Merlin SmartGauge Battery voltage and charge status monitoring system - 'a fuel gauge for batteries'.


  • The most advanced, yet simplest to use battery state of charge monitor currently available,
  • Unlike ampere hour counting battery monitors, Smart Gauge cannot run out of synchronisation with your batteries,
  • Displays voltage and charge status as a percentage on an easy to read panel, 
  • Suitable for battery types: Open lead acid, sealed lead acid (wet), VRLA gel, VRLA AGM, Carbon Fibre.
While there are many advanced battery monitors available that count ampere hours to display state of charge (by using a current measuring shunt), one drawback can be their accuracy over extended time periods, the Smart Gauge unit uses an advanced computer algorithm to display voltage (2 battery banks) and state of charge (1 battery bank) using just two or three wires.
In addition to being simple to install, Smart Gauge is also very easy to operate - perfect if the individual using the device is not familiar with battery technology. The algorithm used within the unit selfcompensates for the changes in a battery's charge efficiency factor (health) over time, ensuring that the unit remains accurate throughout the life of the installation.
SmartGauge is suitable for both 12 volt and 24 volt electrical systems, provides user settable alarms to indicate both high and low voltages and low capacity. These alarms can be utilised to operate external relays for purposes such as automatic generator starting.
