Description


Off road charging with dual input for other DC sources


The D250SA charger can get its energy from alternators, solar panels and wind power. It separates starter and service battery and maximizes the use of the both without risking that the starter battery is unable to start the engine. The SMARTPASS 120 charges and maintains your service battery using 120A from the alternator. It will automatically prioritise critical equipment so radios, emergency lights and navigation systems always have the power they need. The CTEK MONITOR constantly monitors the voltage and current (charge and discharge) to show you exactly how much charge you have and how many hours you’ve got left before your battery bank is empty.
