Error codes and troubleshooting
| Code | Meaning | What to do | Manual page |
|---|---|---|---|
| Temperature Alarm | The temperature alarm icon appears when the power station or its battery gets too hot. | Remove the load and let the station cool down, or move it to a cooler environment if possible. Press the appropriate power button to reset the circuit. Let the fans run a few minutes, then reduce the load and try again. | 8 |
| High Temperature | The battery has become too warm and the overheating alarm icon appears on the panel. | Remove the load and let the unit cool down, or use it in a cooler environment if possible. Press the appropriate power button to reset the circuit. Let the fans run a few minutes, then reduce the load and try again. | 11 |
| Overload | Too much power is being drawn from the power station. It cuts off power to protect itself and the battery, and the overload alarm icon appears on the display. | Disconnect the load and press the appropriate power button on the panel to reset the circuit. | 11 |
| F001 | Main inverter communication is abnormal. | Contact WEN customer service for assistance. Call service if it persists. | 13 |
| F004 | The main inverter is overheated. | Make sure the fan is working. Turn unit off and move it to a cooler environment. Let it cool down for at least 1 hour if possible, then restart it. | 13 |

FAQ
How long will the WEN PP300i run a refrigerator?
About 5 hours for a typical 120 W refrigerator that runs 35 % of the time, after inverter and depth-of-discharge losses.
Can the WEN PP300i start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 600 W peak. That is below a typical 1/2 HP sump pump start (about 2150 W); check your pump label. Use the calculator with your exact pump.
