Solar charge controller Electronic protection Fully automatic operation PWM charge mode(SOC) Microcontroller digital accuracy Suitable for all 12/24V DC lamps Big terminals,big distance between terminals Double digital LED display,numbers equal to timer setting Temperature compensation(with external temperature sensor) 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 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 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 Specification General Model:CMTP02 Rated Voltae :12V / 24V Max Load current: 30A Input voltage range: 12V?20V/24V~40V Length?1m:Charge loop drop:<250mV Length?1m:Discharge loop drop: <50mV Full charge cut: 1.37V?14.4V/27.4V?28.8V (data under no load condition) Low voltage cut: 10.5V?11V/21V?22V Temperature compensation: -3mV/?/cell No load loss: ?20mV Efficiency: 95%?97% Max wire area: 6mm2 Ambient temperature -25 ? -55 ?
