Xantrex Inverter/Charger questions

[Gliddenwoods]

A few (basic?) Xantrex Inverter/charger questions. I had some recent battery charging issues which are hopefully resolved and I want to check related items to make sure settings and software status were not changed by mistake during the process.

1. Where do I find the recommended settings to confirm/adjust my current settings on the Xantrex Inverter/Charger? I have the 3000 model.

2. Any advice/warning on the potential setting adjustments related to #1 above?

3. Where do I find the recommended/current Firmware versions? (Mine currently displays U1 03 19, U2 01 28 & U3 01 07).

4. Where do I find instructions on how to download/update the firmwares if required?

Thanks.

this table shows settings for various lithium batteries.  The red is for 2 large Lithionics using the 2000 watt inverter.

Hope this helps.

One tweak to the above settings if you experience low battery shutdown when using the 3000-watt inverter to power high-wattage appliances (like the microwave) with some later 2022 Elite II hulls: reset setting No. 02 for LBCO (Low Battery Cut Off) voltage to 11.5V rather than 12.1.  Our Hull #1291 has the "new" 12V bus bar, which Jason Essary advised requires that LBCO be set to 11.5V.

See my post on refining the settings on the Xantrex. Not sure how to link, here is the reference.

The only settings that I change on the Xantrex phone app are the "breaker rating" and "charger current". If I'm at a site with a good 30a outlet, I'll turn the breaker rating all the way up to 25a or 30a, but if I'm using a little 120v outlet (like at a friend's house) I dial that back to 10a or even 5a to make sure I don't trip their breaker. The charger current gets dialed back accordingly. A third thing I've changed is the "custom absorption voltage". I was having a hard time getting the batteries all the way up to 100% SOC. They seemed to stop at 97% or 98%. I contacted Lithionics and they told me to change the custom absorption voltage to 14.6v, which I did, and haven't had that problem since.

I recently updated my firmware on my xantrex 3000 because I was have issues with frequent error 20 messages.  One thing I found interesting is that the xantrex instructions do not recommend updating firmware unless you are having issues. I used instructions from both the Oliver knowledge base and the xantrex page to download all three firmwares and update.

Maybe a case of "If it ain't broke, don't fix it!" Just in case it would brick the inverter. Oh! I should install the firmware upgrades over and over until I *do* brick it. Then I'll have an excuse to swap in the Victron unit. 😉

If you haven’t already done so, I recommend downloading the FXC Xantrex Control app. It makes it much easier than using the remote display to check or change the settings.
