The dual input allows it draw power from solar and wind sources as well. The D250SE can charge lead acid batteries up to 300Ah as well as AGM.Gel.Lithium and more. It can supply these batteries with up to 20A of power to charge and maintain them. SmartPass allows energy produced from solar.AC chargers and alternators to be synchronised to maximise output and minimise charge time. The energy is then able to be distributed to different battery banks and/or equipment such as lights and navigational systems that need additional energy supply.ensuring the battery remains fully charged. Smartpass makes sure that all of your applications have the power they need.they need it. Handles inputs of up to 120A and battery capacity of 28 - 800Ah.with all types of 12V lead batteries including Wet.Gel.and more.
