Applies to: Bluetti EP760.
| Code | What it means | What to do | Service | Manual |
|---|---|---|---|---|
| 10 Hardware LLC1 current overcurrent input | A hardware-level overcurrent on the LLC1 input. The manual lists it as a fault code without further explanation. | Please contact the BLUETTI support team. | dealer | p. 27 |
| 26 Hardware PV1 fault | A hardware-level fault on the PV1 input. The manual lists it as a fault code without further explanation. | Turn off the inverter and wait 30 minutes to restart it. If the symptom persists, please contact the BLUETTI support team. | dealer | p. 27 |
| 27 Hardware PV2 fault | A hardware-level fault on the PV2 input. The manual lists it as a fault code without further explanation. | Turn off the inverter and wait 30 minutes to restart it. If the symptom persists, please contact the BLUETTI support team. | dealer | p. 27 |
| 28 Hardware PV3 fault | A hardware-level fault on the PV3 input. The manual lists it as a fault code without further explanation. | Turn off the inverter and wait 30 minutes to restart it. If the symptom persists, please contact the BLUETTI support team. | dealer | p. 27 |
| 34 Hardware overcurrent input | A hardware-level overcurrent on the input. The manual lists it as a fault code without further explanation. | Turn off the inverter and wait 30 minutes to restart it. If the symptom persists, please contact the BLUETTI support team. | dealer | p. 27 |
| 5 Hardware BUS overvoltage | A hardware-level overvoltage on the inverter BUS. The manual lists it as a fault code without further explanation. | Please contact the BLUETTI support team. | dealer | p. 27 |
| 6 Hardware BUS2 overvoltage | A hardware-level overvoltage on the inverter BUS2. The manual lists it as a fault code without further explanation. | Please contact the BLUETTI support team. | dealer | p. 27 |
| 7 Hardware battery overvoltage | A hardware-level overvoltage on the battery side. The manual lists it as a fault code without further explanation. | Please contact the BLUETTI support team. | dealer | p. 27 |
| 8 Hardware inverter overcurrent | A hardware-level overcurrent in the inverter. The manual lists it as a fault code without further explanation. | Please contact the BLUETTI support team. | dealer | p. 27 |
| 16 PV1 Voltage High | The voltage of the PV1 input is above the allowed limit. The solar array's total voltage is too high for the inverter. | Check if the total voltage of solar panels exceeds the limit. Reduce the number of solar panels, and the inverter resumes operation after calibration. | owner | p. 72 |
| 17 PV2 Voltage High | The voltage of the PV2 input is above the allowed limit. The solar array's total voltage is too high for the inverter. | Check if the total voltage of solar panels exceeds the limit. Reduce the number of solar panels, and the inverter resumes operation after calibration. | owner | p. 72 |
| 18 PV3 Voltage High | The voltage of the PV3 input is above the allowed limit. The solar array's total voltage is too high for the inverter. | Check if the total voltage of solar panels exceeds the limit. Reduce the number of solar panels, and the inverter resumes operation after calibration. | owner | p. 72 |
| 19 PV1 ISO Failure | An insulation fault on the PV1 array. The manual associates it with a possible short between the solar array and ground. | Check the insulation resistor between solar array and grounding for a short circuit. | owner | p. 72 |
| 20 PV2 ISO Failure | An insulation fault on the PV2 array. The manual associates it with a possible short between the solar array and ground. | Check the insulation resistor between solar array and grounding for a short circuit. | owner | p. 72 |
| 21 PV3 ISO Failure | An insulation fault on the PV3 array. The manual associates it with a possible short between the solar array and ground. | Check the insulation resistor between solar array and grounding for a short circuit. | owner | p. 72 |
| 32 Fan Failure | The inverter cooling fan is not working correctly. | Check if the inverter fan operates well. | owner | p. 73 |
| 35 DC Input Voltage Low | The DC input voltage is too low for normal operation. | Check if the DC voltage is too low. | owner | p. 73 |
| 36 DC Input Voltage High | The DC input voltage does not match the battery specifications. | Check if the DC voltage is inconsistent with the battery specifications. | owner | p. 73 |
