If I had kept the two 100s instead of selling them, I could have put them in series as a 200- 24 as an option. Now I have the (no option) 24v 230w instead.
My crystal ball wasn't working where I then got those free T-1275s that need separate solar from that on the four 6s, and I have been in a turmoil ever since. (BTW I am nursing them some more and they are showing signs of improvement, where before I reported that they were stuck as is. Another 'we'll see.")
I have now got it all more or less sorted out, except now I have too much battery and too much solar for any imaginable daily AH usage. Perhaps I should tell DW to haul out her crock pot! :)
