40A MPPT Solar Panel Regulator Charge Controller 12V/24V Auto Focus Tracking Features: New and high quality MPPT solar charge controller MPPT10-60: Compared with normal solar charge controller, this MPPT controller can increase efficiency by 10%-30%. This controller can charge and discharge at the same time. This MPPT controller has perfect SOC function, controls the charging current and supplies power to the loads. Function: keeps the battery at voltage state. Protects the battery from overcharging. Protects the battery from over-discharging. Protects the battery from reverse charging to solar panels at night. Reverse polarity protection for battery Reverse polarity protection for solar panels When the battery voltage is low, the controller will automatically cut off the load from the system. If the battery voltage is back to normal, the load will start working again. Protection. According to the battery voltage grade, the controller can automatically set the cut-off voltage, cut-off voltage, cut-off voltage. (The parameter is under 25 condition, locked by CPU procedure, cannot be adjusted.) The controller automatically compensates the temperature of the charging voltage according to the changes in ambient temperature. Package includes 1 x Solar Panels Battery Charge Controller 1 x User Manual
