Most vehicle alternators are not designed to fullycharge your auxiliary batteries. In fact most aren’tdesigned with auxiliary batteries in mind at all.An insufficient charge will shorten the life andperformance of your battery investment and mayeven result in a flat battery when you least expect it.The REDARC BCDC1225, 25 amp In-vehicleBattery Charger is a three stage DC-DC batterycharger that operates from any input between9 and 32 volts DC.It is designed to charge any commonly usedautomotive battery to 100%.The BCDC1225 also features a Maximum PowerPoint Tracking (MPPT) solar regulator, allowing youto deliver the maximum amount of power fromyour solar panels to your auxiliary battery.What is MPPT and how does it work?Every solar panel has a point at which a particularcombination of current and voltage output resultsin the maximum power output. In the diagram,the curve is an example of the standard outputexpected - the maximum power point is at theposition marked on the diagram.AMPSMPPT IV and PV curvesMaximumpower pointVOLTSWATTSIf the output can be regulated to the voltage andcurrent levels needed to achieve the maximumpower output, the panel will achieve the mostefficient rate of power generation.This regulation results in the output from your solarregulator providing the maximum current possibleat the required voltage.In low light level situations it will compensate forthe low light level and find the point at which thesolar panel delivers its maximum available power.MPPT ensures that you get the most powerpossible from your solar panels, even duringlow light level conditions.There is a range of BCDC models for different vehiclecharging systems and battery bank sizes.
