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...

Good for camping forever. Dubious as a maintainer for more than a few weeks IMO.
Sometimes Forum guys get to wondering whether solar storage maintainers that drop their voltages at night (as they must) are as good as shore power battery maintainers, which stay at 13.4v forever.
Mex says the constant float voltage is better than anything, but you do need shore power for that. So then you might ask, if solar is second best, how much farther off second best is that two stage thing?
I don't know.
