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.Specification:Condition:100% Brand newMaterial: Aluminum AlloyColor: As shown in picturesWeight: 2.6KGSize: Approx.18*27.1*8.5cm / 7.09*10.63*3.35inCable Length: 135cm / 53.15inRated Charge Current:60ASystem Type: DC12V/24V/36V/48VNo Load Loss: 30mAOperation Temperature: -20-+50Storage Temperature: -40-+75Breaker: >100ATemperature Compensation: -3mV//2V(default)Temperature Factor: 0.002%/Output Ripple: 200mVOutput Voltage Stability Precision: 1.5%Max Input Voltage: 150VPackage Lists:1 x Controller1 x Manual1 x Screwdriver1 Pack of ScrewsNotice:Please allow 1-3cm error due to manual measurement and make sure you do not mind before ordering.Please understand that colors may exist chromatic aberration as the different placement of pictures.
