Solar Float and Shore Power Float?
Been a few threads on this, but I never had the "issue" until now, so I am not too clear on just what is at stake here.
On shore power Floating the batts at 13.8 (or whatever temp comp adjustment calls for) you get a steady "correct" voltage.
With solar only, no shore power, you Float the batts by letting the controller do its "profile" during the day and it quits at night. With any luck, you will average out a "correct" Float in the 24 hours for the batts to survive.
BUT as I have now discovered for myself (despite those other threads on this :( ), if you have both shore power and solar, then during the day, instead of being at 13.8 (say) steady, the solar puts you up into the 14s, and at night, instead of dropping right down, the shore power keeps the converter going at its 13.8 (say), so your 24 hour average is higher than it was when just on shore power.
So it looks like the answer, if you are on shore power and solar, is to disconnect the array from the controller (leaving the controller on the battery bank), and just stick with the shore power and converter's Float.
Yes?
