BF,
As you know, having as large a battery capacity as one either can fit or can afford means one may have battery capacity so large that - all or most of the time - one uses and recharges only the "very top" of their battery capacity. This means that one's battery(ies) will last the longest time possible, all other things being considered.
Staying as shallow as possible on daily battery discharge cycles is a good thing. One can achieve this simultaneous with heavy daily use of battery energy if their overall battery capacity is large. Also in emergency situations (such as extended low sun-light conditions or being otherwise "stranded"), one may thank their lucky stars that their battery capacity was "larger than normally necessary".
IMHO one need only match daily charging capacity (be it solar or generator) to whatever the average daily battery discharge levels are ... NOT match daily charging capacity to around 50% of whatever battery capacity is installed if installed capacity is large.
