With award winning Swedish technology, the dual input D250SE which has now replaced the D250SA  with added 

connection to lithium batteries 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 mains power supply. Its dual input capability means it can draw

power from solar and wind sources, in parallel to the alternator.

maintain any 12V lead acid service battery from 40-300Ah, including Wet, MF, Gel, AGM. EFB and Ca/Ca & lifepo4 Lithium.

The D250SE uses patented technology so it’s safe for you and your vehicle’s electronics. It’s also IP65 classified
