The CTEK D250SA charger is the ultimate dual battery and dual energy management system for lead acid batteries found in motorhomes, buses, campervans or even dual battery installations in standard 4WD's. Providing two DC inputs and obtaining its power from either an alternators, solar panel, wind power or other DC energy. The D250SA automatically selects the best connected DC energy source from its two inputs and provides CTEK's state of the art 5 stage charging process to the connected battery.
Ideally suited for caravans or motor homes with solar panels. Leaving CTEK D250SA to determine the best available energy and maintain and charge the house batteries. Charging automatically starts as soon as DC energy is provided to the charger, such as from alternators when a vehicle is started or from solar panels when connected. The D250SA has a temperature sensor which ensures optimal charging voltages at all temperatures.
