I also have a 2011 3100 and have upgraded my batteries and Xantrex converter. I called Xantrex and asked what the easiest conversion was and was told that their 2000 could also be programmed to properly charge LiPo4 batteries (to 14.6 volts, instead of the fully charged LA batteries at 12.8v) and was an easy change out. I believe this unit cost about $850, but, as they told me, it was a super easy exchange all of the wires that went into the 1800, went into the same holes on the new 2000. I also changed out my 2 golf cart batteries that weighed tons! and essentially ruined my battery pull-out tray, with 3-SOK 206 Ah LiPo4 batteries. I could only fit 1 SOK battery on the tray, but I built battery "holders" that bolt to the chassis frame. With the 800 watts of CIGS solar panels on the roof, we have camped under trees for 7 days, and every evening the 9000Wh of batteries were fully charged, even after using the griddle, coffee pot and hot pot in the morning, and running the refrigerator on 120V all day/night.
I know you asked about exchanging the Xantrex, but I also added 2 more inverters; a 2Kw Renogy for the microwave, and another 1Kw to charge everything else (E-Bike batteries etc) for a total of 5Kw of 120v power. I also have a Renogy DC to DC charger installed in case the solar panels need a bit of help. I don't like to over tax the stock alternator, so I went with the 20a model. I've read horror stories about burning up alternators with the higher current demand models and like to be safe. If you're further interested, let me know. Kirk Antes e-mail: thehomelessguy@yahoo.com
