Solar cell applications of solar power controller (PV controller and wind and solar controller) to be issued by energy regulation and control, on the one hand the energy sent after adjusting the DC load or AC load, on the other hand to send the excess energy To store the battery pack, when The electricity can not meet the load required, the controller battery power sent to load again. After the battery is fully charged, the controller to control the battery is not overcharged. When the battery is discharged electric energy stored in the solar power market, the controller to control the battery is not over-discharge protection of the battery. When the poor performance of the controller, a large solar power principle affect the life of the battery, and ultimately affect the reliability of the system solar controller main function 1) overcharge protection to avoid charging the battery voltage is too high because of damage caused. 2) Over-discharge protection to prevent battery discharge due to low voltage damage. 3) anti-reverse feature prevents batteries and solar panels due to positive and negative but can not be used even lead to accidents. 4) lightning protection to avoid damage due to lightning and the entire system. 5) The temperature compensation for the temperature difference between the main place to ensure that the battery in the best charging effect. 6) timing control load working hours, to avoid energy waste. 7) When the load is too large overcurrent or short circuit, automatically cut off the load, to ensure the safe operation of the system. 8) overheating protection when the system temperature is too high, automatically stop solar panels to power the load, troubleshooting, automatically resume normal operation. 9) automatic identification system voltage for different operating voltage, automatic recognition, without additional settings.
