Description product description The MPPT30 controller is an intelligent, multi purpose solar charge and discharge controller. This series of products uses a customized LCD display with a very user friendly interface; each control parameter can be flexibly set to meet your different needs.MPPT30 has the following features MPPT function The controller is characterized by intelligently adjusting the working voltage of the solar power board to track the maximum current of the solar panel, so that the solar panel always works at the maximum power point of the V A characteristic curve. Compared with ordinary solar controllers, the utilization of solar panel power generation is increased by 10 30%; Image LCD graphic symbol, simple button mode; Intelligent PWM charging mode with automatic temperature compensation; Adjustable slave discharge control parameters, configurable load operating mode; Battery reverse discharge, under voltage, reverse connection protection and other protection functions.Parameters/ModelT10T20T30T40Maximum Power Current10A20A30A40AInstallation Lin mm24mm28mm210mm212mm2Installation Line(AWG)10 (AWG)8(AWG)7(AWG)6(AWG)Weight280g300g475g480gDimensions1438946 mm187*97*61 mmSystem load lossless than or equal to13mALoop Buckless than or equal to100mVBattery float voltage1 8V 12V system /27.6V 24V systemBattery under voltage) protection10.6V 12V system /2 2V 24V systemBattery (under voltage) recovery voltage1 6V 12V system /2 2V 24V systemCharge modeMPPT+PWM MODEOperating Temperature 10~60CStorage Temperature 30~70CHumidity requirementsless than or equal to90%, No condensationTemperature compensation 4mV/Cell/CTemperature Probe (built components)NTC 100K thermistatsMaximum open circuit voltage of the solar panel18V 24V 12V system 36V 48V 24V system)Solar panels maximum open circuit voltage (V)less than or equal to48V(Cases) 12V system standard configurationThe peak voltage of the solar cell panel18V 25V18V 25V18V 25V18V 25VPeak power of solar cell panel50W 130W100W 260W200W 380Wless than or equal to500WModelT10T20T30T40Battery standard voltage12V12V12V12VBattery capacitymore than or equal to100AHmore than or equal to200AHSpecifications Solar controller 30A 12/24V MPPT LCD intelligent automatica identification charging and discharging circuit light controPackage Included 1 10/20/30/40A controller1 manual1 temperature probeNotes Due to the difference between different monitors, the pictures may not reflect the actual color of the item.Compare the detail sizes with yours, please allow 1 3cm error, due to manual measurement.Please leaving a message before you give the bad feedback, if the products have some problems.Thanks for your understandings.
