I have been looking at the Sterling website, as I ponder an upgrade to my charging system. I noticed that the product line has been greatly expanded over the past few years.
One thing that I just can't get my head around is the practical
difference between their "Advanced Alternator Regulators," for example the ProReg-B (approx $130), and their "ProAlt-C" Alternator to Battery Charger, for example the 12 Volt to 130 AMP Charger (approx $400). These both have 4 stage charging profiles for several different battery types. I understand that the regulator does not factor in multiple battery banks, but you can do this quickly, and easily, with an echo-charger.
My question is this; If using an "Advanced Alternator Regulator: with an "Echo Charge," to provide charging to multiple banks, haven't you accomplished the same thing as the Alternator to Battery Charger?
To put this in context - on my boat I currently have two 105AH (20 hour rate) batteries, as separate banks, connected via a Xantrex Echo Charge. Motor charging is from a Leece-Neville 90 Amp alternator, with the included 8RG2043 C (14.4V) regulator. Dock charging is from an IOTA DLS30/IQ4. I am considering combining the two 105AH batteries into one house bank, and adding a third (smaller) start battery.
Thanks in advance!
