I have a RV with a 24v Multiplus 3000. This is used in combination with my MPPT charger to charge my 24v house batteries.
I have a generator that uses a 12v starter battery that I would like to trickle charge using the built in Trickle charge connection on the Multiplus:
The install/user guides do not provide any information other than the Trickle charger provides 4A of current. I've measured the voltage coming out of it when I attached my Starter battery and observed current ranging from 13.5v 4A to 16v .5A.
Q1: What is the nominal voltage provided by this connection? 12v 24v?
Q2: Is there any "smart charging" provided by this trickle connection? Or is it supposed to provide a "dumb" flat charge/voltage?
Q3: If this is a 24v connection, what would you suggest for charging my 12v starter battery (there is NO alternator in my system)?
Please share your solutions! I'd love to hear what you figured out.
Cheers!
