Gnubie how can you be a moderator in a newbie section of a forum where members go admitting limited understanding of solar systems? You write a cryptic post (for a newbie audience) then insult a member who asked for clarification by implying that they may be purposely feigning misunderstanding! It’s hard to know how to say how inappropriate your reply was. A bit more appropriate reply would state something like: Bottom line it’s dangerous to not have a proper earth ground, you won’t get an effective ground protection from your hardware alone so you need to handle that. I’m no expert but I am guessing the answer would be drive to an 8 foot earth ground into the soil, connect it with solid copper ground wire to you system as show in this picture or diagram (that you declined to provide). If it is an RV installation do this..... (I have no clue on that one).
