Brand:GLCountry/Region of Manufacture:HKMPN:Does not applyUPC:Does Not ApplyHello! Welcome to our store!Quality is the first with best service. customers all are our friends.Fashion design，100% Brand New，high quality!Compared with normal solar charge controller， this MPPT controller could increase efficiency by 10%-30%.This controller can charge and discharge at the same time. It has perfect SOC function， control charge current， and supply power to the loads.Features:Always keep the battery on fill voltage condition.Prevent the battery from over-charging.Prevent the battery from over-discharging.Prevent the battery from reverse charging to solar panels during nights.Reverse Polarity Protection for BatteryReverse Polarity Protection for Solar PanelsWhen the battery voltage is low， the controller will automatically cut off the load from the system.If the voltage of battery is back to normal and the load will restart working.Thunder protection.According to the battery voltage grade， the controller can automatically set charge-off voltage， the load-off voltage，the load- restore voltage. (The parameter is default under 25℃ condition， locked by the CPU procedure， cannot adjust.)The controller will automatically compensate the temperature of the charging voltage according to the changes of ambient temperature.Specification:Rated charge current: 30ARated load current: 30AWork voltage: 12V/24V AUTOVoltage of stop power supply: 10.8V or 21.6VVoltage of resume power supply: 12.6V or 25.2VVoltage of stop charging: 14.4V or 28.8VTemperature coefficient of voltage stop charge: -3mV/℃ cellWorking temperature: -20℃~+60℃What You Get:1 x Solar Charge Controller1 x English user's manual
