1. Overchargeprotection: When the charging voltage is higher than the protection voltage,the battery will be automatically shut down to charge the battery. After that,when the voltage drops to the sustaining voltage, the battery will enter thefloating charge state. .

       2.Over-discharge protection: When the battery voltage is lower than theprotection voltage, the controller automatically turns off the output toprotect the battery from damage; when the battery is recharged, it canautomatically restore power.

       3. Loadover-current and short-circuit protection: After the load current exceeds ratedcurrent or the load is short-circuited, the fuse is blown, and it can be usedafter replacement.

       4. Over-voltageprotection: When the voltage is too high, the output is automatically turnedoff to protect the appliance from damage.

       5, withanti-recharge function: using Schottky diodes to prevent the battery fromcharging the solar cell.

       6, withlightning protection function: When a lightning strike occurs, the varistor canprevent lightning strikes and protect the controller from damage.

       7. Reversepolarity protection of solar cell: The polarity of the “+” and “-” of the solarcell is reversed. You can continue to use it after correction.

       8. Reversebattery protection: The battery “+” and “-” are connected in reverse polarity,and the fuse is blown. It can be used after replacement.

       9. Battery opencircuit protection: In case the battery is open, if the solar battery is normallycharged, the solar charge controller will limit the voltage across the load to ensure thatthe load is not damaged. Without electricity, nothing will happen.

       10. With temperature compensation function.

       11.Self-inspection: When the controller is affected by natural factors or improperoperation, it can let the controller self-inspect, let people know whether thecontroller is intact, reduce a lot of unnecessary man-hours, and createconditions for winning project quality and duration.

       12. Recoveryinterval: It is the recovery interval for over-charge or over-dischargeprotection, to avoid load resistance caused by line resistance or batteryself-recovery.

       13. Temperaturecompensation: monitor the temperature of the battery, and amend the charge anddischarge values to make the battery work in an ideal state.

       14, lightcontrol: mostly used for automatic lamps, when the environment is brightenough, the controller will automatically turn off the load output; and whenthe environment is dark, it will automatically turn on the load to achieve thefunction of automatic control.
