The D250SE with dual input maximizes your vehicle's battery capacity and is the ideal charger for vehicles without access to mains power. The D250SE is a fully automatic charger with a five-stage charging process that provides up to 20 A for any lead-acid battery with a working voltage of 12 V or any service battery of the lithium type from 40 to 300 Ah. It features selectable charging algorithms for AGM and lithium type batteries and can be powered through its dual input via solar or alternator in parallel, as well as wind power. When the service battery is fully charged, the D250SE automatically switches to maintenance charging for the starter battery. The D250SE also delivers a stable current of up to 20 A in vehicles with a smart generator and has a temperature sensor for optimized charging under all weather conditions. 12 V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP).
