| E3 | Low Voltage <104V | Try different site |
| E4 | Overload >30A | Reduce load |
| E5 | Over-Temperature 200°F | Allow unit to cool |
| E6 | Open Ground | Report to campground |
| E7 | Low Frequency <52Hz | Generator overloaded |
| E8 | High Frequency >69Hz | Non-standard source |
| Err0 | Internal Fault | Contact support |
