This is more than you may want, but my lithium & solar system has been working perfectly for me for the last 2+ years in my 2018 Axis 24.1. It can be seen at

Since we always boondock at 30 ski resorts in the winter (w/ Ikon ski passes) & dirtbike in the summer, we never hook up to shore power. We don’t have to start the generator to make coffee & microwave breakfast in the morning. We never run out of power for our heated blankets overnight. We can even run the AC without the genny for about an hour with the soft start upgrade. Lithiums do not like freezing weather, so this is all under the bed and behind insulation from the back & sides. I removed the converter because the lithiums stay charged with the solar panels most of the time. Otherwise, the generator can charge the lithiums very quickly. I like that I can check the solar & battery stats & history with the Victron iphone app. Lithiums are relatively light batteries & can go down to almost zero percent charge without damaging them.
