Consider that you may not need one at all, just a 120V charger instead. Depending on your loads and your battery capacity, your house circuits can simply run off the battery with your solar array charging them each day. That's now mine works. In the upgrade process I did source a 'lithium compatible' converter-charger, but ended up using it as a fixed voltage power supply that I can turn on when needed with shorepower or generator. So far we haven't used it.
I also added a DC-to-DC charger from the engine starting batteries (motorhome) for when we're driving. It's an 18A Victron Orion and works really well.
I had a whole thread on the new Powermax lithium series converters, and after a lot of discussion and testing we all decided a charger where needed would work just as well or better.
My recommendation is for either a Meanwell NPB series as Jim mentioned, or a Victron IP22 series. Both can be configured for LFP, and both can be set to terminate charging based on settings/parameters. Victron has a very slick BT app interface for settings and control.
The problem with most converter/chargers is they either don't put enough current through, or too much, or at too high or low of a fixed voltage, or they don't terminate charging, but float too high.
Old converter discussion thread here:
Newly released 2-stage converter/charger specifically for LiFePo4 batteries. Optional 3-stage for others if you need/want that option. On doing a ton of research on updating my RV charging systems for a new lifepo pack I found these. Just got off the phone with them there today, they just got...
