mppt5012a-duo-bt mppt 12a 12v solar charge controller app regulator for panel charger

-switchable characteristic lines of chargingfor optimum charging of gel/dryfit/agm/fleece or acid/lead-acid,as well aslifepo4 batteries. -increased mppt charging current comparedwith conventional controllers,due to ultramodern controller technology (microprocessor)by 10% to 30%(efficiency>95 %) -unattended charging: standard protectionagainst overload,overheating,reverse battery and back discharge of the battery(in case of insufficient solar power,such as at twilight,at night etc.).
