The Millertech 1215-3 is a three-bank onboard charger designed to maintain three separate 12V battery systems simultaneously. Each bank delivers 14.5V at 15A independently, making this a practical solution for boats running multiple house banks, a cranking battery plus house systems, or trolling motor setups that need isolated charging. This is a bench or permanently mounted unit rated for 90-130V AC input, drawing just over 1000 watts at full load.
