VOLTAGE:DC12V/24V Self power consumption:20MA Rated charging current: 20A Rated load current: 20A Overcharge Protection: 14.4V/28.8V Overcharge Float charge: 13.5V/27V Overcharge Recover: 13.2V/26.4V Over discharge Protection: 10.8V/21.6V Over discharge Recover: 12.3V/24.6V Load overvoltage Protection: 16.5V/34V Load overvoltage Recover: 15V/30V Maximum solar battery open circuit voltage: 25V/36V Working temperature: (-20℃- +50℃) Operating instructions Open the cover, do the cable connection. Step 1.Connect the accumulator to the 3rd and 4th termination (from left to right) according to the '+','-'. *Remark: 'load' light flash one time, after 15 to 30s, it turns into solid status, So it means the connection is correct, otherwise you should correct the connection. Step 2. Connect the Solar cell to the 1st and 2nd termination (from left to right) according to the '+','-'. Step 3. Connect the load to the 1st and 2nd termination (from left to right) according to the '+','-'. Step 4.'Charge' light turn to solid status. It means working at normal charging status. If it is flashing, it means working at float charging status. If it is dark, charging is stopped. Step 5.'Load' light turn to solid status. The load can work. attention 1.Befor connect to the controller, make sure the rated voltage of solar panel, accumulator and load should be same.(6V,12V,24V) 2.The rated current of solar panel and load should less than the rated current of the controller.
