The Mastervolt SCM25 is a compact MPPT solar battery charger rated at 25A for 12V and 24V battery systems, with a maximum PV input of 720W. It's the smallest unit in Mastervolt's SCM range and accepts 36-cell, 60-cell and 72-cell modules, so it works with most commonly used solar panels. Built for marine, motorhome and small off-grid installations where space is tight.
