All Size Top Quality MPPT Controller DC Brushless Submersible Solar Water Pump

All Size Top Quality MPPT Controller DC Brushless Submersible Solar Water Pump( 3 Years Warranty )( 3 ~ 6 Inches Submersible & Surface Solar Pump )   DC Submersible Solar Pump for Irrigation and ResidentialSolar panels  is to  convert sunlight into electrical energy which will be passed to the solar pump controller,the energy will be used to power the pump. Solar Controller /Inverte is used to stabilize the power voltage and output the power to drive the electric motor of the pump. If backup batteries (optional) are available, then the pump controller can charge them.Battery is for Storaging the additional  energy that can be used at later time when the sunlight may not be adequate to drive the pump.Water Level detector / Sensors is used to connected to the controller and can be used to protect the pump from running dry as well as to automatically turn the pump off when a water tank is full.RISON MPPT Controller Advantage RISON MPPT CONTROLLERCONTROLLER FROM OTHER COMPETITORSAutomaticallyTotally Automatically restarting every morning, or when the sun appears after cloudNot steady, and cannot restart automaticallyEfficiency15-20% higher than common ControllerLower efficiencyMPPT FuctionWith MPPT function(Maximum Power Point Tracking )No MPPTInput Voltage RangeIncrease much larger inpt voltage range to 100V. Will make the panel selection very easy, also avoid too higher input voltage burn the controllerVery smaller input voltage range largest only to 85V, and will be burrnt if the panel voltage increase during the very shinning daytime;Protection Against Wrong ConnectionProtecting against being burned, in case some customers reversed panel"+"/"-"terminals, when connecting onto controller.No protection, will be burned definitelyProtection Against overvoltage/currentThe controller will just keep silent(stop working), when the input voltage/ current is beyond the controllers tolerance;The controller will be burned;High Temperature ResistanceCan run well under 50 degrees condition for 24 hours continually; Will be burned immediately when temperature more than 40 degrees;OperationVery convenient to open the Box to change the SPEED SWITCH;Not convenient, needs screwdriver to open the 4 bolts everytime;Warranty3 yearsNo warranty or longest as 1 year;  /* March 10, 2023 17:59:20 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
