Programmes include: Semi Traction Open Lead/Acid, Leisure Lead/Acid, Sealed Lead/Acid (High Calcium), Gel, AGM, Lifeline, Odyssey, Optima and custom programmes. Installation comprises of connecting 3 wires and telling the unit which style of battery you have. The Merlin SmartGauge’s large LED display is easily read in all lighting conditions and the unit is suitable for 12 and 24V battery banks.
#Battery logger generator#
A volt-free contact on the rear of SmartGauge allows you to trigger external alarms, auto generator start etc.
#Battery logger software#
We cannot confirm if there is a free download of this software available. It is fitted with a high/low voltage alarm for each battery and low % remaining alarm. Battery Logger 1.0 was available to download from the developers website when we last checked. It logs 30 days of data with a nice and simple user interface. The Merlin SmartGauge will also display battery voltage for your engine battery. This is a temperature logger for the internal battery, which means that it will always be at least a little warmer than the room temperature, and this is especially true when the device is in use or charging. SmartGauge displays real-time capacity remaining so you are never surprised by running out of power early. Bearing in mind that batteries lose around 10% of capacity per year, this means that inherent inaccuracies grow. Conventional monitors always show % remaining of theoretical capacity when the battery was new – not actual. The Merlin SmartGauge displays the battery voltage for your domestic battery bank and % remaining.

In recent independent tests by leading battery manufacturer, Enersys, The Merlin SmartGauge was found to be more accurate than conventional battery monitors. What’s more, installation is easier and SmartGauge can be easily used and understood by all crew members.

Real-Time battery measurements and proprietary algorithm coupled to computerised battery models allow SmartGauge to always provide real-time battery % of charge remaining AND will never run out of synchronisation with the battery. The Merlin SmartGauge uses a completely different type of monitoring method. This means that conventional monitors run out of synchronisation and after a time can display misleading information. The problem is that an amp hour changes according to temperature, discharge rate, charge rate and condition of the batteries. The Merlin SmartGauge Battery Monitor is the most accurate battery monitor currently available today.Ĭonventional battery monitors use a Current Measurement Shunt to ‘count’ amp hours in/out of a battery.
