The Battery Monitor is primarily designed for monitoring a marine battery. However you can use the Device with any single DC source (i.e. alternator wind generator etc.) or load (windlass refrigerator etc.). This capability increases both marine safety and sailing comfort by giving you full information about on-board DC sources and consumers.
To operate as intended the Battery Monitor requires an appropriate external shunt shunts in the range from 5A to 1200A are widely available. The Device should be properly wired and configured. At the minimum you should specify drop voltage and maximum current for connected shunt. In addition you can specify battery parameters such as nominal capacity and voltage chemistry etc.
Current and voltage measurement data and in case of batteries calculated data (state of charge consumed ampere-hours battery time remaining) are output to an NMEA 2000 network and can be displayed on MFDs or instrument displays.
