Xantrex RV inverter / charger fault codes
RV inverters and inverter/chargers convert battery power to 120/230V AC. Faults (overload, low/high battery, overtemperature) show as codes or LED/beep patterns.
How to read the code
Note the error code or the LED colour + beep count, and check battery voltage and load first — overload and low battery are the most common trips.
All documented codes
E01 warning
The battery voltage has fallen low enough that the inverter is about to shut down to avoid… E02 warning
High battery voltage shutdown. The DC input voltage has risen above about 18.0 volts, so t… E03 warning
AC output overload shutdown. The connected AC load exceeded the inverter's rated output (a… E04 warning
Over-temperature shutdown. The inverter's internal temperature reached its protective limi… E10–E19 danger
Internal hardware error. The inverter/charger detected an internal fault in either battery…
