CTEK 20A OFF GRID Battery Charging System w/ D250SA & Digital Display Monitor

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.Specification Brand: CTEK Ambient temperature: -20˚C to +50˚C (- 4°F to +122°F) Positioning: Permanent installation/on board Input: 11.5-23V, 25A Output: 14.4/14.7V, 20A max Back current drain: Corresponding to less than 1Ah/month Battery types: All types of Lead-Acid batteries, 12V, WET, MF, Ca/Ca, AGM, EFB, GEL Battery capacity: 40-300Ah Insulation class: IP65 Ripple: < 4% Warranty: 2 YearsIN THE BOX 1x CTEK D250SA Dual Input Battery Charger 1x CTEK System Monitor 1x User ManualSIZE WEIGHT Carton Dimensions (W x L x H): 6 x 13 x 2cmSKU: CTEK-40-256We accept Change of Mind returns for 14 days after you have received the item in cases where you have changed your mind or made an incorrect purchase and wish to return the product.
