I, too, am interested in how this issue gets resolved.
I also want to highlight some of the benefits/versatility (at least for me) using a solar/electric UTV (Hisun Sector E1):
I traveled deep into public lands in New Mexico with a high-efficiency electric refrigerator (store food/game) and electric skillet (no open flames for cooking).
The Hisun also powers a cabin entirely or as an augmented source when needed.
I plan to replace all the lead-acid batteries with LiFePo4 batteries. I have already done so for the cabin with very good results.
