Had my new apex running for a week now. It switched to backup mode for bad weather charged battery fully now getting E074 error then when I get the other codes its P024 Cell over voltage protection. Any suggestions?
Hi @Rickyk,
This is what I was able to find regarding the error codes:
| Error Code | Description | Solution |
|---|---|---|
| E074 | BMS System Fault (Please check the specific fault in the mobile app) |
- Charging temperature too high: Wait for the device to cool down before charging. - Charging temperature too low: Place the device in an environment with a temperature range of -15°C to 40°C (5°F to 104°F) before charging. - Discharging temperature too high: Wait for the device to cool down before using. - Discharging temperature too low: Place the device in an environment with a temperature range of -25°C to 40°C (-13°F to 104°F) before using. |
| P024 | Single Cell Overvoltage Protection | Restart the system. If the issue persists, please contact BLUETTI support. |
Thanks it was charging from 50% or so all the way to 100% but only at 8 amps. It turned off AC out, kinda cleared itself turned ac out back on no issues. Will try and duplicate.
