I'm not sure how to descrbe this problem but here's my best shot...
I've had a 48v solar setup for a year and a half running the ac side of my 5th wheel with good success. My only problem is I don't understand how to tie it in to the RV's 12v system. I need to replace the factory12v battery and would prefer to tie it in to my existing 48v lithium battery bank, but I don't know how to go about doing it. I've looked at this stepdown converter on Amazon (https://amzn.to/3UTVOT7 - not an affiliate link) but I don't know enough about how it all works to be sure it is the way to go. What is the right/best way to do this?
