The trouble is they call a cycle as being back to full. If you can get back to full you are not on generator. If you are getting back to full you aren't going down to 50%.
If on shore power you are not cycling the batts at all. So that leaves times on solar with only shallow cycles and getting back to full, or one cycle time off grid down to 50% and then on shore power for the run back up to full. But how many times in a row would you ever do that?
I can do about five 50-90s in a row before progressive capacity loss gets the batts down so that the next 50-90 will not put back in enough to get through to the next day. That works out to under two weeks off grid before needing shore power to do a full recovery.
Solar has changed that from under two weeks to five months plus. :) Untested for how long we could really go--years?
