The Ultimate 140A Off Road Charging System comprises the CTEK D250SA, Battery Monitor and Smartpass 120 pack, and offers a powerful solution that is safe and flexible.

The D250SA delivers 20A of power to charge, condition and maintain any 12V lead acid service battery while on the move. It is compatible with smart alternators, which means that the D250SA will still operate even if the alternator is shut off.

The D250SA also has a built-in temperature sensor that compensates for hot or cold conditions. This ensures that your batteries are fully charged in the shortest possible time without the risk of over or under charging. In addition, it allows for direct connection to solar power sources without the need for a regulator. It features a Maximum Power Point Tracker (MPPT) to get the maximum power out of the solar panels.

The separate CTEK Digital Battery Monitor Display 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.

To complement the D250SA, the Smartpass 120 is a fully automatic 120A power management system that distributes power between the starter battery, the service battery, and your on-board equipment with the need for traditional diodes or VSR relays.

The Smartpass 120 features Dynamic Over Current Protection, providing outputs of up to 350A for up to 10 seconds when powering equipment that require more than 120A. It also has Current Source priority function, wherein it will supply power to critical equipment directly from the alternator when the engine is running. This ensures that critical functions like starters, radios, emergency lights, and communication systems will always have the power needed.

The Smartpass 120 can also assist in starting up your engine if the starter battery is flat by drawing power from the service battery. And with battery temperature protection, it switches off charging when the service battery gets too hot.

This pack has a 2 year Australian Warranty and is without doubt the ideal system for anybody who has serious power requirements when travelling.
