Controller Information Solar Charge PWM4024A-12v / 24v 40A LCD


Charger controller solar  PWM  is the latest technology currently used algorithms advanced tracking to make modules of solar activity in voltage ideal that the module power of sun Heaven can produce the maximum power available. 

Compared to  conventional controllers , PWM technology  is equipped with temperature compensation function, which can make the efficiency of photovoltaic modules increase by 10% – 30%, and can extend battery life. storage.

Main function:

* Compared to normal charging solar controller, this PWM controller   can increase efficiency by 10% -30%

* Can charge and discharge at the same time

* Always keep the  battery  in full state

* Protect the  battery to  discharge too much

* Protection to prevent the  battery from  discharging back to the solar panels during the night

* Protect pole reverse  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 battery  voltage  is back to normal and the load will restart working.

* Protection of thunder when it rains

* The controller will automatically compensate the temperature of the charging voltage according to changes of the ambient temperature
