Xantrex Error Code 20

[Rivernerd]

When preparing our 2022 Elite II for a weekend outing, I found error code [20] displayed on the inverter remote panel.  When an inverter reboot produced no change, I consulted the section of the Oliver Owner's Manual Optional features book which addresses our Xantrex Freedom XC Pro 3000 watt inverter.  To my dismay, Error Code 20 does not appear in the table of error codes.  Codes 1-19, and then 21 are listed, along with their respective meanings, but not Code 20!

Since I was at home with good internet access, I checked the Oliver Knowledge Base.  Sure enough, Xantrex Error Code 20 is covered in detail there.  Included are instructions for resetting the inverter to clear Error Code 20.  I followed those instructions.  They worked.

I hope this post helps someone else who encounters Error Code 20.

Would you mind adding the direct link to this thread?  

I have tried tracing various Knowledge Base information from older posts, only to find the information missing, but it still might be helpful. I use the Knowledge Base a lot, as I continue to learn about the OTT. 

Also related to the Xantrex manual and codes: OTT Service department and I both tried to find the definition of "nAt" to no avail. I will make a separate post for that issue, but wanted to note it here.

Rivernerd,

I am also troubled with the Error Code 20.  I happens in our trailer every time our lithium batteries are significantly discharged (<80% SOC) and we then plug into shore power. I am always able to clear it until the next time we are discharged and then plug into shore power.  I have not done a software update yet.  Did you do the software update? Have you had the problem happen since the update? I have called xantrex several times and never got any useful suggestions. They always want me to check the communication wires between the inverter and the remote display. I have contacted Oliver and they referred me to the same link referenced above.

Thanks Robert and Cheryl

See if this helps.

Sorry for the late reply, but we were traveling in our Elite II this past weekend!

I did the firmware update.  I have had no [20] inverter error codes since then, but the battery State of Charge also has not dropped below 50% during that time either.  I recommend you do the firmware update.  Available here:

Thanks so much for the info. That helps me a lot. We are also traveling and I will update the firmware when we get home
