Default August 10 - Hot Time In The Old Town, Tonight - Again (last one was several weeks ago)

Skip,

Even starting with that thoroughly depleted bank, you should have full
charge by now and equalization should have taken place.

Everything I hear indicates lots of lose or dirty connections or
undersized wiring (which I don't expect with the newly installed
stuff), lots of voltage drop in the lines. It's so endemic that I
suspect the main cables. Even with our trivial loads and small engine,
we got much better transfer when we went from basically heavy-duty auto
cables to 2/0 and 1/0 and cut the line length down from about 40' total
to about 12.

Sounds like that will the problem that's going to take you the longest
to solve on this shake-down.
