Error codes and troubleshooting
| Code | Meaning | What to do | Manual page |
|---|---|---|---|
| AC overload protection | No AC output because the AC overload protection has tripped, usually caused by a load-related problem. | Remove the problem load, shut down the generator, and restart it. | 24 |
| CO exceeding specified standard values | Carbon monoxide levels exceed the specified standard, most likely due to poor ventilation. | Turn off the generator and improve ventilation. | 24 |
| Communication failure | Communication with DELTA Max or DELTA Pro has failed. It is normal when the generator enters sleep mode. It is abnormal if it persists after activation or while running. | If the generator is asleep, press a button to wake it. If the failure persists, stop using the product and contact the service personnel or the service dealer. Call service if it persists. | 24 |
| DC overload protection | No DC output because the DC overload protection has tripped, usually caused by a load-related problem. | Remove the problem load, shut down the generator, and restart it. | 24 |
| Oil Alert Indicator | Engine oil level is low. The engine oil alarm system may shut off the engine. | Add engine oil. | 24 |
| Over-temperature protection | No output because the generator is overheating. Possible causes are a blocked air inlet, high ambient temperature, or too large a load. | Check the air inlet, move the generator out of the high-temperature environment, or reduce the load. | 24 |

FAQ
Can the EcoFlow Smart Generator (Dual Fuel) start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 4000 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
