PWM controller with no float
OK, I have a Morningstar Sunsaver 20a PWM controller. It's not the current generation, which is a 3-stage unit. It's basically a 2-stage without the float stage. It delivers full amps till the targ...

It lets the voltage drop at night, so you don't get sustained 14+ volts.
Yes, 14+ it too high as a 24/7 float even with no amps, except when it is cold out
32F - 13.9v
15F - 14.2v
-5F - 14.4v
I think 14.4 all day during daylight would not be good in warmer temps in the long run. Agree with smk. Good for camping, not so good as a maintainer
I never did find out what my $13 RJ special does once the batts get charged up. Might be the same deal as that one. (Series type with constant voltage at the high set-point for Absorption while amps taper.)
