We take a look at the ultimate 12V 4WD and camping power management system the CTEK 120A Smart Pass and D250SA Smart Charger
Often we find ourselves off the grid for extended periods. Being away from power outlets and energy grids does not mean you have to stop using your lighting and electronics. We rely on some excellent gear to ensure that we can keep our fridges running, our lights glowing and our laptops and cameras powered. Here we take a look at one of the best 12V charging and power management systems on the market.
This system comprised of two products from CTEK provides reliable power to your vehicle battery and leisure battery while on extended trips off the grid.
The D250A charger is a versatile charger that can charge from an alternator or plug straight into an external solar panel as it contains a built in solar regulator. It can be installed in old and new vehicles due to its compatibility with more modern smart alternators. Its in built temperature sensor automatically increases the voltage in cold weather and decreases the voltage in warm weather ensuring safe and optimal performance from the system. The D250A charger is only part of the system however.
The Smart Pass 120A power management system which directs the charge to your service battery and supplies current to consumers separately. Used together with a CTEK D250SA, SmartPass provides optimal charging for the batteries at all times.
SmartPass also has an integrated ‘battery guard’ which protects deep-cycle batteries from discharging completely which can seriously damage a battery. In addition, this function also ensures that critical equipment such as radio, emergency lights and navigation systems always have enough power to function.
The system can handle current up to 120 Amps and is suitable for battery banks of between 28-800Ah. It’s suitable for all types of 12V lead-acid batteries and is IP65 classified (water jet and dust protected and approved for outdoor use).
There is also a special function to help you out if your main starter battery is flat, with a start assistance function. This system is a permanent and reliable part of our camping gear.
