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...

You have a simple, single stage controller. You have a choice with a single stage
a) Charge the batteries at a ridiculously slow rate and avoid overcharge
b) Charge the batteries at a decently fast rate but then overcharge them
(boil).
THE CHEAP WAY OUT?
Buy a twelve hour wind up timer then give it your best shot at 14.4 volts. Heavy use? Then it'll be dawn till dusk. A voltmeter should be used. The days of non-use will be days of no charging unless you set the charger to float (see below) and bypass the timer.
Reset the charge rate to 13.3 for storage and let'r rip without the timer.
You COULD get overly clever and wire the timer so when you wind it up it BYPASSES a SILICON DIODE circuit feeding the battery. When the timer runs out, 14.4 volts minus .7 volts for the silicon diode voltage drop = 13.7 volts.
Hope This Helps
