Go Off the Grid Safely and Reliably


It's the afternoon before a long weekend and all you can think about is hopping in your camper or van and just getting away from it all. What you don't want is to hit the road, get to your secret escape spot, and then not have any power for your equipment.

Don't Drain Your Battery

While driving to your destination, the appliances or TV onboard is draining your extra battery faster than it can charge. An average refrigerator draws 10 amps while the battery only charges at 3 to 4 amps. You don't have to be a math whiz to figure out you're going to run out of battery pretty quickly.

The CTEK 140A Off Road Bundle combines the CTEK D250SE Smart Charger and the CTEK SMARTPASS 120S Complete Management Unit. This system will provide your 4WD, van, RV, or other off-grid vehicles with 140 Amps of charging power, enough to keep your batteries charged and ready. This 12V power system gives you performance and power while extending the life of your batteries.

More Features Used = More Power Needed

All of our vehicles are using more power than ever, off-grid vehicles even more. Many are equipped with winches, high powered lights, lifts, cooking equipment, and more. These vehicles need extra batteries to keep everything running. Unfortunately, the alternator won't be able to keep up with the power drain and the long power lines that run to the equipment add a lot of resistance to the electricity. 

The D250SE & SMARTPASS 120S: An Unbeatable Team

The CTEK D250SE offers continuous fully automatic charging while you're off the grid. CTEK wants to help you get the most from your vehicle and allow you to enjoy your time away from it all. The D250SE protects, charges, and maintains your starter battery and charges your service batteries. It does all of this without putting you in a position of not being able to start your vehicle when it's time to go back home.

The CTEK SMARTPASS 120S provides fast charging using 120A from the alternator. It also allows you to start your vehicle from the service battery if the starter battery was to go dead. The SMARTPASS 120S makes sure that the critical systems like starters, emergency lights, radios and communication systems have the power that they need.

You can use alternative sources of power like solar panels, wind turbines, or even treadmills to provide power to your vehicle, channeling it through the D250SE and SMARTPASS 120S. This system will provide you with the most power from your sources while protecting the sensitive electronics you have onboard your vehicle.

If you take care of your battery, it will take care of you. Let CTEK help you keep your battery fresh and ready to go with our line of smart chargers and accessories. Check out our Charger Selection Tool to find out which charger is right for your vehicle.
