If using a controller w/o float, if you drew AH from the fully charged battery and there was still sunlight, I would expect the charge to (resume in order to) keep up. Albeit at 14.4v, not 13.2.

IMO float is good in all conditions. Most alternators drop voltage with time based on heat or are controlled by the main ECM.

As a practical matter, is float mode necessary with solar charging? As an alternative, the controller would simply stop charging when the battery was full. The next day the process would repeat.
Floating was developed to maintain batteries over weeks and months of continuous charging. Solar charging is not continuous, and the cycle restarts each (sunny) day.
I wonder if solar float mode is "because we can and the customer thinks they need it", rather than because it produces any real benefit.
Couldn't the extra watts put in at float voltage be instead put in at absorption voltage? Amps would be low; charge pulses would be short. Is there float in an automotive alternator charge?

Porsche or Country Coach!
If there's a WILL, I want to be in it!
