Almot I'm intrigued by your idea to pair a Meanwell PS to a charge controller. If this is possible why would the Meanwell be needed? Couldn't the CC just be hooked to the 13.6v (or 13.2v float) output of a regular converter. Anyway, doesn't apply to me since I don't have shore power at my storage place. If I get a Meanwell it will be for battery maintenance in the driveway before storage.
Let me elaborate on a few things about the Blue Sky SC30 Controller. I have attached the manual. Also in my previous post I did mean schedule an equalization as often as five days.
The SC30 has a charge status indicator that clearly shows whether it's in bulk, abs, float or eq. The manual seems to indicate that it will go into absorption every morning (assuming sun is out) and hold abs for the set time. I called Blue Sky and they confirmed that it will run a daily abs cycle whether needed or not. We agreed that I should set the abs time to probably 1/2 hour when in storage.
Now I won't know for sure if it runs a daily abs cycle until I test it. With a fully charged battery I will cover the solar panel overnight. I'll go to the trailer the next morning and remove the cover. It will either run the abs cycle or quickly go to float.
Now my limited understanding of these adjustable charge controllers having a set abs time is so you can adjust to figure out what keeps your specific batteries fully charged. No CC can figure it out based upon tapering current.
Now the Bogart CC paired with the Trimetric is supposed to be super smart to prevent potential overcharging buy measuring amps in and amps out so it doesn't run a daily abs cycle if not needed.
My Go Power CC that I just replaced worked the same as the Blue Sky but it wasn't adjustable. It would run what it called a boost cycle for 1/2 hour every morning at 14.4v whether the battery needed it or not.
Interstate does have an abs time spec for their GC2 batteries. It is between 2-4 hours. Their eq spec time is also two hours.
So my plan is to set the SC30 to interstate abs specs (15.3v for two hours) when I am using the trailer and lower abs voltage and time when it is in storage (currently set to 15v for 1 hour).
Am I missing something about how these charge controllers work? You either choose one that determines when the battery is charged in which case it will always undercharge the batteries or you get a fully adjustable one and figure out the best settings to allow full charge and minimize fluid loss, right?
Or you get the Bogart with Trimetric which should stay in float until the Trimetric senses amps out.
So what is better for GC2 batteries during storage. Constant float or a daily abs to stir the electrolyte?
