There are several heavy duty marine diesel engines available that require 24 VDC to operate. (without generators) I use batteries for this, but I need a constant/stable charge. My "home power" is also supplied by a diesel generator. In my experience, digital chargers don't like these conditions. Based on the ECM gauge, the engines love this supercharger.
