I have a portable 160w solar panel system with 2@ 80w panels wired in parallel for 12v charging. I have a PWM type controller mounted on the back of the panels that I use to charge a battery bank in my RV.
I would like to use these same panels to charge a 48v battery bank in a golf cart. Is there a controller that can accept a 12v or 24v input and "step-up" the voltage output to charge a 48 volt system? I have found DC-DC step up converters, but I would like a PWM or similar multi-phase charge regime and not just a voltage converter. I assume that I cannot just take the output from my 12v controller and step it up to 48v as the controller will no longer sense the battery condition and phase the charge.
I found the controller SORCV12/36-4PV on this site, but it only has a 36 volt output. Is this the type of device I need? Can it be found in 48v output? Does anybody make a dual voltage controller so that I can use the portable system to charge both the 12v RV and the 48v golf cart (not at the same time ...)?
Any suggestions would be appreciated.
