  • D250S Dual

    CTEK the standard for DC to DC charging

    If you need a dual battery setup look no further

    The D250S Dual is what we call a DC to DC charging system. In this case with dual inputs, one from solar and one from an alternator. The solar input is up to 22VDC @ 25A, this outputs through the 20A 5 stage charging output profile and is considered the master input. The second input is from a vehicle's alternator which typically is supplying a voltage suited to the engine's management system or starting battery. Its almost never the correct charging voltage for what could be a flat house bank in the rear of the vehicle where the voltage drop over 3-5 metres could be 1 volt. This unit installed in the rear with the house batteries will ramp up the voltage to what's needed for the house battery to keep it well maintained at up to 20A, this is the slave input. By that we mean if you are in the sun the solar has priority charge of say 5A so that the engine doesn't need to work as hard to provide power for the other 15A that could be charging of the house batteries were flat. 

    If you have a newer Euro 5+ vehicle then you should consider reviewing the latest release from CTEK the D250SA with its ignition feed and wider operating alternator input voltages. 

  • D250SA

    Euro Performance Upgraded

    The latest from CTEK the D250SA leverages on the good foundation of the D250S Dual but raises the stakes again by including an ignition feed to only take energy from the start battery when the vehicle is running. An additional feature allows setting of bulk charging voltages at either 14.4V or 14.7V. A wider input voltage range on the alternator side for Euro 5+ engine for ECU controlled systems.

    A wider input voltage range on the alternator input side for Euro 5+ engine for ECU controlled systems allows for forced charging of the service batteries to optimise the engine output and generate charging power.

    MPPT Solar input, alternator input with service battery charging from the solar or engine with a preference on the suns free energy. Not to mention the ability to add the SmartPass or SmartPass 120 for an additional 80A or 120A charging output.

  • Off Grid Bundle

    Monitored charging to keep you off grid longer

    The CTEK 20A OFF GRID CHARGING SYSTEM charges your battery bank while you’re driving to stop it going completely flat so you can spend more time off grid. You can charge it from alternator, solar or wind power and, for complete peace of mind, you can see at a glance how much charge you’ve got left and the length of time till your batteries are discharged.

    D250S DUAL The D250S DUAL 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. SYSTEM MONITOR The System Monitor constantly monitors the voltage and current (charge and discharge) to show you the exact how much charge you have and how many hours you’ve got left before your battery bank is empty.

  • Off Road Bundle

    The ultimate 12V power system for outdoor vehicles

    Battery to battery charger in a dual battery application

    Enjoy the outdoors for even longer with CTEK’s 100A OFF ROAD CHARGING SYSTEM. It combines the D250S Dual Smart Charger and the SMARTPASS Power Management System for the ultimate 12V power system. Install it in your 4WD, camper trailer or caravan to give you the best performance, power and life from your batteries.

    D250S DUAL The D250S DUAL 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. SMARTPASS SMARTPASS is a Power Management System with under voltage protection that distributes it to the service batteries or electrical equipment. SMARTPASS separates and prioritized between critical and non-critical consumers to avoid drained service battery. SYSTEM MONITOR The System 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.

  • SmartPass 120

    DC Battery Management System

    When you need to charge a large service battery bank or just better manage a situation where a second battery is needed. With an isolated low voltage disconnect circuit, you can ensure essential communication or navigation lights are left running while non-essential equipment is turned off to save the batteries power.

    The additional 120A of charging power means battery banks up to 1200Ah can be serviced with the addition of the D250SA solar input is also utilised to ensure maintenance charging is continued during storage or a period of non-use.
