Ⅰ Features                                                                                        

 1. Intuitionistic LED indicators show the current system battery capacity, charging and discharging state of the battery.                                                                                    

 2. Having the protection functions as overcharging, over discharging, overload, short-circuit and reversed connection.                                                                                       

 3. Tandem type PWM charging makes the charging efficiency increase by 3% to 6%, compared with non-PWM charging.                                                                                              

 4. The parameters of charging and discharging have been set during the production (special parameters need to be told in advance), so no need to adjust the parameters.                                                              

 5. It can set the working mode of the load.                                                                

 6. USB charging function (optional).

1.Charging and display: After the controller is connected right, if the charging indicator is still not illuminating, this means the sunshine is weak or there is not sunshine.And if the charging indicator is illuminating, it means the controller is charging the battery. When the indicator flickers, it means the battery enters into float charging mode, and this can make the battery at full charging state to lengthen the longevity of the battery. Only when the controller detects the battery over discharging, can it start the hoisting charging mode.                                                                                

2. Battery capacity and display: When the battery indicator is red flickering, the load will shut time-delayed to protect the battery.

3. Load state and indicator: When the load indicator is green and flicker , the load will be shut.
