Solar alone or the alternator won't do it?
Above was for normal lead banks, FLA or AGM.
Only situations where alt or gennie is running all day or night anyway will get to 100%, the last 5 hours is tiny current, not worth burning fuel.
Solar alone is fine to get to 100%, as long as over-sized proportional to bank, unless you live where clear skies are the norm year round, have to size for worst-case weather + heavy usage.
Usually better to have a small gennie + big charger to help with the worst case times.
Especially where space for panels is limited.
