Charger 20A Off Grid 12V DC/DC CTEK

20A OFF GRID
Powerful on board charging while you’re on the move
Stay off grid for 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 smart 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.

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.
