What is the exact or wattage capacity of your JTE inverter?

Use the heavy-gauge cables included in your JTE packaging. Undersized wires cause voltage drops and generate dangerous heat. Step 3: Connect to the Battery

Lower carrier frequency (2 kHz) reduces electrical noise but increases motor audible whine. Higher carrier (8 kHz) is silent but increases inverter heat. Default is 4 kHz.

| Fault Code | Typical Description | Common Causes | Recommended Actions | | :--- | :--- | :--- | :--- | | | Overcurrent during Acceleration | Load too heavy; Acceleration time too short; Motor short circuit | Increase acceleration time (P0.17); Inspect load and motor wiring | | E-11 / UV | DC Bus Undervoltage | Input supply voltage too low or unstable; Power component failure | Check input voltage level (should be >305V); Verify fuses/circuit breakers | | E-12 / OV | DC Bus Overvoltage | Deceleration time too short, causing regenerative energy; Braking resistor issue | Increase deceleration time; Enable overvoltage stall prevention (P5.02); Install a braking resistor | | E-15 / OH1 | IGBT Overheat | Ambient temperature too high; Cooling fan failure; Overload | Clean heat sink and vents; Check if the cooling fan is running; Reduce load | | OL2 / OL3 | Inverter Overload | Output current has exceeded the inverter rating; Heavy load | Check if motor load is stuck or jammed; Increase inverter capacity |

Charge the batteries; upgrade to thicker gauge copper cables. Alternator or solar charger voltage is too high. Check your charge controller settings; lower input voltage. Overload Protection (OL) Connected appliances exceed inverter capacity.

Every JTE manual contains a "Fault Code" table. Here are the most common errors:

Disconnect high-surge items (refrigerators, pumps, microwaves). Internal heat exceeds 65°C due to blocked vents. Turn off the unit; let it cool; clear dust from the fans. Short Circuit Protection Faulty appliance appliance or shorted AC wiring.

Cause: Deceleration time is too fast, causing the motor to act as a generator and dump energy back into the drive; fluctuating supply voltage.

To help provide the most relevant answers or look up specific configuration codes, please let me know:

The internal cooling fan is blocked or disconnected.

The most common source of failure is poor installation. The manual provides:

Secure the black negative (-) cable to the black terminal on the back of the inverter. Note: A small spark during connection is normal as internal capacitors charge. Step 5: Grounding

What is the or wattage rating of your JTE inverter? What voltage is your battery system (12V, 24V, or 48V)?

Connect the black cable to the negative (-) terminal of the battery. Step 4: Connect to the Inverter

Cause: The heat sink temperature is too high due to inadequate ventilation or a failed internal cooling fan.
