Feature 1Use CPU processor superior speed performance. 2The high precision A/D sampling to ensure the accuracy of sampling. 3The efficient tandem PWM charging mode, extend battery life, improves the system performance. 4The controller with over temperature, over discharge, overload, short circuit protection function. 5Radiator heat dissipation is fanless designed and fanless design. Dust is difficult to enter, sealed well, with sufficient material, no suction, low power consumption, effectively avoiding noise. 6The photovoltaic array and reverse battery protection function. 7Standard RJ45 interface equipment that can be used for connecting the liquid crystal display unit or PC monitor software and communication peripherals, it is convenient for the user view the controllers running data, modify the controller control parameters. 8Use of RS-232 communication, the communication speed and communication protocol compatibility are very well.Specification .wang-edit-text{ font-family:'Arial' !important; } .wang-edit-text table { border-top: 1px solid #000; border-left: 1px solid #000; } .wang-edit-text table td, .wang-edit-text table th { border-bottom: 1px solid #000; border-right: 1px solid #000; padding: 3px 5px; } .wang-edit-text table th { text-align: center; }Item Type: Solar Charge ControllerOptional Model12V/24V 10A, 12V/24V 20A, 12V/24V 30ARated voltage12V/24Vauto48VBattery maximum voltage15V/30V/60VSolar panel maximum voltage22V/44V/88VRated charging current10A20A30A40A50A60ACharging line voltage drop0.7VDischarging line voltage drop0.2VStatic loss0.2WcommunicationRS232/RJ45InterfaceUSB output0.5A/5VOver-temperature protectionBelow 75 full current75-90 half current above 90 off chargeWorking environment parametersLCD display temperature-20-75Working environment temperature-20-50Storage temperature-30-70Protection levelIP30Mechanical parametersWire terminal)2.5610101616Size LxWxHmm)165 x 100 x 50mm / 6.5 x 3.9 x 2.0in207.5 x 129 x 69.5mm / 8.2 x 5.1 x 2.7inNet weightkg0.350.380.401.301.351.40Battery voltage parametersBattery voltage parameters are based on 25/12V system24V system X248V systemX4Battery parametersBattery typeColloid lead acid batterySealed lead acid batteryLithium iron phosphate batteryManganateLithium batteryUserdefinitionOver-charge disconnect voltage (V)15.515.513.214.413-16Overvoltage recovery voltage (V)14.815.012.614.013-16Equilibriumcharge voltage (V)14.614.612.413.813-15Enhance charge voltage(V)14.214.412.213.613-15Floating charge voltage(V)13.613.812.013.212-14Under-voltage recovery voltage(V)12.612.811.512.611-13Under-voltage shut down voltage(V)10.810.89.610.59-11Equilibriumcharge duration(min)12012012060-180Enhance charge duration(min)12012012012060-180Light control voltage parametersLight control turn on voltageMaximum10VMin6VDefault8VLight control turn off voltageMaximum8VMin2VDefault4VBattery temperature compensation parametersTemperature compensation parametersMaximum0mV2VMin-8mV2VDefault-4mV 2V based on 25Equilibrium, enhance, floating, enhance recovery voltage, low voltage disconnect recovery voltage, under voltage alarm recovery voltage, under voltage alarm voltage, low voltage disconnect voltages temperature compensation parameters are the samePackage List1 x Solar Charge Controller1 x English ManualNotePleasenotethatthenewtypeandoldtypeofthisproductwillbesentrandomly,andmakesureyouwillnotmindbeforeordering.
