What converter is in my new 2022 XLS 22RBE?
I just bought a 2022 XLS 22RBE and I am already looking at the solar setup. I haven't even picked it up yet and I am planning upgrades. Do the converter/chargers support LifePO4 charging or should I plan on replacing it. I have a 300ah LifePO4 Chins from my old rig and plan on using it and want to charge it fully when on shore/genny power.

According to GD parts look up it is a WFCO converter

I don't think any of the WFCO that GD uses are lifepo4 ready. They will charge them but not fully. The converter/charger in the XLS lines are 1 piece and has to be completely changed. Not a huge job but not a quick one either. PD4135 is the replacement from Progressive Dynamics which is lithium ready.

First off, welcome to the forum, hope you enjoy the new coach. As stated by others, your charger/converter is most likely not Lifepo4 aware, it will charge but not all the way. The solar charge controller you got, by contrast, probably is Lifepo4 aware and will charge your battery the rest of the way if you have enough sun.

One thing I don't see mentioned above: the Serial Number Data Sheet that came in the paperwork packet with your RV from GD will tell you the make and model number of the converter/charger installed in your unit. You can use that information to look it up on the manufacturer's web site (WFCO, etc.) and see all of its specifications. There's also likely a manual for it in that same paperwork packet.

Thank you everyone for the input. My new 2022 XLS 17MKE has a WFCO WF-8735-AD-GE and it WILL charge Li batteries to 100%. The AD in the part number means Auto Detect and on LI mode the charge voltage goes up 14.6 volts @ 32.5 amps.
