Troubleshooting Xantrex Pro XM 1800 Inverter E05 Error Code
Updated 02/10/2026 | Published 01/22/2026
Question:
I have an Xantrex Pro XM 1800 inverter it keeps sending a EO5 OL code. I have cleared it a few times but it keeps coming back. Also it is drying the house batteries. Is there a way to test or do I need to replace.

Hey Karl, while we don't carry the Xantrex Pro XM 1800 inverter I was able to find that the E05 error code indicates that there is an overload condition triggered by drawing too much power or poor ventilation, but can sometimes point to a short or low battery voltage.
Have you checked your setup for any of those issues? If nothing is wrong and your still getting that error I would assume the inverter is bad and needs to be replaced. We have a similar 1800 watt inverter with the part # GP94XR. This a really reliable inverter that will last longer than the Xantrex.
