Features: Efficient MPPT controller algorithm. MPPT efficiency is not less than 99.5%, and the conversion efficiency of the whole machine is up to 98%.Charge mode: three stages (fast charge, constant charge, floating charge), effectively prolonging service life of the batteries.Multi Load modes: normally open/off mode, PV voltage control switch mode, dual-period mode.Much information is displayed on LCD: system type, PV input voltage, PV input current, Day/Month,Total generated energy, battery type, battery voltage, charging current, charging power, Load current, Load power and so on.Customers can choose battery types(Flooded, Sealed lead acid, Gel battery) to charge.RS485 communications provide communication protocols to facilitate unified management of users.
