Background
An old gentleman and a newbie. I am retired and no place to live so I bought a 1998 coach to live in. I installed solar but I don’t understand amps. I have 3 float acid batteries that says 20 amp hrs on them. I don’t know what that means or how long they would last. I think I need lithium but they are to expensive. I have a freedom 20 inverter/ charger. Can you help me out
