Features:100% brand new and high qualityMPPT solar charge controller MPPT10-60: 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.This MPPT controller has perfect SOC function, control charge current, and supply power to the loads.Function: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 protectionAccording 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.Package Includes:1 x Solar Panels Battery Charge Controller1 x User Manual
