Agreed, use long term off grid manufacturers gear, I can’t recommend reinventing the wheel.

I just got back from inspecting two Li+ off grid systems done by a GT dealer, and I saw numerous issues that included the charge controllers not agreeing with the BMS system, the BMS system monitoring having numerous programming and connectivity issues, the battery overall being vastly undersized, the manufacturer (Adara) dropping support for their battery, and the customers being hopping mad.  Most off grid folks own guns; not a good combination to walk into.

GT is usually never a life or death matter, but Off grid can be, when they are snowed in with no fridge, no water, no heat, and no communications.  Reliability is goal #1, Simplicity is #2.
