With award-winning Swedish technology, the dual input D250SA (Part #40-186) can draw its power from smart alternators and other DC sources, making it the ideal charger for vehicles that don’t have access to a main power supply. Its dual input capability means it can draw power from solar and wind sources, in parallel to the alternator.
The D250SA is a fully automatic, 5 step charger that supplies up to 20A of power to charge, condition and maintain any 12V lead-acid service battery from 40-300Ah, including Wet, MF, Gel, AGM. EFB, and Ca/Ca. The D250SA uses patented technology so it’s safe for you and your vehicle’s electronics. It’s also IP65 classified (splash and dustproof, and suitable for outdoor use) and comes with a 2-year warranty.
