SUUNNY CMP-series solar charge controller is controlled by CPU, According to the voltage ofbattery, controller will adjust the charge current and decide if to supply the loads electricity. The following is the detailed performance:
Generally keep the battery on full voltage condition.
Prevent the battery from over-charging.
Prevent the battery from over-discharging.
Prevent supplying electricity from the battery to solar panels during nights.
Reverse Polarity Protection for Battery
Reverse Polarity Protection for Solar panels
When the current of load exceeds the rated one of controller, the controller will turn into the self-protection state and is automatically locked up, the screen shows Overload.
Short Circuit happens; the Controller will turn into the self-protection state and is locked up, the screen show Short circuit.
Low voltage happens to battery, the controller will automatically separate loads from system. When the voltage of battery goes up, the loads will automatically restart to work.
Protection from the lightning strike
When Controller is normally working, the LCD Screen will show New Charging Current (a dash-before the numeral) , Discharging Current and Voltage of battery every 5 seconds.
Controller is always counting Charging Current Hours and Discharging Current Hours of the Battery.
When controller start up, according to the voltage level of battery, Controller will self-setup the Charging-off voltage, the Load-off voltage, the Load-on voltage. These datum is tacitly approved under the standard environment temperature 25 .
According to varies system temperature, the controller will automatically compensate the temperature of the charging voltage.
Users could setup the Charge-on or off voltage, the load-off voltage, the Load-on voltage, etc, according to their requirements.
To prevent battery from over discharging, Controller will automatically control the lowest Load-off voltage of the load, which is no less than 10V (as per 12V battery) or 20V (as per 24V battery). If voltage of the battery is less than 10V (or 20V), the button - will stop working.
To recover its defaults, please keep pressing down the button Menu for over 5 seconds.
