool before restarting, and inspect the cooling fans and airflow.

Why is the BATTERY LOW green LED on and a buzzer heard on my Trace Engineering DR Inverter?
- P
  Patrick BrownAug 22, 2025
  If the BATTERY LOW green LED is on and a buzzer sounds on your Trace Engineering Inverter, the battery voltage is below the low battery voltage input tolerance, triggering the OVER-DISCHARGE PROTECTION circuit. Here's what you can do: 1. Charge the battery. 2. Disable the OVER-DISCHARGE PROTECTION setting by turning the adjustment to OFF. 3. Check the battery voltage at the inverter's DC input terminals. 4. Check for any external DC load on the batteries. 5. Assess the condition of the batteries and recharge them if possible. 6. Inspect the 'AC INPUT' circuit breaker on the side of the inverter.

What to do if the OVERLOAD green LED is on for my Trace Engineering Inverter?
- T
  Tiffany JacksonAug 25, 2025
  If the OVERLOAD green LED is on for your Trace Engineering Inverter, it could mean several things: * There's an excessive load on the AC output. * An AC source was directly wired to the AC output. * The AC output of the inverter is wired back to its own AC input. * The charger circuit might be damaged. To address this, remove excessive AC loads and restart the inverter. Ensure proper AC input and output wiring. If the issue persists, the inverter/charger may need servicing.

Why is the BATTERY HI red LED on and a buzzer heard on my Trace Engineering DR?
- J
  John MitchellAug 26, 2025
  If the BATTERY HI red LED is on and a buzzer is heard on your Trace Engineering Inverter, it means the battery voltage is above the high battery voltage input tolerance. Check the battery voltage at the inverter’s DC input terminals and ensure your DC source is regulated below your high battery cut-out voltage.

What to do if the CHARGER LED is on but my Trace Engineering DR batteries are not charging?
- M
  Mrs. Whitney WashingtonAug 28, 2025
  If the CHARGER LED indicates charging but the batteries aren't charging, or if the LED is on but there's no output power from your Trace Engineering Inverter, it could be due to: * An open circuit breaker on the side of the inverter. * No AC voltage at the inverter's AC terminal block. * Good AC voltage at the inverter's AC terminal block. To resolve this, engage the 'AC INPUT' circuit breaker on the side of the unit. Check the 'AC PASS-THRU' circuit breaker on the side of the inverter. Also, check for open AC output breakers or fuses and AC wiring connections.

Why is my Trace Engineering DR in INVERTER MODE with no power output?
- S
  Sandra DeleonAug 30, 2025
  If your Trace Engineering Inverter is in INVERTER MODE but there's no power output, and the LED is either on or flashing, it could be due to: * Good AC voltage on the inverter AC terminal block (but open AC output). * No AC voltage on the inverter AC terminal block. * A load that's too small for the search mode circuit to detect. To troubleshoot, check for open AC output breakers or fuses and AC wiring connections. If there is no AC voltage on the terminal block, have the unit serviced. If the load is too small, reduce the search mode watts setting, increase your AC load, or disable the search mode setting.

Why is my Trace Engineering DR charger inoperative or giving a low charge rate?
- J
  Joshua ChapmanSep 1, 2025
  If your Trace Engineering Inverter charger is inoperative or giving a low charge rate, it could be due to several factors: * AC voltage has dropped out-of-tolerance. * Charger controls are improperly set. * Low peak AC input voltage. * AC current output of the generator is too small. * Loose or corroded battery cable connections. * Loose AC output connections. * Generator instability causing loss of synchronization. To address this, check your AC voltage and frequency, refer to the owner’s manual for proper charge rate settings, use a larger generator, reduce charge amps setting or pass-through loads, check and clean all cable connections, check all AC output wiring connections, or turn the battery charger rate knob down.

Why does my Trace Engineering Inverter have low surge power?
- M
  melindabakerSep 3, 2025
  If your Trace Engineering Inverter has low surge power, it could be due to weak batteries or battery cables that are too small or too long. Refer to the cable and battery recommendations in the owner’s manual.

Why do AC lights flicker while charging with my Trace Engineering Inverter?
- J
  Janet WrightSep 6, 2025
  If the AC lights flicker while your Trace Engineering Inverter is charging, it's likely due to generator instability, causing the charger to lose synchronization. To resolve this, turn the battery charger rate knob down to less than half-way until the problem is gone.

What to do if my Trace Engineering Inverter has low power output and turns loads on and off?
- T
  Terrance BakerSep 8, 2025
  If your Trace Engineering Inverter has low power output and turns loads on and off, it's likely due to a low battery. Check the condition of the batteries and recharge if possible.
