The D250SA charger can get its energy from smart 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 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.
