| Code | What it means | What to do | Service | Manual |
|---|---|---|---|---|
| E004 Output failure | The output voltage is outside the expected range, or the grid connection is not proper. | Ensure the output voltage is within ±10% of the rated voltage or proper grid connection. | owner | p. 21 |
| E016 Fan failure | The internal fan is blocked, unplugged, or not functioning properly. | Check if the fan is blocked, unplugged, or not functioning properly. Ensure proper ventilation. | owner | p. 21 |
| E117 Grid oscillation | Grid oscillation has been detected at the grid input. | Disconnect the grid input and contact BLUETTI support for further assistance. | dealer | p. 21 |
| Others | Other errors not listed in the error code table. | Contact BLUETTI support for help. | dealer | p. 22 |
| E001 Inverter overload | The inverter is overloaded because the connected devices draw too much power. | Check whether the power consumption of your devices is too high. Reduce the load if necessary. | owner | p. 23 |
| E002 Inverter overtemperature protection, AC output off | The inverter overheated and protection switched the AC output off. | Wait for about 10 minutes until the unit cools down, then turn on the AC output again. | owner | p. 23 |
| E003 Inverter short circuit | A short circuit has been detected at the inverter output. | 1. Check whether the power consumption of your devices is too high. 2. Check whether any of your electrical devices are causing a short circuit. | owner | p. 23 |
| E026 Unit overload | Total unit output is overloaded. | Check if the AC and DC output is above 2,800W. | owner | p. 23 |
| E033 PV overvoltage | The solar (PV) input voltage is above the accepted range. | Make sure the PV input voltage is within the range of 12V to 28VDC. | owner | p. 23 |
| E039 PV overtemperature | The PV input has overheated. | Wait for about 10 minutes until the unit cools down, then re-enable the PV input. | owner | p. 23 |
| E065 DC output short circuit | A short circuit has been detected at the DC output. | 1. Check whether the power consumption of your devices is too high. 2. Check whether any of your electrical devices are causing a short circuit. | owner | p. 23 |
| E067 DC output overcurrent | The DC output is drawing more current than allowed. | Check whether the power consumption of your devices is too high. Reduce the load if necessary. | owner | p. 23 |
| E068 DC output overtemperature | The DC output has overheated. | Wait for about 10 minutes until the unit cools down, then restart your devices. | owner | p. 23 |
| E085 Charging temperature too high | The unit's temperature is too high for charging. | Wait for the unit to cool down before charging. | owner | p. 23 |
| E086 Charging temperature too low | The unit's temperature is too low for charging. | Make sure the unit is placed in an ambient temperature of 0°C to 40°C (32°F to 104°F). | owner | p. 23 |
| E087 Discharging temperature too high | The unit's temperature is too high for discharging. | Wait for the unit to cool down before discharging. | owner | p. 23 |
| / Others | An unspecified fault not covered by the listed error codes. | Please contact BLUETTI support for assistance. | dealer | p. 24 |
| E088 Discharging temperature too low | The unit's temperature is too low for discharging. | Make sure the unit is placed in an ambient temperature of -20°C to 40°C (-4°F to 104°F). | owner | p. 24 |
| E113 Grid overvoltage | The grid input voltage is too high. | Check if the grid voltage is too high. Change the input source if necessary. | owner | p. 24 |
| E114 Grid undervoltage | The grid input voltage is too low. | Check if the grid voltage is too low. Change the input source if necessary. | owner | p. 24 |
| E115 Grid overfrequency | The grid frequency is too high. | Check if the grid frequency is too high. Contact your local power provider if necessary. | owner | p. 24 |
| E116 Grid underfrequency | The grid frequency is too low. | Check if the grid frequency is too low. Contact your local power provider if necessary. | owner | p. 24 |
